The person in charge of the Department of Environmental Impact Assessment and Emission Management of the Ministry of Ecology and Environment answered questions from reporters about two standards, such

  Recently, the Ministry of Ecology and Environment has issued the technical guide for accounting the pollution sources of automobile manufacturing and ceramic products manufacturing (hereinafter referred to as the "guide") as the national environmental protection standard. The relevant person in charge of the Department of Environmental Impact Assessment and Emission Management of the Ministry of Ecology and Environment answered the reporter’s questions on the compilation background, main contents, industry characteristics and implementation focus of the guide.

  Q: What is the position of the technical guide of source strength accounting in the EIA technical system? What problems are mainly solved? What is the overall progress in the construction of the current source strength system?

  A:The environmental impact assessment system has been developed in China for nearly forty years. Along the way, the technical guideline system of environmental impact assessment has developed from scratch, from scattered to systematic, and has formed a relatively complete technical specification system composed of guideline general outline, factor guideline, industry guideline, thematic guideline and source strength accounting technical guideline. Among them, the source intensity guide is a technical method to standardize the selection and accounting of pollutant source intensity in construction projects, which is conducive to mastering the emission law of pollution sources, improving the accuracy and scientificity of source intensity accounting, and providing support for the fine management of pollution sources.

  In view of the problems existing in the source strength accounting of environmental impact assessment of construction projects, such as incomplete identification of pollution sources and determination of pollutants, insufficient consideration of the activity level of pollution sources and the effective time of discharging pollutants, and nonstandard and inconsistent accounting methods, the source strength guide unifies the source items such as pollution sources and pollutants, and solves the problem of missing items in source strength identification in environmental impact assessment; The accounting period is unified, reflecting the effective time of pollutant discharge from various pollution sources in the industry, especially considering the characteristics of equipment that runs intermittently and equipment that needs maintenance and shutdown; Unifying the calculation method is convenient for the examination and approval personnel to judge the quality of project EIA documents from a technical point of view, which is of great significance to improve the management level of project EIA. Since 2018, the Ministry of Ecology and Environment has successively issued the Technical Guidelines for Pollution Source Strength Accounting (hereinafter referred to as "Guidelines") and the source strength guidelines for 17 key industries such as thermal power, pulp and paper, steel, cement, flat glass, pharmaceuticals, pesticides and fertilizers, which have played a positive role in standardizing industry source strength accounting.

  The source strength guidelines for automobile manufacturing and ceramic products manufacturing issued this time are the development and improvement of the standard system of source strength guidelines, and the overall idea continues the requirements of the guidelines. In the identification of pollution sources, it covers all processes, places, facilities or devices that may produce waste gas, waste water pollutants, noise and solid waste; In accounting methods, including the measured method, material balance algorithm, pollution coefficient method, analogy method and experiment method. In addition, the overall framework and content are consistent with the published source strength guide. In the next step, we will promote the compilation and revision of the source strength guide according to the management needs.

  Q: After the institutional reform, the responsibility of pollutant discharge permit was assigned to the newly established Environmental Assessment Department. Compared with the previous guidelines, what work has been done in the connection with pollutant discharge permit?

  A:The technical guide of source strength accounting is an important means to accelerate the reform of environmental assessment and licensing system and establish a streamlined, efficient, scientific and reasonable environmental management system for stationary pollution sources. The previously published series of source intensity guidelines have been fully connected and consistent with the Technical Specification for Application and Issuance of Pollution Discharge Permit (hereinafter referred to as "Permit Specification") in terms of application scope and accounting method, including making it clear that the source intensity guidelines are applicable to new (renovated) and existing engineering pollution sources, and can be used for environmental assessment, pollution discharge permit and other fixed pollution source management, among which the accounting method of organized source intensity of existing engineering waste gas and wastewater is the same as the permit specification.

  After the institutional reform, in order to implement the requirements of the Notice on Doing a Good Job in Linking the Environmental Impact Assessment System with the Discharge Permit System (Environmental Assessment [2017] No.84) and promote the deep connection between the environmental assessment and the permit system, the two guidelines issued this time have deepened the following contents: First, it is proposed that the emissions of major discharge outlets and general discharge outlets need to be accounted, which is consistent with the permitted emissions calculated by the permit specification; Second, in the attached table "List of Accounting Results and Related Parameters of Pollution Sources", the column of "Discharge Outlet Type" is added, which requires identifying the main discharge outlet and general discharge outlet corresponding to a single pollution source, which is not only connected with the permit, but also based on the requirements of Atmospheric Environment (HJ 2.2) (hereinafter referred to as "Atmospheric Guide"), and accounts for the organized discharge of the main discharge outlet, general discharge outlet and the whole plant, so that the source can be controlled.

  Q: What are the characteristics and innovations of the automobile manufacturing source guide from the industry point of view?

  The main pollutants emitted by automobile manufacturing industry are volatile organic compounds (VOCs), which is a major concern in the Three-year Action Plan to Win the Blue Sky Defence War, the Work Plan for the Prevention and Control of VOCs Pollution in the Thirteenth Five-Year Plan and the Comprehensive Treatment Plan for VOCs in Key Industries. The characteristics and innovations of this guide in the industry mainly include:

  First, the accounting method highlights the characteristics of the industry, especially the use of volatile organic matter material balance algorithm is refined.For the material balance algorithm that the source of volatile organic compounds in automobile manufacturing industry belongs to "organic solvent use" and is discharged through "non-single process", the emission standard compilation process of American Air Pollutant Emission Factor Compilation (AP-42 Manual), German Institution of Engineers "Emission Control-Mass Production of Automobile Body Painting" (VDI3455 Standard) and automobile manufacturing places such as Beijing, Shanghai, Shandong, Guangdong and Zhejiang are integrated.

  The second is to implement the latest standards and environmental protection policies.For example, the requirements of "dual control of emission concentration and removal efficiency" put forward in the newly issued Unorganized Emission Control Standard for Volatile Organic Compounds (GB 37822) and the Notice on Printing and Distributing the Comprehensive Treatment Scheme for Volatile Organic Compounds in Key Industries (Huan Da Qing [2019] No.53) are fully reflected in the accounting requirements of the vehicle source strength guide.

  Q: What are the characteristics and innovations of the source strength guide for ceramic products manufacturing from the industry point of view?

  Ceramic products manufacturing industry has a large emission of air pollutants, which is the key control industry determined in the Comprehensive Control Plan for Air Pollution in Industrial Kilns. The main emission sources are firing kilns and spray drying towers (hot stoves). The characteristics and innovations of this guide in the industry are as follows:

  First, it is clear for the first time that when the material balance algorithm is used to calculate the intensity of sulfur dioxide source, the sulfur input by fuel and the sulfur input by raw materials should be considered comprehensively.In the process of compiling the guide, a confirmatory experiment was carried out to study the transportation and transformation of sulfur in ceramic products industry, and 42 samples from 6 companies were tested, resulting in 22 test reports. The experimental results show that the proportion of sulfur input from raw materials is high when using clean fuel, and the sulfur input from raw materials should be considered in the sulfur dioxide material balance formula.

  The second is to further understand the operation of ceramic products manufacturing facilities and the law of waste gas emission, which is reflected in the accounting requirements.The appendix of the guide gives the data reference values of the emission laws of waste gas pollutants from the main production facilities and processes of ceramic products manufacturing, including the fluctuation of source intensity in facilities hours, the generation laws of pollutants such as normal production, shutdown arrangements and annual emissions, which is of great guiding significance for reasonably determining the source intensity and prediction parameters, facilitating the application of source intensity accounting results to atmospheric guidelines, guiding specific construction projects to set up reasonable prediction scenarios, and scientifically carrying out predictions and judging the acceptability of environmental impacts.

  The third is to clarify the requirements of special circumstances such as limited production and suspension of production in the ceramic products industry.Under special circumstances, such as dealing with heavy polluted weather, the situation of stopping production in ceramic products manufacturing industry is not regarded as "abnormal working conditions" referred to in the guide. It is clear in the appendix of the guide that the situation of stopping production and limiting production should be considered when calculating the allowable emissions.

"Qingyu Nian" was sued for paying ahead of time. How can Tencent iQIYI earn a decent income?

It seems that 50 yuan has triggered a lawsuit, but it is actually a collective counterattack by consumers against the company’s business model.

Text | Sixth Sense

It is difficult to make a play, even more difficult to watch a good play, and it is even more difficult to follow the hit online drama "Celebration of More Than Years". How difficult? 50 yuan, making Tencent Video and VIP members enemies and going to court.

On December 11, 46 episodes of "Qingyu Nian" were broadcast to 22 episodes, and a charging window suddenly popped up on the screen. Fans who were chasing the drama were informed that Tencent Video and iQIYI Video had launched the "Qingyu Nian" VIP advanced on-demand service, that is, on the basis of VIP watching 6 episodes first, VIP members can watch 6 more episodes during the update by paying another 50 yuan.

VVIP is set up outside of VIP, and the on-demand mode directly touches the bottom line of users, causing thousands of waves with one stone. Some users are angry: "It’s too ugly to eat" "It’s crazy to think about money" "This operation is really slutty." The People’s Daily immediately issued an article criticizing "some websites that are caught in the water, burning forests and hunting, and destroying their future." For a time, the video platform became the target of public criticism, and the criticism was boiling.

Things continued to ferment until December 17, and Tencent and iQIYI, who were unable to bear the pressure of public opinion, responded one after another, admitting that they were "not considerate enough to members’ consumption psychology". "The original intention was to meet user requests, but it was not done well." However, as of December 19, the advanced payment on-demand model was still not removed from the shelves. iQIYI adjusted the charging rules to VIP members to conduct on-demand at a price of 3 yuan per episode. After watching the rest of the plot, it cost a total of 63 yuan, which did not drop but rose.

In the face of a series of operations on the video platform, most users said they could no longer bear it and had to protect their rights. Weibo blogger @logos logicspublished a public post on the 19th, saying that he had sued Tencent, demanding confirmation of multiple terms under the Tencent Video Super Film and Television VIP membership service agreement, and compensation for economic losses of 500 yuan. This move triggered 24,000 people to participate in the discussion, and the number of supporters continued to rise.

A domineering president-like increase in money on demand has made the video platform a "public enemy of the whole people". Regardless of whether the lawsuit is won or lost, the platform’s reputation has been greatly backlashed. It seems that 50 yuan has triggered a lawsuit, but it is actually a collective counterattack by consumers against the business model of the enterprise. For video platforms, business conduct is understandable, but how to make users willing to pay for a variety of payment methods and earn decent money? This requires deep thinking.

Is it worth watching 6 more episodes for 50 yuan?

In fact, the model of advanced on-demand is not the first of "Celebration of More Than Years". This summer’s hot "Chen Qing Ling" also adopted the method of advance on-demand in the final finale. Whether it is VIP or SVIP, users can pay 6 yuan for a single episode, or directly unlock it for 30 yuan to the finale. In addition, the finale is not sold alone, that is, users must spend 30 yuan to see the finale.

This move also attracted a crusade, but at the same time, users have to pay for it, more than one million people pay on demand, according to the package price of 30 yuan, Tencent overnight nearly 80 million yuan in the bag.

After "Chen Qing Ling", latecomers have followed suit. As of now, with the addition of "Celebrating More Than a Year", five episodes have been launched in an attempt to advance on-demand: the manga drama "Once Upon a Time There Was a Spirit Sword Mountain", users can watch the last five episodes in advance for 12 yuan; the urban romance drama "You Without Secrets" remade from "Hear Your Voice", users pay 2 yuan to watch the next episode in advance, and pay 3 yuan to unlock to the finale; the ancient costume romance drama "The Bright Moon Shines on My Heart" launched members to spend an additional 12 yuan to enjoy the last 6 episodes of the finale.

The video platform has tried to test the bottom line of users again and again. Why did "Qingyu Nian" become the "scene of a large car accident"? "Behind the scenes" believes that this is directly related to the user attributes corresponding to various dramas.

When "Chen Qing Ling" was broadcast, the reputation was not good in the first week, complaining more than praising. Later, the breakthrough in the promotion of the series was transferred to the marketing point of the two male protagonists’ appearance, attracting a large number of fans. The biggest difference between fans and fans is that the focus is on Idol itself, willing to pay for idols and regard spending money as support, which is fundamentally different from the mentality of fans who watch the show in advance.

After that, the manga drama "Once Upon a Time There Was a Spirit Sword Mountain", the remake drama "You Without Secrets", and the ancient costume romance drama "The Bright Moon Shines on My Heart" all hit the secondary payment point at the "Unlocked Finale". From the perspective of the mentality of the drama fans, spending money once can see the end, and you don’t have to worry about waiting for more, which is equivalent to solving the problem at one time.

As the popular drama "Celebration of More Than a Year" at the end of 2019, the identity of the drama chaser is relatively complex and can be roughly divided into three categories:

◆ The first is the original party. The original novel "Qingyu Nian" was first published in Qidian Chinese in 2007. It is an early work of the platinum writer China Literature Limited, and it is also its famous work. Compared with the general adaptation, "Qingyu Nian" opened with a comic and humorous style, which won the favor of many original parties, which also won the first batch of fans for the script itself.

Secondly, there is the fan club. "Celebration of More Than a Year" brings together young idol stars such as Zhang Ruoyun, Li Qin, Xiao Zhan, Song Yi, and Li Chun. Chen Daoming, Wu Gang, and other actors are blessed. They have their own fan attributes, and girls and women take it all, which coincides with "Chen Qing Ling".

◆ Finally, there are drama chasers, who belong to retail investors. Most of them come for the reputation and popularity of the drama, and the purpose is simply to watch the drama. Therefore, it is not difficult to infer that the drama chasers in "Qingyu Nian" cover a wide range of age groups, and most of them are rational drama watchers.

The video platform obviously did not understand the user. "Qingyu Nian" chose to start on-demand in the 22nd episode, which was more than half ahead of the previous drama. The so-called advanced on-demand was only to quench the hunger and thirst for a week. Even if the drama fans spent 50 yuan, they still couldn’t get rid of more suffering. For VIP users, the meaning of VIP lies in dignity, privilege, level, and identity. If you pay for the second time without prior notice, you will disregard the user’s right to know. It doesn’t matter whether you spend money or not. The key is not this truth. On the other hand, "Qingyu Nian" suffered copyright leakage, and the number of pirated episodes was more than that of advanced on-demand. For the time being, regardless of piracy violations and violations, from the choice level, it has already provided a new release outlet for drama fans. Internal and external factors are mixed together, and the video platform naturally causes fans to boycott.

"Advanced on-demand" is just the beginning?

The emergence of "advanced on-demand" is not a whim of video platforms. "Behind the scenes" understands that behind the pay-and-pay is a reflection of the difficulties and pressures currently facing video platforms.

According to official data, in 2018, the three video platforms of "Aiyouteng" lost a total of about 19 billion yuan. In 2019, the loss continued to grow. The third quarter report of 2019 released by iQIYI showed that the net loss in the quarter reached 3.70 billion yuan, an increase of 19.4% compared with the loss in the same period last year.

The losses are caused by various factors, but in the final analysis, there are problems with the business model of Internet audio-visual. As early as 2018, Yang Weidong, the former rotating president of Alibaba Entertainment, bluntly said, "If the business model is just pure advertising and membership buyout model, there is no problem with simple production, purchase and sales relationships. But as the investment in head content gradually increases, the value of content cannot be fully digested by advertising and membership alone. Video platforms will usher in a cold winter after the capital ebb."

Looking back over the past few years, under the impetus of "content is king", the copyright battle between video-based websites has become more and more intense. In the era of PC Internet video in 2013, the competition for video rights triggered a "money-burning war".

In 2013, Sohu Video spent nearly 100 million to buy the exclusive broadcast rights of "The Voice of China"; in 2014, iQIYI bought the "Dad Where to 2", "Happy Camp", "Every Day Up", "Variety Big Coffee Show" and "Let’s Date" in one breath. The copyright of the five variety shows cost close to 200 million yuan; in 2015, Tencent bought NBA exclusive broadcast rights for 5 years and 500 million dollars.

The competition of online video platforms has caused copyright fees to soar. It is understood that in 2006, the copyright fee for a single episode of "Wulin Gaiden" was 1250 yuan; in 2011, the copyright fee for a single episode of "Step by Step" was more than 700,000 yuan; in 2016, the copyright fee for a single episode of "Ruyi Chuan" was 9 million yuan… In just ten years, the copyright fee has skyrocketed by 7,200 times, which is naturally the main reason why Internet video platforms are difficult to make profits.

In the second half of 2018, salary restrictions and entertainment restrictions were introduced one after another, and the copyright cost of video platforms decreased. But new problems have come again. First, the overall slowdown in the growth rate of the industry. In 2018, the overall user growth rate of online video has dropped to 5.7%, compared with 25.5% in 2008. According to QuestMobile statistics, as of June 2019, the number of active users of online video increased by only 2.4% year-on-year, which is the lowest level in the pan-entertainment industry. Second, as the entertainment industry encounters a capital winter, advertisers have taken a conservative attitude towards the overall growth of the marketing budget of video platforms. This is undoubtedly worse for video platforms that achieve commercial closed-loop through "new user acquisition through ads" and merchant advertising.

In response to the "Qingyu Nian" advanced on-demand incident, both platforms involved gave official responses. Wang Juan, vice president of Tencent Video, said, "We have also thought about the controversy caused by" Qingyu Nian "this time, and we are still not considerate enough in our understanding of members’ notification and consumer psychology. In the future, we will further optimize and enhance the service experience of members, and bring you more high-quality content and considerate service." iQIYI also made a similar statement. Dai Ying, vice president of iQIYI and general manager of the self-produced drama development center, said, "Our original intention is to meet users’ more diverse content needs, but we may not have done a good job. In the future, we hope to take more into account users’ psychology and do a good job in the design and notification of the broadcast."

The anxiety of video platforms comes from the disparity between revenue and cost, so exploring new business growth points will become inevitable.For users, "advanced on-demand" is just the beginning. Compared with the forced buying and selling of "Qingyu Nian", the difference in the future will only be the improvement of consumer comfort.

How can video platforms earn a decent income?

The video industry is an early industry of the Internet. As early as 2005, Tudou was launched. In 2006, Youku was launched, and the industry has a history of more than ten years. At present, the companies in the first camp of the video industry include iQIYI, Tencent Video, Youku, and Mango TV, PPTV, etc. Unfortunately, these video platforms are all lossmaking.

Looking at the foreign video industry, it is a hot one. In the early morning of October 17, Netflix, the largest video platform in the United States, announced its third-quarter financial results for this year. According to the financial data, Netflix’s third-quarter revenue was $5.245 billion, an increase of 31.1% over the same period last year’s $3.999 billion. Net profit was $665 million, an increase of 65% over the same period last year’s $403 million. At the same time, in November this year, Apple TV + and Disney + were launched one after another, and Disney + gained 4 million users in the first month and received $55 million in revenue.

"Behind the scenes" Horizontal comparison found that these foreign profitable mainstream video platforms have exclusive profit models, which is also a good reference for domestic video platforms.

1) Increase the price of membership fees and make a good transition to new and old customers

Judging from the "Qingyu Nian" storm, it is not easy for members of video websites to raise prices. Netflix also encountered such a development crisis in 2014. At that time, Netflix’s approach was to divide members of different levels according to the resolution and sound effects of video signals. First, the price was raised for new high definition members, from the original $7.99/month to $9.99/month, and old users enjoyed the price of $7.99 until two years later. In this way, not only did it fully respect the existing rights of old users, but also allowed new members to enjoy better high definition services. Correspondingly, Netflix’s paid members still increased by 18.9% in 2014.

Apple TV + and Disney +, which launched in November this year, have also done their homework on the user experience. Both new services support 4K and HDR format content. The increasing technological content brings users a sense of freshness, and the membership fee increase naturally becomes appropriate.

2) Homemade content, deeply engaging users

High-quality and unique content, available only to paying subscribers, has always been a must-kill weapon for Netflix to dominate the market. Have you seen the TV series "House of Cards"? Former US President Barack Obama is said to be fascinated by it and complained that the sequel is too slow. Some even say that the plot of "House of Cards" will affect the outcome of the US presidential election. Its production and distribution company is Netflix.

How strong is Netflix’s homemade content? On December 10, 2019, at the Golden Globe Awards, known as the "Oscar weathervane", it successfully led with 17 nominations in the TV category and 17 nominations in the film category. This seems to mean that Netflix is not far from the Academy Awards for Best Picture. Spending money, throwing money, or throwing money, under the strategy of desperately making content, Netflix’s goal must not only be the Oscars. It is Netflix’s ambition to bring the film and television industry to the main track of streaming media.

Coincidentally, on December 17, 2019, the Shanghai Magnolia Awards announced that online dramas will also be able to participate in the competition from next year. This is undoubtedly a good opportunity for domestic video platforms to break through the circle and gain mainstream recognition in the industry, and it is bound to stimulate the high-quality development of online dramas.

3) Multimeson propagation to expand overseas markets

Every industry has a bonus period and a ceiling. In September 2010, Netflix took the first step in overseas expansion – entering Canada, and in the following six years, it has been deployed in more than 190 countries and regions around the world. In July this year, Netflix also extended its tentacles to India, launching a subscription model for Indian mobile phone users only 199 rupees per month. In addition, at the beginning of this year, Netflix also won the global streaming rights of "Wandering Earth" except for the Chinese mainland. Then, in April this year, Netflix announced that it had obtained the exclusive broadcast rights of Korean dramas "The Abyss", "Spring Night" and "Asda Chronicles". Netflix Chief Content Officer Ted Sarandos disclosed that Netflix’s current paying user growth is mainly from the international market.

In recent years, Netflix has also been exploring multi-meson communication, and has deployed in three OTT devices with the highest popularity of streaming media players/playback sticks, smart TVs, and game consoles. According to the latest survey data, Netflix has become the most frequently used platform on TV in the United States, surpassing traditional cable TV and cable broadcasting. Recently, Netflix also announced the lease of New York’s iconic cinema, the Paris Theater, and plans to use this location for special events, screenings, and theatrical releases of some large-scale works.

A discussion on the profit model of the video industry triggered by the on-demand model of "Qingyu Nian" is far from over. It is foreseeable that the way to increase profits should not be to pick up users’ wool, but how to improve service quality and formulate reasonable charging standards. Looking to the future, the potential of long and short video aggregation, the new opportunities brought by users’ willingness to pay, the new value generated by cross-content ecological linkage, and the vast international market will all be opportunities for the domestic video industry.

Which is better than the open source multimodal model? The TOP12 list is coming

Organize from Happy

Quantum bit | WeChat official account QbitAI

The explosion of GPT-4 has completely set off the research upsurge of multi-modal large models in academic circles.

However, how to measure the performance of this kind of model has been controversial in the industry, and there is no comprehensive evaluation standard.

In addition, there is no complete review to define and study it.

In view of this, Tencent Youtu, jointly with China University of Science and Technology and Xiamen University, published two papers on multi-modal large models.

There is not only the first multi-modal large-scale model review-

There is also a comprehensive evaluation list!

Related projects have exploded on GitHub, and as of July 3, they have already won 2200+ stars.

So, what are the best multi-modal large models in the industry at present? What are its definition, key technologies, advantages and challenges?

Let’s take a look together.

TOP12 ranking of multi-modal large models

The researchers set a total of 16 lists, including two general lists and 14 subtasks.

The overall list can be regarded as the score of the "overall ability" of the model, which is divided into perceptual and cognitive categories, and 14 subtasks are some of the subdivided tasks, which can evaluate whether the multi-modal large model is better at doing something.

The researchers selected a total of 12 open source multi-modal models to "demonstrate" the evaluation criteria.

The total list of perception categories is the total score of all perception tasks, and the display is the highest in BLIP-2:

The general list of cognitive classes is a list of various cognitive tasks, which adds up to the highest in MiniGPT-4:

The evaluation results show that BLIP-2 and InstructBLIP are in the top three in these two lists, and they are really the "top players" of the current open source multimodal model.

Specific to the 14 subtasks, the ranking of the model is different.

The evaluation results are as follows. It can be said that it is clear at a glance who is more "partial" and who can achieve comprehensive optimization in various tasks:

So, how is the score result of this list obtained?

How to get the scoring standard?

The paper holds that a good multi-modal large-scale model scoring standard should have the following four characteristics:

(1) It should cover as many areas as possible, including perception and cognitive ability (perception is the basis of cognition).

Among them, the former refers to identifying objects, including their existence, quantity, position and color; The latter refers to more complex reasoning based on comprehensive perceptual information and knowledge in LLM, including common sense reasoning, numerical calculation, text translation and code reasoning.

(2) Its data or labeling should avoid using existing public data sets as much as possible to reduce the risk of data leakage.

Therefore, all instruction-answer pairs in the evaluation should be artificially constructed. For a small number of public data sets, only their images are used without relying on their original labels. At the same time, try to collect data by manual shooting and image generation.

(3) Instruction design should be as concise as possible and conform to human cognitive habits.

Different instruction designs may greatly affect the output of models, but all models are evaluated under unified and concise instructions to ensure fairness. A good multi-modal large model should have the ability to generalize to such concise instructions and avoid falling into hint engineering.

(4) The output of multi-modal large model under this concise instruction should be intuitive and convenient for quantitative statistics.

The open answer of multi-modal large model poses a great challenge to quantitative statistics. The existing methods tend to use GPT or manual scoring, but they may face inaccurate and subjective problems.

Therefore, after the production, the final evaluation question is about this:

Then, according to the accuracy of the model answer, the score is judged.

It is worth mentioning that the authors have also tried to design multiple-choice instructions, but found that the current multi-modal large model is still difficult to follow such complicated instructions. (doge)

Summary of the first multi-modal large model

Of course, the evaluation criteria of this list are not "groundless".

To understand why the list is rated like this, you can look at another paper review on multimodal large models, which carefully sorts out its definition, key technologies and challenges.

Specifically, the paper defines the multimodal megamodel (MLLM) as "a model with the ability of receiving and reasoning multimodal information, which is extended from LLM".

Compared with the popular single-mode LLM, this model has the following advantages:

It is more in line with the habit of human cognition of the world. Human beings have multiple senses to receive multiple modal information, which are usually complementary and synergistic. Therefore, using multimodal information can generally better recognize and complete tasks.

More powerful and user-friendly interface. By supporting multimodal input, users can input and convey information in a more flexible way.

Broader mission support. LLM can usually only accomplish the tasks related to pure text, while MLLM can accomplish more tasks through multimodal, such as picture description and visual knowledge quiz.

Therefore, if you want to study this kind of multi-modal large model, you often need to master three key technologies:

1. Multimodal instruction tuning (M-IT).

2. Multimodal in-context learning (M-ICL).

3. Multimodal Chain of Thought, M-CoT).

In addition, we need to study one of its applications (multimodal system with LLM as the core), namely LLM-Aided Visual Reasoning, LAVR).

However, at present, the multi-modal large-scale model is still in its infancy, so there are also some challenges, such as limited perceptual ability, fragile reasoning chain, further improvement of command obedience ability and the widespread problem of object illusion.

New scene, new form and new mode
The exhibition service mode has been fully upgraded.
The 2021 China Mobo Fair will be innovated in an all-round way, and an industrial chain with systematic development of exhibitions, conferences, competitions, performing arts and cultural tourism ecology will be built, and multi-dimensional and multi-city scenes will be linked to expand the activity space and participation capacity.
The exhibition scene mode has been upgraded in an all-round way, and the "1+1+2+7" scene is integrated in the whole city and even the whole country. There is a main venue of Chongqing Guobo Center (Yuelai) with an area of over 100,000 square meters, a "CIMA Locomotive Park" specially built for motorcycle friends all over the country, and at least two hot pot business districts representing Chongqing characteristics, including Xi ‘an in Shaanxi, Taiyuan in Shanxi, Chengdu in Sichuan, Nanjing in Jiangsu, Changsha in Hunan, Kunming in Yunnan and Fangchenggang in Guangxi.
Therefore, combining the cutting-edge Internet technology and online display forms, we can open up online and offline interactive scenes and show the creativity and value of motorcycles in all directions. In the 5G era, we will build a benchmark for the service model of C-side exhibitions, explore new scenes, new forms and new models, and promote the development of new consumption.
As the largest professional motorcycle exhibition in China and the world, this exhibition will have more than 30,000 square meters of outdoor venues to carry out dynamic motorcycle exhibitions. The "920 Labor Knight’s Day", "CIMAMotor’s C-bend debut", "CIMAMotor’s Owner Selling" and "CIMA Motor’s Favorite Model Selection and Test Drive Experience of the Year", which are deeply loved by motorcyclists, are about to start registration or voting. This year’s newly added "Go to Chongqing for Barbecue" national motorcyclists reception area is in full swing, and more special interactive activities will be unlocked one after another, presenting the interactive participation and appreciation of motorcycles to the audience in all directions.
Among them, the "920 Labor Knight’s Day" will adopt the latest Internet technology to realize the cross-regional linkage communication of exhibition brands between Chongqing’s main venue and seven key regional sub-venue cities across the country. The sub-venue cities will not only hold special theme activities such as motorcycle and accessories product display, motorcycle riding parade and motorcycle music festival simultaneously with the main venue, but also connect with the main venue to enjoy the national motorcycle lottery.
It is reported that the value of prizes this year will continue to double on the basis of 2020, and motorcycle friends can realize "cloud gathering and cloud gathering" with motorcycle friends all over the country in their territories.
New Breakthrough of Fashion Trend Culture
Cross-border integration leads the industry to break the circle
Grasping and focusing on youth culture, fashion trends and creative design, China Mobo Fair is not only a fashion exhibition but also a cattle club, leading the new trend of fashion and entertainment in motorcycle industry, and will present a cool lifestyle with attitude to the audience, fully display motorcycle trend culture and gain insight into future consumption trends.
Stunts, please don’t try.
This year’s China Mobo Fair will deeply explore the consumer demand, and it will show the characteristics of intelligence, electrification, networking and personalization, and new products, new designs, new ways of travel and entertainment will be presented one by one. At the same time, the offline scene of this year’s exhibition will be upgraded, and the world’s first 80,000 lumen laser projection equipment will be used to create a brand-new night environment and create a phenomenal communication event; With the support of Chongqing municipal government and relevant departments, CIMA motorcycle park, motorcycle racing field and camping ground will be built for motorcycle friends all over the country, and an interactive experience in which motorcycle friends can participate extensively will be carried out.
In the era of short video communication, the online and offline scenes of China Mobo Fair are comprehensively planned and innovated, covering all kinds of motorcycle and youth trend cultural scenes.

Youxin is accused of selling accident cars and there is no after-sales second-hand car trading chaos.

  Zhongxin Jingwei Client September 29th (Wu Qilong) In December 2017, Ms. Tang’s family bought a used car through Youxinpai Tianjin Branch. After more than a month of use, the car began to have various faults. After inspection, it was found that the engine and gearbox of the car had traces of being disassembled for maintenance, which was suspected to be an accident car. Since then, Ms. Tang has embarked on a protracted road to safeguarding rights.

  "Your feedback question, Youxin used car has been accepted. After confirmation and verification, I will contact you actively within 1 working day. " Ms. Tang reluctantly told Zhongxin Jingwei that she had received hundreds of similar text messages, but there was no staff in Youxin to solve the problem. At the same time, because Ms. Tang said that she would refuse to repay the loan for this car, Ms. Tang’s family received more and more harassing calls for debt collection.

  For the problems reflected by Ms. Tang, Zhongxin Jingwei made a verification to the customer service of Youxin Group. The customer service staff confirmed that it has indeed received many complaints about the accident car, vehicle loan and loan collection from the platform about this order. However, the relevant person in charge of the public relations department of Youxin said that consumers bought cars from car dealers, and the vehicle problem had nothing to do with Youxin, which only provided financial leasing services.

  What is the problem? How can consumers protect their rights and interests when they encounter similar situations, and can the second-hand car trading platform not take responsibility?

  Buying a car | I feel that the platform service is good

  In mid-December 2017, Ms. Tang’s family took a fancy to a 2013 Buick Hideo XT used car in Tianjin Yunda used car market.

  Ms. Tang said that considering that it is only a means of transportation for the elderly to take care of their children, buying a used car is enough. During the car selection, a staff member of Yunda used car market said that if it was decided to buy this car, it would be arranged for the staff of Youxin to talk about it.

  "Then Sun Pei, a salesman wearing Youxin overalls, arrived at the scene and said that he was only responsible for business and not quality inspection. If he was not at ease, he would let his colleagues in the quality inspection department of Youxin test again. Immediately, two excellent quality inspectors arrived at the scene. After checking the car, the two said that the car was in good condition, there was no accident, and there were only a few scratches on the body. " Ms. Tang said.

  She recalled that she didn’t know much about cars and all the procedures were handled through the Youxin platform. Youxin promised to help with everything such as car loan, insurance and warranty, and felt the service was particularly good at that time.

▲ Bank card transaction details show that the down payment of the vehicle was delivered to Ms. Youxintang for the picture.
▲ Bank card transaction details show that the down payment of the vehicle was delivered to Ms. Youxintang for the picture.

  Ms. Tang also mentioned that Youxin said that due to the existence of loans for vehicles, vehicle property certificates, car purchase contracts, insurance documents, etc. must be placed on Youxin, so at present, she only has one car, one driving license and one transaction receipt for the down payment of vehicles.

  "My Youxin APP did not leave a transaction record." Ms. Tang said that the procedure was handled in the Youxinpai office of Tianjin Yunda used car trading market, and the whole process was completed offline without online operation.

  Car | Suspected to be an accident car

  After Ms. Tang paid the down payment, Youxin didn’t deliver the car directly, but it took a week to inform you to pick up the car at Youxin store (not the same Youxin store as when you saw the car). Ms. Tang said that when she picked up the car, she found a particularly deep scratch on the glass of the main cab of the vehicle, and immediately found Youxin. Because the quality inspector left a picture of the car condition when she first saw the car, she found that the car glass was intact when she checked the car.

  After confirming that the scratches on the car glass occurred during the period from the down payment to the pickup of the car, Youxin guaranteed the car and compensated the car glass and the whole car for 5000 yuan. "There is a payment record of Youxin compensation at hand. At that time, there was a problem with the vehicle, and Youxin gave after-sales protection." Ms. Tang told Zhongxin Jingwei.

  In mid-January this year, Mr. Li (Ms. Tang’s father-in-law), the owner of the vehicle, found that the fault light was always on when the vehicle was in use, and then it rattled when it started, and it often happened that the gear could not be hung and the gear could not be picked up during driving.

  Ms. Tang said that by March of this year, it was already very difficult to start the car. It was difficult to shift gears and pick gears, and sometimes it would turn off, but it could still be driven with great efforts. In March, the car couldn’t run at all.

  "At this time, we realized that the problem of vehicles may be very serious." So, Ms. Tang sent the car to the vehicle repair shop for inspection. After inspection, the master of the repair shop told Ms. Tang that the engine and gearbox of the car had traces of being disassembled for maintenance. If it was to be repaired at its own expense, it would cost more than 30,000 yuan.

  Ms. Tang suspected that this was an accident car, so she began to contact the customer service of Youxin, and every time the customer service replied, "Your feedback question has been accepted by Youxin used car. After confirmation and verification, I will take the initiative to contact you within 1 working day, but in fact there has been no reply.

  In desperation, Ms. Tang had to contact Sun Pei, the salesman of Youxin who bought the car at that time. Sun Pei told Ms. Tang that he was only "responsible for pre-sales, regardless of after-sales" and gave Ms. Tang a customer service phone number of Youxin Beijing. However, after contacting Ms. Tang, she found that the rhetoric of Youxin Beijing customer service is still "the feedback problem has been accepted and will be contacted actively within one working day", and the problem has not been solved.

  Rights protection | Multi-party contact is blocked and long

  In the case that the problem has not been solved for a long time, Ms. Tang decided to suspend the car loan in August and return it after the vehicle problem was solved. However, since the suspension of car loan repayment, Mr. Li, the owner of the car, has received dozens of harassing calls from Youxin every day. Some of the calls also threatened, "We are the collection department of Youxin, and we don’t care if the car is an accident car, but if we don’t repay the car loan on time, someone will come to collect it and confiscate your house and car."

  "Now, this car has been lying downstairs," Ms. Tang said. "We can’t drive it after buying it, and we have to pay back the loan every month. We are really anxious."

  In August, Ms. Tang finally waited until someone from Youxin took the initiative to contact her. However, Han Jiahua, a self-proclaimed after-sales person of Tianjin Youxin Airport Branch, said that in early 2018, Youxin Tianjin Company was divided into two parts, one part was Youxin Airport Branch and the other part was Youxin Yunda Branch; The car was bought in Yunda Branch, but it will be fed back to Airport Branch every time after sale. This has nothing to do with Airport Branch, so we have to go to Yunda Branch to solve the problem.

  Later, Ms. Tang came to Yunda used car market again to find Youxin Yunda Branch, but the staff said that Yunda Branch was only responsible for pre-sales, and there was no after-sales. All after-sales services were handled by Tianjin Airport Branch, and the after-sales problem of the car glass incident was handled by Airport Branch, so the after-sales problem of this car should not be solved by Yunda Branch.

  "During the period, Sun Pei also coordinated and contacted the manager of Youxin Tianjin Region and the after-sales staff of Youxin Airport Branch (colleague Han Jiahua). After consultation, they said that they would give a reply within one week." Ms. Tang added that no one contacted after waiting for half a month, but no one answered the phone when she called the staff of Youxin who participated in the negotiation at that time.

  "At this time, I was embarrassed, so I was pushed around." Ms. Tang had no choice but to get through the customer service of Youxin again, hoping that the headquarters could coordinate a person to communicate the problem. The customer service promised to solve the problem again, but there was no reply.

  On September 25th, Ms. Tang organized and published the event through Weibo and @ Youxin Xiaoer. Youxin Xiaoer replied that he had received feedback and coordinated immediately. However, Ms. Tang said that no one has contacted her so far.

  "I contacted Sun Pei two days ago, and his feedback is that there is no solution at present." Ms. Tang recently told Zhongxin Jingwei.

  Ms. Tang said that now she is complaining about customer service again, and the customer service staff even asks her, "Haven’t the problems you have reflected been solved yet? We have expedited your registration for many times, and we have expedited your handling every time. " Referring to this, Ms. Tang feels a little dumbfounding.

  Speaking of the current demands for safeguarding rights, Ms. Tang told Zhongxin Jingwei that she hoped Youxin would stop threatening and harassing by phone. At the same time, because the accident car involves the safety of use, the vehicle is afraid to use it again. I hope Youxin will return the car for a refund.

  "If the problem has not been solved, I am not going to continue to repay. After all, no one can spend tens of thousands of dollars to buy an iron knot." Ms. Tang added that on September 19, the car had been voluntarily returned to Youxin Tianjin Branch.

  Response | Youxin said that it only provides loans.

  The lawyer suggested taking legal proceedings.

  Regarding Ms. Tang’s experience, the relevant person in charge of the used car public relations department of Youxin responded to Zhongxin Jingwei, saying that Youxin was not familiar with the vehicle condition, and when buying a car, Youxin signed an exemption confirmation letter with the consumer, confirming that it was purchased from the car dealer. This car has not been tested and certified by Youxin.

  The above-mentioned public relations personnel of Youxin said that if there is a problem with the vehicle, consumers should find a car dealer to coordinate and solve it. As for the customer’s claim that there is a problem with the vehicle and the repayment obligation is no longer fulfilled, the financing company has to urge the customer to repay, including telephone calls and text messages.

  Ms. Tang does not agree with this statement. She said that after discovering the problem with the vehicle, she first called the after-sales service of Youxin and also contacted the car dealer. Car dealers said, "If you buy a car from a car dealer and Youxin only provides car loans, then the down payment should be paid to the car dealer, not Youxin."

  "Actually, the down payment was paid directly to Youxin, and Youxin tested the vehicle before buying the car, which also shows that the car was bought from Youxin, and Youxin should be responsible for the test results." Ms. Tang revealed a detail. She once asked why the vehicle insurance premium was more than 8,000 yuan. At that time, Youxin said that because the test found that the car was in particularly good condition, the valuation was set at 98,000 yuan, and the premium was calculated based on the valuation.

  At the same time, she also mentioned that at present, she can’t prove that the car was purchased from a car dealer, and the payment record is indeed in Youxin’s place. And the loan-related financing company mentioned by the public relations staff of Youxin did not know when buying a car.

  So, how should consumers deal with this situation? Qiu Baochang, director of Beijing Huijia Law Firm and president of the E-commerce Rule of Law Research Association of Beijing Law Society, suggested in an interview with Zhongxin Jingwei that after a dispute occurs, consumers can negotiate with Youxin. If negotiation fails, they can complain to the market supervision department and consumer protection organizations. If it still can’t be solved, you can take legal proceedings to protect your rights. If Youxin doesn’t respond all the time, consumers can also take civil proceedings directly.

  Qiu Baochang further pointed out that if the negotiation is not good and mediation is impossible, we will go to court through legal procedures, and the law will collect evidence and divide responsibilities. If there is evidence to prove the original car’s promise of no accident, and now it is found to be an accident car, we can consider whether it is suspected of fraud. For the temporarily pressed contract and vehicle property certificate, you can claim; When faced with telephone threats, it is a more appropriate way to choose the police.

  In fact, in recent years, incidents of selling faulty cars in the used car market have occurred frequently. How to standardize this problem and resolve the credit crisis of second-hand car market transactions? Cui Dongshu, secretary-general of the National Passenger Car Market Information Association, suggested that, first of all, information technology should be used to increase transparency. It is necessary to improve the second-hand car trading system, establish a national unified second-hand car quality traceability system, strengthen the monitoring of second-hand car quality, and disclose relevant information to consumers to avoid information asymmetry between consumers and e-commerce platforms; Secondly, it is necessary to increase the penalties imposed by the regulatory authorities on corporate advertising, urge enterprises to fulfill their information disclosure obligations to consumers, fully respect consumers’ right to know, choose, fair trade and security, and safeguard consumers’ rights and interests.

Microsoft’s first AI PC is coming, so be wary of AI hardware’s "making up the number".

The PC market is very lively these days.

Apple released the first MacBook Air with M3 chip in the form of a press release, and declared that it was "the world’s best consumer laptop for AI" and ran into the AI PC track.

Since the birth of computers, Microsoft and Apple have been old enemies. In the AI era, the two giants pointed their fingers at Maimang. Microsoft and Apple have successively entered the $3 trillion club in terms of market value, and you are chasing after me. At the same time, Microsoft is determined to win the highest voice on AI PC. At the software system level, Microsoft has the trump card of OpenAI, and Copilot launched at the application level has become a global top-stream AI model application. Today, Microsoft’s first AI PC hardware is coming.

After being cut off by Apple, Microsoft’s first AI PC came.

According to the exclusive news of Windows Central, Microsoft will release a new generation of Surface Pro(Surface Pro 10) and Surface Laptop(Surface Laptop 6) on March 21st, 2024. As the first "AI PC" in Microsoft hardware, these two new Surfaces will be the first devices in the market to support Windows 11 "Next Generation AI", which shows that Microsoft attaches importance to these two new Surfaces.

1fcf5a8220231117041117.jpg

Although Microsoft has not announced the specific configuration of these two new computers, considering that Microsoft has repeatedly emphasized the AI performance of these two hardware, it is not difficult to guess the hardware configuration of these two computers:

As the benchmark of Microsoft notebook computers, Surface Laptop 6 and Surface Pro 10 will use the latest Core Ultra processor like other AI PC with high probability. Considering the memory requirements of NPU and Arc Graphic, Surface is expected to break away from the era of 8GB RAM and set 16GB memory as the initial configuration of Surface Laptop 6 and Surface Pro 10.

Considering the overall design idea of this year’s notebook computer, Surface Laptop 6 may also switch to a narrow border design, and follow the new specification of Microsoft, and change the Windows logo key on the right side of the keyboard to the Copilot key.

In addition, Microsoft also mentioned that these two computers will have "comparable performance to iPad Pro and MacBook Pro", and we can’t rule out the possibility that Microsoft will introduce ARM based processors into the Surface Laptop product line. In connection with Microsoft’s "platform" behavior for the X Elite processor during the Snapdragon Summit in 2023, it is not difficult to see that X Elite will also appear in the Surface series sooner or later.

a1ef00476d58403d8688734e3cd910d0.jpg@0-109-1619-971a.jpeg

However, according to Qualcomm’s schedule, the X Elite version of Surface may not be available until the middle of the year. In the case that the ARM based system itself needs additional adaptation, can the X Elite version of Surface, which has lost its first-Mover advantage, overtake Ultra in AI applications? This question needs to be answered by Microsoft and Qualcomm.

If the release dates of Surface Pro(Surface Pro 10) and Surface Laptop(Surface Laptop 6) are really like March 21st, then we have reason to believe that Apple’s eagerness to release the MacBook Air M3 chip version may be a "cut-off". If it is released until the spring conference, Apple’s AI PC Virgo may "crash" with Microsoft’s original AI PC.

This reminds Xiao Lei of the way in which in 2023, a few days before the release of Vision Pro, the cheaper and more mature Quest 3 was first released. Afterwards, Andrew Bosworth, Meta CTO, said that the company "chose to release Quest 3 in June" based on consumers’ shopping habits instead of worrying about Apple’s competition-I believe you are a ghost. It can only be said that the business war of the giants is so unpretentious.

AI hardware is surging, and more and more people are making up for it?

On the other hand, even though X Elite and Ultra processors are fundamentally different in architecture, considering that both platforms have NPU for running local AI, Microsoft’s AI applications are still at the application layer at present, and Microsoft has mentioned on many occasions that its AI is a "mixed model" (local+online model), Lei boldly guesses here that the comprehensive performance of the AI applications launched by Microsoft in the future will not be much different between the two platforms.

Then the question follows: since most AI applications are still at the application layer at this stage, does it mean that as long as the PC can provide sufficient computing power and drive specific AI application layer use cases, this PC can be regarded as an AI PC?

Or in a more refined language: where is AI PC?

I know, this question looks very simple: the computer that can use AI is naturally AI PC. However, as far as the current progress of the AI industry is concerned, the development progress of hardware and software in the AI field does not match: as early as 2016, the AI model was applied to mobile phone images, and the AI technology applied to PCs can be traced back to Watson launched by IBM in 2011.

OpenAI, which became famous overnight because of ChatGPT, also used "traditional PC hardware" to develop an AI model that caused Internet giants to "panic". Can these HPC clusters that develop and run the latest AI models be called AI PC?

f4529fbde84c4324b2a7dfda00872a33.png@180-127-3152-1892a.jpeg

Image source: Microsoft

Different from the "5G mobile phone" and "game notebook" determined by hardware differences, all kinds of AI use cases that stay at the application layer decouple the "AI use case" from the "hardware" to a certain extent: AI use cases do not need to pay attention to the computing power from HPC cluster, Tensor or CUDA core, NPU or remote high-performance server, so long as the model can run smoothly, this device can be regarded as the so-called "AI device".

Obviously, this way of distinguishing "AI devices" depending on whether the device can run the AI model will bring many problems: brands no longer need to devote themselves to research and development, as long as they change the name of the machine learning algorithm around 2010, they can openly call themselves "AI devices".

Take mobile phone brands as an example. Some brands just rename the new features provided by Android system every year. What’s more, only the simplified model of speech recognition is imported into the device locally, and then all the instructions of users are thrown to the HPC cluster running the AI language model at the far end, and then they flaunt their AI capabilities.

This is also the reason why I have always hated the name "AI device": as long as the model is concise enough, any hardware with basic computing power can be called "AI device". When all devices can be called AI devices, "AI" will be completely reduced to marketing vocabulary like graphene, quantum and metauniverse.

This is obviously not the AI era we want to see.

AI hardware is imperative, what is the real AI PC?

In my opinion, if we really want to expand the influence of AI in digital products, we should replace AI model with AI use cases: shift the definition standard of whether it belongs to "AI hardware" from whether it owns exclusive hardware and runs AI model to "whether AI can bring new experiences".

On the mobile phone, we should no longer worry about whether the speech recognition function of the mobile phone input method uses a brand-new AI model, but focus on whether this "black box" (users don’t need to know the running logic behind it) can bring users a brand-new experience, such as learning users’ phonemes locally and answering calls for users with simulated user’s original voice.

We don’t need to pay attention to whether the AI model of a Wensheng graph is a device-side machine learning model or a remote server model. Instead, we pay attention to how this model can be integrated into the daily application of mobile phones in a functional way, such as automatically generating and replacing wallpaper according to the user’s text description.

The same is true for AI PC. Take Microsoft’s Copilot as an example. Traditionally, users need to tell the computer which tasks to perform through specific commands or clicks. However, with Copilot, computers will be able to participate in the workflow more actively, and predict and execute tasks in advance by understanding users’ intentions and habits. For example, when dealing with documents, Copilot can automatically put forward suggestions for improvement based on users’ past editing habits, and even help write and organize content.

In addition, Copilot can greatly improve the efficiency of information retrieval and management. Copilot can quickly extract key information from different data sources and make intelligent summaries for users. This is undoubtedly a great boon for professionals who need to deal with a lot of information. In the daily file management, Copilot can also help users organize and search files more effectively, and can quickly locate or classify documents through language instructions, which greatly saves time and energy.

In other words, the focus of "AI hardware" should not be what hardware can do, but what computing power and access port hardware can provide for local, cloud or hybrid models running on devices, and what future AI hardware is allowed to achieve. Computer technology, including AI, is a process of continuous self-denial and iteration, which means that the software strongly bound to equipment has fallen behind the industry since its release.

In other words, only by "platformizing" computing power can AI equipment catch up with the ever-changing AI era.

Zhao Ming, CEO of Glory, once shared Glory’s views on AI mobile phones in media interviews. I think the views are worth learning from all brands that emphasize their "AI device" attributes at this stage:

I think many manufacturers have great misunderstandings about AI mobile phones. Many people call the ability to provide generative AI on mobile phones AI phones. What is the core provided by mobile phones equipped with generative AI? Calculate power. As long as you provide the computing power, this program can have a variety of massive applications through the computing power of your platform. The ability of this generative AI should be a variety of applications provided by many AI service providers in the future.

I can link AIGC to ask a few questions in my notebook, "Write me a novel", and it becomes an AI notebook? You just provided a platform and display for calculating power and taking notes.

[Strugglers are young, first-line stories] Teng Chao: Seven years of grinding a sword to break through the "stuck neck"

  [Strugglers are young, a first-line story]

  Guangming Daily reporter Party Wen Ting Yan Shenghe

  "The photoresist sample is eluted from the chromatographic column to determine the degree of crosslinking and molecular weight, using the separation mechanism of size exclusion." Teng Chao, a young distinguished professor, is explaining the experimental principle to students in the laboratory of Applied Technology Research Institute of Shenzhen Vocational and Technical College.

  Don’t underestimate the dimly lit laboratory behind him. Although the area is small, every piece of equipment inside is a "treasure" cherished by Teng Chao. In June this year, it was in this tens of square meters laboratory that the photosensitive polyimide photoresist was developed. Through testing and verification, its performance can meet the import substitution requirements.

  Teng Chao is in the laboratory. Bright picture

  From research and development to success, Teng Chao and his team have been studying this project for seven years. Compared with the traditional photoresist, this new photoresist not only plays the role of lithography but also is a dielectric material, which can greatly shorten the working procedure, improve the production efficiency, and make the important raw materials in China’s chip manufacturing supply chain self-controllable.

  Although the scientific researcher is young, he is accurate and neat when facing the team, and his gestures reveal calmness and steadiness. This Ph.D. major in polymer physics is engaged in the research of new materials. What made him successful in this field of pursuing speed?

  The story began 10 years ago, on the eve of graduation from Nanjing University, when a company came to the door and wanted to conduct joint research and development, so that Teng Chao really understood the current situation faced by China’s photoelectric display and semiconductor industry at that time. "There are a bunch of source technologies behind the screen that are still being ‘ Get stuck in the neck ’ For example, the LCD spacer microsphere material that accurately controls the thickness of the liquid crystal layer has been available for nearly 40 years, but the technology and supply are still in the hands of Japanese companies. "

  This made Teng Chao make a bold decision — — Go to Shenzhen, the nearest to the industry, to engage in applied technology research! Teng Chao told the most respected teacher Xue about this idea and got the support and encouragement from the teacher.

  Teacher Xue in Teng Chao’s mouth is an example that has the deepest influence on his scientific research. As one of the first doctors in the field of polymer in New China, he often warns Teng Chao, "Don’t stare at the data in research, don’t just want to send papers, but produce more useful results for the industry".

  When Teng Chao first challenged the LCD spacer microsphere project, he encountered unprecedented difficulties.

  "I can also supplement the technical problems through a lot of reading and experiments. The most difficult thing is to form a team." It turns out that this project is to develop alternative materials rather than breakthrough products, so it is difficult to publish papers, so it is difficult for the research group to recruit people. From doing experiments, collecting data to analyzing and testing, Teng Chao and his partner personally started, "almost lived in the office for more than a year."

  Where there’s a will, there’s a way. In the process of cramming lessons and sweating, the interdisciplinary knowledge network gave Teng Chao a "light stroke". He designed a set of algorithms to accurately control the variables in the experiment, and finally succeeded: several factories tested at the same time, and all of them passed at one time for the first time.

  This is also the first related product in China that can fully pass the flat panel display industry test and have mass production capacity, breaking the Japanese long-term monopoly in this field for decades. Now all the major domestic flat panel display manufacturers use this high-precision microsphere material with high cost performance.

  The success of microsphere research and development has given Teng Chao and the team great encouragement and confidence. In 2015, Teng Chao turned his attention to photoresist, a key material that troubled chip research and development. This kind of material is used for circuit packaging and lithography opening of the core part of the chip, which is monopolized by Japan and the United States and banned from domestic enterprises in many fields.

  Many enterprises have a hard time saying — — The shelf life of photoresist is only 6 months, so it can’t be stored in large quantities. Long-term technical monopoly has created a "seller’s market". This monopoly is not only reflected in the final product, but also in the raw materials of the product.

  "Take the photosensitizer at the core of photoresist as an example. We need high-purity photosensitizers. There is no supply in China, and Japanese companies refuse to supply them after learning about their purchasing intentions." Recalling the development process, Teng Chao’s face showed a wry smile. "We found that there was no shortcut to raw materials, so we had to set up a new R&D team and start to tackle the synthesis method and purification process from the various components of photoresist."

  The project team started with raw chemicals that can be supplied in large quantities in China, and finally got high-purity photosensitizer products and other raw materials that meet the needs of the project step by step. "Although this has lengthened the research and development cycle of photoresist, the establishment of domestic industrial raw material supply chain has completely freed us from being ‘ Get stuck in the neck ’ The possibility. "

  "Apply what you have learned and the industry will serve the country." Today, Teng Chao, like his mentor, often exhorts dozens of doctoral and master students in the team. In such an atmosphere, the team attacked one after another "stuck neck" industrial pain points: liquid crystal orientation agent, hardened insulating layer material, electroacoustic sound quality enhancement material.

  "When tackling key problems in scientific research, we should not only consider commercial value, but also consider whether it contributes to the country, society and industry." Teng Chao said firmly, "We must master the key core technologies in our own hands!"

Long-distance vehicles are deeply integrated with Hanma Technology, and Geely re-plans its commercial vehicle business.

The whole pattern of China’s automobile market has undergone tremendous changes. In the passenger car market, the revolution caused by electrification and intelligence has made China automobile enterprises enjoy the dividend in the window period. Geely, Great Wall, BYD and other traditional China brands and Weilai, Tucki and ideal new power brands have grown strongly; In the commercial vehicle market, greater changes are brewing.

In 2020, the domestic production and sales of commercial vehicles were 5.231 million and 5.133 million respectively, up by 20.0% and 18.7% respectively. Compared with the negative growth of passenger cars, the commercial vehicle market began to enter an explosive period of growth.

It is precisely because of this that Geely has made bold acquisitions and layouts in the field of commercial vehicles. On the basis of developing long-distance vehicles, it has taken Hanma Technology into its pocket and occupied a strong position in the domestic heavy truck market. What will happen to Geely’s commercial vehicle sector after the acquisition is completed? Where is the target locked?

Long-distance automobile and Hanma science and technology should be integrated

In July 2020, Geely Commercial Vehicle acquired 15.24% equity of valin star horse. In November 2020, valin star horse was renamed Hanma Technology. In May 2021, Geely Commercial Vehicle Group further increased its capital to Hanma Technology. After the capital increase was completed, Geely Commercial Vehicle Group’s shareholding in Hanma Technology increased from 15.24% to 28.01%.

The acquisition is only the first step. Next, Geely Commercial Vehicle’s new energy brand Long-distance Vehicle and Hanma Technology will be integrated and developed. Recently, Fan Xianjun, president of Geely Commercial Vehicle Group and chairman of Hanma Technology Group, made it clear at the 2021 National Partner Conference of Hanma Technology and Long-distance Vehicle that "Hanma Technology and Long-distance Vehicle are integrated and develop together."

Long-distance automobile and Hanma technology are integrated according to the situation. Why do you say that? At present, the industry development environment in which commercial vehicles are located has become more and more obvious. In Geely’s view, the future development trend of the industry is becoming more and more clear. It has become an irreversible and inevitable trend for the industry to replace traditional fuel vehicle products with a new generation of commercial vehicles with green and intelligent technologies as the core. The head effect is based on the consensus of the future trend, and the two sides have reached cooperation and started the coordinated development of integrated advantages and complementary advantages.

Among them, the long-distance automobile has formed two major product technical routes: the urban commercial vehicle system with pure electricity and extended-range power system as the core, and the road commercial vehicle system with methanol clean energy and charging and replacing technology as the core. The production bases are arranged in Nanchong, Sichuan, Shangrao, Jiangxi, Zibo, Jinzhong, Anhui, Maanshan and Huzhou, Zhejiang, and the products cover all commercial vehicles such as passenger cars, light trucks, LCV and heavy trucks. In the first half of this year, the overall sales of long-distance vehicles increased by 626% year-on-year.

Hanma Technology is an important R&D base for heavy trucks, heavy special vehicles, core components and new energy commercial vehicles in China. From January to July, 2021, Hanma Technology ranked first in sales of new energy heavy trucks, with a cumulative increase of 418.2% year-on-year and a market share of 21.32%.

After the strong integration, Remote Auto and Hanma Technology will complement each other in product and positioning, and develop together, positioning the heavy truck business strategy as "the leader in building green intelligent transportation solutions".

Enter the first echelon of heavy trucks in 2030.

According to the planning of Geely Commercial Vehicle, Hanma Technology locates the mainstream strong brand of heavy trucks, develops diversified products and diversified power, and will further enrich the product spectrum in the future and become the most comprehensive brand of heavy trucks. Products in the tractor, dump trucks, trucks, special vehicles, new energy vehicles for a comprehensive layout. Power has also been diversified. In addition to traditional diesel engines, there are LNG engines, methanol engines and power exchange systems.

Another big brand of long-distance cars is positioned as the leader of new energy heavy trucks, making efforts in new energy and intelligence. In terms of products, new energy products are laid out on traction, dump trucks and special vehicles; Power will continue to exert its strength in power exchange, hydrogen fuel cells and methanol.

Each has its own strengths and integrated development will be the future development direction of Geely’s two major heavy truck brands. Therefore, long-distance vehicles and Hanma Technology will fully integrate their product resources in the future. "In the long run, Hanma and remote product planning must be a common platform, and the comprehensive integration of product resources is accelerating." According to Fan Xianjun, "We focus on the iterative development of products, that is, we are selling a generation, researching a generation and planning a generation. Therefore, we periodically plan G1 products that comprehensively enhance our competitiveness, G2 products that are being optimized and developed in various systems, and G3 products that are fully competitive in the future market."

Behind a series of actions, Geely’s ambition in the field of commercial vehicles was also exposed. At present, Geely commercial vehicles have planned to complete a three-step leap from 2020 to 2030, and the integration period will be from 2020 to 2022, with the goal that the market rate of heavy truck products will reach 3%; The breakthrough period is from 2023 to 2025, and the annual sales volume of heavy trucks is 56,000 units, accounting for 5% of the market, ranking among the top 8 in the industry.

According to the plan, by 2030, the annual sales volume of Geely’s heavy trucks will reach 100,000, entering the first echelon.

Geely has been planning for commercial vehicle business for a long time, and now it is time to show its action. It remains to be seen whether the strategic objectives of each stage can be realized.
