A few days ago, Chongqing football ushered in a brand-new professional league team, which is Chongqing Tonglianglong, which gathered many old Lifan generals. After the dissolution of the Chongqing team, Chongqing Tonglianglong began to play in the China Champions League and began to carry the banner of reviving Chongqing football. Chongqing Tonglianglong performed well in the Champions League last season and got the qualification of Chong B. After Chongqing Tongliang Dragon rushed to China B, it filled the gap that there was no professional team in Chongqing football.

Chongqing lifan used to be a strong football team in China, and it also performed well in the Super League, and once beat Evergrande. Chongqing team has also trained international players like Zhang Chiming and Feng Jin. Unfortunately, before the Super League started last season, the team once again encountered the crisis of unpaid wages. Finally, after comprehensive consideration, Chongqing team decided to quit professional football. Chongqing team quit professional football, which made Chongqing football lose its professional team.

At the critical moment, Chongqing Tonglianglong stood up, started to play in the China Champions League in a team, and recruited the Chongqing football flag Wu Qing. Chongqing Tongliang Dragon has now rushed to China B, attracting the attention of a group of old Lifan generals. Chongqing Tonglianglong can consider introducing Liu Huan whose contract with Guoan expired. After leaving Guoan, Liu Huan went to Dalian for trial training.

Whether Liu Huan can stay in Dalian is a huge unknown. Because Liu Huan’s Dalian team is in a precarious state. Dalian team doesn’t even have the qualification to introduce new aid. If this problem is not solved in the future, Liu Huan will not be able to complete the registration. Therefore, Liu Huan can consider returning to Chongqing. At the same time, Chongqing Tonglianglong chose to play a warm-up match in order to test the training results during this period.

Chongqing Tonglianglong chose to play with Qingdao Manatee, a new Chinese Super League army. Originally, fans thought that Chongqing team would be played by Manatee. Unexpectedly, the Chongqing team was very tenacious in the game and finally defeated its opponent 1-0. The strong play of Chongqing team in the warm-up match made the fans see the hope of rushing to armour. I look forward to Chongqing Tonglianglong’s steady and steady progress in the Chinese B League and achieving the goal of rushing to the first division in the new season.

Recently, the hottest topic in the science and technology circle is "ChatGPT". However, ChatGPT is only an external manifestation, and what deserves more attention is the development of AI technology behind it and its future application.

Some people even describe the changes brought by ChatGPT optimistically: Before ChatGPT, AI was only a module of existing scene products at most. Then, after ChatGPT, AI will redefine the product framework of existing scenarios.

Whether it is as optimists say remains to be seen, but whether autonomous driving, as one of the important scenes of AI landing, will have further development in this wave has still aroused many people’s discussion.

Some people think that autonomous driving needs more graphics, images and data processing ability, requires higher image algorithm, and has little correlation with natural language processing ability. It is not possible to realize autonomous driving with ChatGPT’s ability at present.

Of course, some people think that the appearance of ChatGPT shows us a possibility, that is, trained AI will make high-level autonomous driving expected to appear in a few years.

Why does the progress of AI technology make people pay attention to whether autonomous driving is affected?

Observing the development history of autonomous driving, it is not difficult to find that every major breakthrough of autonomous driving is synchronized with the development of AI technology.

We know that,AI is actually imitating the brain neural network and learning some very humanized skills by analyzing a large amount of data.In 1980s, the first practical application of neural network happened in the field of automatic driving.

In 1987, researchers at Carnegie Mellon Artificial Intelligence Laboratory tried to make a truck that could drive automatically. They manually write codes for all driving behaviors and write as detailed instructions as possible for various situations encountered by trucks on the road, so as to make the vehicles run automatically. But unfortunately, this way can only make the car achieve a speed of several inches per second.

Manual code writing failed, and another doctoral student named Dean pomerleau chose another way: neural network.

He named his system ALVINN. After adopting this system, trucks use the images taken by the roof camera to track what drivers are doing, so as to observe how to learn to drive on the road. In 1991, ALVINN drove from Pittsburgh to Erie, Pennsylvania at a speed of nearly 60 miles per hour.

However, a more direct and broader impact occurred in 2012.

Jeff Hinton, a professor at the University of Toronto, and two of his students, Alex Krzyzewski and Ilya Satsky, won the first prize in the ImageNet image recognition competition, and published a paper introducing the algorithm AlexNet. This paper is not only the turning point of artificial intelligence, but also the turning point of global technology industry.

As the key technology of autonomous driving, target detection and image recognition are highly benefited from the breakthrough of computer vision algorithm. Therefore, with the recognition accuracy of Li Feifei team, director of Stanford Artificial Intelligence Laboratory, surpassing humans for the first time on ImageNet open data set in 2015, autonomous driving, as one of the most important landing scenes of AI, has also entered the fast lane of development.

So, will the appearance of ChatGPT become the Milestone of autonomous driving again?

Generally speaking, AI can be divided into three parts: voice, vision and natural language understanding.The last wave of AI was mainly based on the breakthrough of visual image recognition technology, and this time ChatGPT is a natural language processing technology based on GPT-3 model, which can effectively simulate human language understanding ability, thus helping people better understand and analyze natural language text data.

When we want to discuss what impact ChatGPT will have on autopilot, we think that we should first find out whether autopilot here refers to mass-produced low-level autopilot (assisted driving) or high-level L4 autopilot. Secondly, does ChatGPT refer to a language model or a more generalized generation model?

From the perspective of natural language understanding, ChatGPT has a more direct impact on human-computer interaction in the assisted driving part, but it may not have a great impact on L4-level automatic driving.

Cui Dongshu, secretary-general of the Federation, also wrote in his WeChat WeChat official account that the innovation of human-computer interaction and intelligent cockpit system is very strong, especially the human-computer interaction ability of domestic car companies is very strong. Only China enterprises can understand Chinese more deeply. With the empowerment of the bottom layer in the future, the domestic automobile industry will have more good human-computer interaction effects at the application level.

For example, by using ChatGPT, the vehicle can interact with the driver by voice or text, and provide the driver with real-time feedback on vehicle status and driving information.

Before this, although a large number of in-vehicle interactive systems have appeared, the pain point of the industry mainly focuses on the "understanding" part, and most of the in-vehicle voice interactive systems are not intelligent in "understanding", resulting in a single function and command word of the whole system. ChatGPT’s explosion made the market see the hope of solution.

However, Cui Dongshu, secretary-general of the Federation, also said that,Electrification is the core of new energy vehicles, and intelligence is just icing on the cake. In the future, the core competitiveness of car companies will still be to build electric vehicles, and at the same time make full use of intelligence such as ChatGPT to empower the development of the automobile industry.

Of course, whether it is the core or not, it is not enough to have a technological breakthrough if you want to get on ChatGPT. An AI industry person told Titanium Media that "there are still cost issues, including the use cost, cloud service cost and targeted training cost."

However, from a broader generative model, the generative model with big data and large parameters will help to achieve a higher level of autonomous driving.

He Xiang, a data intelligence scientist at Mimo Zhixing, said in an interview with Titanium Media App that the vehicle-side capabilities mainly include two categories: perception and cognition. The perception ability really relies mainly on image technology, while the cognitive ability relies more on similar generation technology of ChatGPT.

That is to say,ChatGPT’s revolutionary significance lies in: letting AI model enter the era of knowledge and reasoning. At present, the biggest shortcoming of autonomous driving lies in the lack of sufficient intelligence in decision-making planning.

ChatGPT uses a training method called "Human Feedback Reinforcement Learning (RLHF)", and He Xiang, a data intelligence scientist at Mimo Zhixing, explained to Titanium Media APP.GPT is a large-scale universal pre-training language model. GPT1, GPT 2 and GPT 3 mainly improve the parameter scale, while ChatGPT mainly introduces human feedback data for reinforcement learning.

The introduction of this method can ensure the minimum output of useless, distorted or biased information according to human feedback in training.

It happens that there is also a kind of automatic driving decision algorithm called imitation learning, which is to let the machine learn how human drivers do it in different scenarios.

Generally speaking, every takeover by a human driver is an artificial feedback to the autonomous driving strategy; This takeover data can be simply used as a negative sample, which is a record that the autopilot decision is corrected. At the same time, it can also be used as a positive sample to improve cognitive decision-making

"The big model of big data and big parameters can learn more potential knowledge, including different environments and different scenarios, which is equivalent to learning a lot of common sense of autonomous driving. This common sense is very important for autonomous driving decisions." He Xiang, a data intelligence scientist at the end of the year, told Titanium Media App.

That is to say,In the process of autonomous driving research and development, the idea of human feedback reinforcement learning can be used to train a model to verify and evaluate the output of the machine model, so that it can make continuous progress and finally reach the driving level of human beings.

Therefore, it can be said that the improvement of basic ability has brought about the expansion of imagination and applicable scenarios. However, at this stage, we still can’t accurately judge how much change the big model represented by ChatGPT will bring to autonomous driving. An industry person told Titanium Media App that the excellent generalization ability trained by the big model may make there no corner case in the world.

Corner case refers to a small probability event that may occur during driving, but the frequency is extremely low. Although it is rarely encountered at ordinary times, it is likely to lead to a fatal traffic accident when encountering a corner case that cannot make a decision for an autonomous driving system.

The emergence of ChatGPT has made the industry realize that it is possible to gain a higher level of autonomous driving technology by constantly accumulating kilometers and running like this.

In fact, before this, both foreign Tesla and domestic Tucki, Baidu and Mimo Zhixing were already exploring the route of "big model".

In 2020, Tesla announced that it would introduce a large model based on deep neural network into its autonomous driving, and now it has realized a large-scale public beta of pure visual FSD Beta; Tucki expressed the viewpoint of using large models to get through the whole scene of XNGP on the 1024 Science and Technology Day in 2022. Baidu Apollo believes that the Wenxin model will be the core driving force of the elevator’s automatic driving ability.

As early as 2021, Mimo Zhixing announced that it would improve its data processing ability with the help of a large model. On February 17th this year, Mimo Zhixing officially upgraded the large model of human driving self-monitoring cognition to "DriveGPT", which will continue to introduce large-scale real takeover data, and continuously improve the evaluation effect through intensive learning of human driving data feedback. At the same time, it also uses DriveGPT as a cloud evaluation model to evaluate the driving effect of small models at the vehicle end.

However,The development of high-level self-driving cars is a complex multidisciplinary field, involving a wide range of technical and regulatory challenges. The progress of artificial intelligence technology can bring some impetus, but this is not a short-term problem.

It is reported that GPT3.0 involves 170 billion parameters, with more than 300 GB of memory, and the training process costs more than 12 million US dollars. The above-mentioned industry insiders said that the autopilot algorithm is to run in the car. Can such a large model be deployed to the car? How much computing power does it need to support? In addition, autonomous driving can not be completed by repetitive and simple road data stacking, so how to ensure a large amount of data is also a key issue.

A year’s plan lies in spring, and the spirit of the start is seen.

After the Spring Festival in the Year of the Rabbit, Oaks has made great efforts to innovate, improve quality and empower industries, strengthen market expansion, and greatly increase orders to achieve a good start. From the roar of machines, from the busy work of assembly lines, and from the enthusiasm of employees, Oaks has shown great vitality.

On the one hand, Oaks actively supplements talents in all aspects through spring recruitment activities; on the other hand, it injects new kinetic energy into the high-quality development of the whole year with the attitude of improving quality and increasing efficiency in future factories and waiting for no time.

As a leader in the manufacturing industry, the high efficiency, high standard and high precision of Oaks products have always been recognized by the industry. The digital, intelligent and standardized "future factory" is the mystery of Oaks to improve quality and efficiency. With the accelerated integration of the new round of scientific and technological revolution and industrial transformation, the new generation of information technologies such as 5G communication, big data, cloud computing, Internet of Things and artificial intelligence are constantly changing the production mode of Oaks and accelerating its high-quality development.

In the future factory of Oaks, from the core motor to sheet metal, assembly and logistics, Oaks Air Conditioning Factory adopts intelligent manufacturing almost all the way. It only takes 38 seconds to get from a plastic pellet to an air conditioning panel, and the production efficiency of the factory is improved by 30%, and the proportion of intelligent products is 80%. This set of data is enough to illustrate the hard core speed of Oaks’ "intelligent manufacturing".

The intelligent future factory can not only improve the production efficiency, but also make the production process more refined and reasonable. Through the intelligent management of production, the production process and equipment are fully interconnected to realize real-time monitoring of production process and equipment operation, and can be pushed in real time through mobile APP to realize mobile management and mobile office, which can greatly improve efficiency.

In addition to the intelligence of the production process, the future factory of Oaks has also realized the intelligence of planned production scheduling, rate monitoring and comprehensive efficiency of equipment, and through the collection and utilization of big data, the efficiency of quality inspection is also very obvious, for example, through 5G+AI vision technology, it has changed the dilemma of low efficiency and difficult traceability of surface quality detection by manual naked eyes. Once the product surface has scratches, differences in color brightness and other defects, even if it is thinner than hair, the camera will not let go. The detection system will digitally calculate the defective image, compare it with the standard, and feed back the defects at the first time with the help of 5G communication technology, so as to take immediate improvement measures. This is equivalent to installing intelligent quality inspection eyes in the production process, which is a great contributor to product quality improvement.

The improvement of efficiency also means the reduction of cost. Oaks relies on the intelligent production of future factories. Traditionally, the assembly line needs more than 100 people. Now it is all completed by machines and conveyor belts, and only three workers are needed, which undoubtedly saves the cost greatly.

On the whole, with the help of digitalization and intelligent empowerment, Oaks has achieved remarkable results in optimizing production efficiency, improving product quality and reducing production costs, so that it has enough strength to cope with a more complex competitive environment and write a new chapter in development.

Knowing that there is a long way to go for development, john young is just breaking the waves. Oaks keeps pace with the times, making a good start, laying a good foundation and opening a good game for the whole year with an efficient future factory. In the future, Oaks will further accelerate the pace of upgrading intelligent manufacturing, keep up with the development speed of the times, and strive to run out of acceleration on the intelligent track.

March is destined to be an extraordinary month for football in China. According to Li Xuan’s report, in March, Du Zhaocai, deputy director of the General Administration, who is currently taking over the Football Association, will retire at the age of 64, and he will also step down. This also means that the new head of the Football Association must be implemented in March, otherwise Gao Zhidan’s words will become empty talk.

The time is short and the task is urgent. Where can we find the new head of the Football Association? In fact, this problem is not difficult. At present, the Football Association has three most suitable candidates. In addition to talking about three suitable candidates, we must talk about Sun Jihai, which has been popular recently, because it has delivered seven Xinjiang players for U20 men’s soccer team, and because of the outstanding performance of U20 men’s soccer team captain Effeldin, Sun Jihai is considered by many fans to be the most suitable to be the head of the Football Association, but in fact, Sun Jihai and Fan Zhiyi are the same. Although they are all members of the subordinate provinces of the Football Association, it is almost impossible to enter the consideration of the head of the Football Association.

Why? As the head of the Football Association, the first condition is to be able to accept the Football Association quickly. Chen Wharf dared to let a layman take office because he was surrounded by Gao Hongbo and Sun Wen. However, after this failure, according to the report of Football Daily, the General Administration is more inclined to let people within the system who understand sports take this position.

Who is the most suitable candidate at the moment? In fact, the first two suitable candidates are the two current vice presidents of the Football Association. The first one is Gao Hongbo. The advantage of Gao Hongbo is that he has been a vice president for a long time, and he is very familiar with the work of the Football Association, especially the administrative work, and can almost seamlessly connect with the current work.

The second candidate is Sun Wen. Sun Wen’s advantage here is that she is a woman. Sun Wen has led the women’s football team to achieve excellent results and accumulated enough fame over the years. Of course, the most important thing is that Sun Wen has not had much contact with the Chinese Super League team, which can also avoid the recurrence of Chen Wharf and Shanghai Harbour.

Who is the third candidate? The third candidate may be the most unexpected person for the fans. He turned down Li Xiaopeng, who works for the men’s soccer team. In fact, Li Xiaopeng is now the most likely to become a dark horse. Why? According to the report of Football Daily, there are several criteria for the General Administration to select the next head. The first one is between 40 and 50 years old, because this age can lead the Football Association to have a sustainable development time. Li Xiaopeng is now 47 years old, but Sun Wen and Gao Hongbo are both over the standard.

The second is that the General Administration is biased towards people within the system, so that it can be bound. Compared with Gao Hongbo and Sun Wen, only the identity of the Football Association, Li Xiaopeng is the deputy director of the Football Management Center of Shandong Sports Bureau, and the level has come to the deputy hall. Li Xiaopeng is more in line with the identity of the former two. The third is to know sports. Li Xiaopeng has been a coach of the club and the national team. Coupled with his experience as a player, Li Xiaopeng definitely has a chance to turn into a dark horse.

The picture comes from the Internet. If it is infringing, please contact to delete it.

On December 1st, Beijing time, the NBA regular season in the 2021-22 season was fighting. In a battle of focus today, the Sun will face the Warriors at home. Prior to this game, the Warriors 18 wins and 2 losses first ranked first in the league, and the Sun team ranked second in the league 17 wins and 3 losses. Therefore, this game was particularly attractive.

According to statistics, this is the first time that the NBA history has appeared more than 85%of the winning percentage, and it is in a team confrontation between the 7+ consecutive victory. The Warriors have achieved a 7 -game winning streak, and the Sun team has won the longest 16 -game winning streak this season. If the Suns can win again today, they will tie the team history of the longest consecutive victory.

Before the start of the game, the Suns officially released the preview map of the game, as well as warm -up maps such as Paul and other generals.

It can be seen that although this game can tie the long -winning record of the team history and whether they can defeat the Warriors’ top leagues, the Sun team will still be very relaxed. Paul, Booker, Claude and other people will laugh at the training ground.

The Warriors officially wrote: "The duel of the best record team of the two league, staged in Phoenix tonight!"

ESPN also debated this game. However, the result was one side, and everyone thought that the Warriors could win. Former NBA star Reydick said: "The warrior has a greater probability of winning the game, their defense is very good, they will take a lot of defense. The main tactics of the sun are to relieve it by the pick -and -roll, and then go to the ball three points. Unless Paul and the" Booker can play ultra -efficiency, otherwise it will be difficult for them to win. "

The reasons for the well-known commentator A-Smith is only one reason for the Warriors, that is Curry. He said: "I am not interested in this issue, because the Warriors will win the championship, and no one can defeat them. The Warriors will win bigger today, but the Sun team will win when they meet next time. Because they do not have Curry, Curry is the greatest shooter created by God. And the Warriors’ ball -free running and transfer balls are the top leagues. They are the purest basketball. "

Whether this game continues 17 consecutive victories, or the Warriors defend the league 1, we will know the answer in a few hours.
