Analysis on Data Requirements of End-to-end Intelligent Driving

Intelligent driving technology is striding towards the end-to-end direction, and its technical iteration affects the nerves of the whole intelligent driving industry. From the overall structure, the end-to-end technical route can be divided into global end-to-end and modular end-to-end.

Global end-to-end is simply divided into two categories: world model and VLM.Usually, the parameter scale is very large, and the global end-to-end generalization ability is stronger.,Agent has strong interactive understanding.

Modular end-to-end and traditional algorithm approximation,Auxiliary modules can be added at will to easily cope with traffic rules constraints; The end-to-end consumption of modules is relatively low, and the generalization ability is weak.

In fact, modular end-to-end is the mainstream of end-to-end that is close to landing at present, and a few enterprises are studying the overall end-to-end.(Tesla may have used a global end-to-end, but there is very little public information; Weilai plans to launch the world model). In China, Huawei ADS 3.0 is recognized as the leading intelligent driving system. Its technical route is modular end-to-end.

Huawei ADS 3.0 architecture

This paper analyzes the requirements of end-to-end technology for data from the industry, mainly involving dataScale, quality, diversity, real-time and closed-loop feedbackAnd so on.

End-to-end intelligent driving relies on deep learning models, which usually requireenormous dataConduct training. Tesla relies on millions of cars equipped with cameras and sensors around the world to continuously collect driving data to train the FSD(Full Self-Driving) system. In the financial report, Musk once mentioned the data needed for the training model: "One million video trainings are barely enough; 2 million, slightly better; 3 million, you will feel "wow!" ; When it reaches 10 million, it becomes unbelievable. "

Tesla data engine framework (From the network, small hidden drawing)

ask：

  • Millions to billions of kilometers of data, covering different weather, lighting, road conditions, traffic flow and other complex environments.

High-quality data is very important for end-to-end learning, especially labeled data. Traditional autonomous driving (such as Waymo) usually relies on high-precision maps and accurately labeled 3D point cloud data. Tesla and domestic OEMs are abandoning high-precision maps and turning to the "visual priority" strategy, requiring neural networks to understand the environment end to end. Relying on automatic labeling system to reduce manual intervention and improve data quality. Automatic labeling can replace 5 million hours of manual work, and manual work only needs to check and fill in a very small part.

ask：

  • accuracyMismarking data may lead to learning deviation and affect security.
  • Denoising: Filter sensor errors and low-quality data (blur, occlusion, etc.).
  • consistencyThe data of the same scene at different time points should be reasonably consistent for network generalization.

From the perspective of the whole industry,It is a new trend to improve data quality through self-supervised learning technology.. NVIDIA has improved the efficiency and reliability of data annotation through EmerNeRF’s self-supervised learning technology.

EmerNeRF decomposes scenes by introducing three neural fields: static field, dynamic field and flow fields, so as to realize effective learning of complex scenes.

EmerNeRF decomposes and reconstructs pipelines.

Static field is responsible for labeling static elements such as buildings, signs and street lamps, while dynamic field expresses all moving objects, while flow field simulates the motion of dynamic objects and is used for dynamic feature aggregation in time. Most importantly, EmerNeRF can learn these scenes automatically from raw data without any manual annotation. After learning, the model can present the temporal and spatial changes of the scene at the same time, and then realize the high-fidelity reconstruction of static scenes and dynamic objects. Through this technology, it can help mass production enterprises to further improve the training volume and gain more opportunities in end-to-end autonomous driving.

The end-to-end model needs to deal with the complex and changeable driving environment, so the data must have a wide range of scene coverage:

  • Geographical diversitySuch as cities, highways, rural roads, mountainous areas, etc.
  • weather condition: sunny, rainy, snowy, foggy, etc.
  • Difference of traffic rulesDifferent countries and regions have different traffic regulations, signs and driving habits.
  • Long tail sceneExtreme situations (sudden intrusion of pedestrians, crossing of animals, sudden accidents, etc.) are often the difficulties of autonomous driving. Tesla uses "shadow mode" to capture these cases and use them for training.

ask：

  • For global vehicles, it is necessary to collect global data, covering different cultures and regulations.
  • Reinforcement learning pays special attention to the "long tail problem" data to avoid the failure of the model under Corner Case.

Since Tesla FSD entered China in 2025, many institutions have evaluated it. According to their feedback, the performance of FSD in China is moderate, although the basic driving ability is excellent.However, there are many defects in traffic light recognition, traffic rules compliance and mixed traffic scenes.. The main reason for this situation is the influence of data diversity differences. (FSD basically does not use China road traffic data to train the model. )

Intelligent driving system needscontinuous renewalData to adapt to the new driving situation. When there are many test vehicles, it is necessary to filter, compress and transmit valuable scenes efficiently. Tesla’sThe FSD Beta version adopts a fast iteration strategy.Its data pipeline can automatically discover and collect "valuable cases" to improve the model. The characteristics of end-to-end learning determine that it is more dependent on real-time data feedback. For example, when the model is wrong in a specific driving environment, the system needs to quickly recover data, analyze problems, and update the model through OTA.

ask：

  • Data collection, processing, training and deployment should have high efficiency.
  • Through automatic scene identification and screening mechanism, scene data can be distilled efficiently and effective data can be obtained quickly for model training and evaluation.

The core advantage of end-to-end driving lies in data-driven closed-loop learning.

  • Application of shadow mode: Even if ADS doesn’t really take over driving, the system can still run in the background and record.Model decision vs. Difference of human driver’s decision.If the deviation is found, the scene data will be returned and used for model optimization.

  • Data enhancement and simulationTesla, NVIDIA, Weilai, Xiaomi and other companies use neural networks to generate Neural Rendering, while Waymo and other companies build large-scale virtual test scenarios for model fine-tuning.

Tesla trained the model through simulation.

High confidence synthetic virtual scene (aiSim)

ask：

  • data mining: Automatically identify low performance areas and improve the convergence speed of the model.
  • Simulation ability: Using high fidelity analog data to improve data utilization.

andThe requirements for data are extremely strict, including:

  • Large scale data: covering millions to billions of kilometers of driving data.
  • High quality labeling: Reduce manual intervention and improve the accuracy and efficiency of labeling.
  • Scene diversity: Covers various road conditions, weather, geographical environment, etc.
  • real-time: Quickly collect, analyze, optimize and update OTA.
  • closed loop feedback: Automatically discover problem data and optimize the model.

　　The fourth is to improve the management system of teachers in modern universities and stimulate the innovative vitality of teachers.

　　Improve the employment mechanism of college teachers. Fully implement the autonomy of employing people in colleges and universities, and the relevant government departments do not uniformly organize the employment examination for college personnel, simplifying the entry procedures. In accordance with the relevant provisions of the state and the actual needs of running a school, colleges and universities independently formulate the employment conditions of teachers and recruit teachers openly. The graduation institution, study experience abroad, study methods, papers and patents shall not be taken as restrictive conditions. Strictly control the selection and employment of college teachers, and implement the dual inspection of ideological and political quality and professional ability. Establish a system linking the pre-job training of new teachers with the qualifications of college teachers. Broaden the channels for selecting and employing people, and increase efforts to attract outstanding talents from domestic and foreign industrial enterprises and professional organizations. According to the requirements, complete and optimize the team of teachers and counselors of ideological and political courses in colleges and universities. Explore the employment experience and social practice experience of industrial enterprises as important conditions for hiring professional teachers in vocational colleges. To study and introduce measures for the appointment and management of foreign teachers and standardize the management of foreign teachers.

　　Speed up the reform of post management of college teachers. Actively explore the implementation of the total staff management in colleges and universities. Colleges and universities adopt diversified employment methods according to law to employ people flexibly, make good use of compilation resources, give priority to ensuring the demand of teaching and scientific research, and tilt towards key disciplines, characteristic disciplines and important management positions. Reasonably set the proportion of post structure of teaching staff and strengthen the construction of staff. We will further promote the post employment reform, implement the post tenure system management, further explore the management methods such as the combination of quasi-employment and long-term employment, and implement and improve the employment mechanism that can be promoted and demoted, and can enter and exit.

　　Strengthen the management of teachers’ education and teaching in colleges and universities. Improve the teaching quality evaluation system, multi-dimensional evaluation of teaching norms, teaching operation, classroom teaching effect, teaching reform and research, teaching awards and other teaching achievements. Strengthen the proportion of teaching achievements and the effectiveness of teaching and educating people in performance distribution, job title evaluation and employment, and post promotion assessment, and take a certain amount of undergraduate (specialized) teaching as a necessary condition for the promotion of teachers’ titles. Taking professors as the basic system, colleges and universities should make it clear that professors should undertake the minimum class hours requirements for college students, and those who fail to meet the requirements will be given unqualified annual or employment assessment.

　　Promote the reform of the professional title system of college teachers. Study and introduce the guiding opinions on the reform of the professional title system of college teachers, and delegate the right of professional title evaluation directly to colleges and universities, which will independently evaluate and appoint them according to their posts. Improve the evaluation criteria for teachers’ professional titles, set evaluation indicators according to different disciplines and different post characteristics, and determine evaluation methods. The study experience abroad, the number of patents and the index requirements for indexing, inclusion and citation of papers are not restrictive conditions. Improve the evaluation mechanism of peer experts and carry out the evaluation of representative achievements. Explore the introduction of contribution evaluation mechanism for teachers who undertake national defense and key core technology research tasks. Improve the process of professional title evaluation, and continue to do a good job in the supervision of professional title evaluation of college teachers.

　　Deepen the reform of the evaluation system for college teachers. Highlight quality orientation, pay attention to evaluating teachers according to their ability, performance and contribution, resolutely reverse the tendency of neglecting teaching and educating people, and overcome the disadvantages of focusing on papers, hats, titles, academic qualifications and awards. Standardize the use of indexes related to papers such as SCI in colleges and universities, avoid the absoluteness in the use of citation data such as SCI, SSCI, A&HCI and CSSCI, resolutely abandon "judging papers by journals" and get rid of "SCI first" in papers. Reasonably set the evaluation cycle and explore long-term evaluation. Pay attention to the combination of individual evaluation and team evaluation. Establish a hierarchical feedback mechanism for assessment results. Establish a linkage mechanism of college evaluation, undergraduate teaching evaluation, subject evaluation and teacher evaluation policies, and optimize and adjust the evaluation indicators that restrict and influence the implementation of teacher evaluation policies.

　　Establish and improve the management system of part-time teachers and part-time teachers. On the premise of performing their duties on campus and not affecting their own jobs, college teachers may, with the consent of the school, take part-time jobs that are closely related to their own disciplines and can give full play to their professional abilities. Localities and universities should establish and improve the management system of teachers’ part-time jobs, standardize teachers’ reasonable part-time jobs, and resolutely punish teachers’ part-time chaos. Encourage colleges and universities to hire off-campus experts and scholars as part-time teachers, improve the management measures for part-time teachers, standardize the selection and employment procedures, clarify the standards, responsibilities, rights and work requirements of part-time teachers, and ensure that part-time teachers have high professional ethics, professional ability and educational level.

　　The fifth is to effectively protect the treatment of college teachers and attract stable first-class talents to teach.

　　Promote the reform of salary system in colleges and universities. Implement the income distribution policy oriented to increasing knowledge value, expand the autonomy of salary distribution in colleges and universities, and explore the establishment of a salary system that conforms to the characteristics of colleges and universities. We will explore the establishment of a system for investigating and comparing the salary level in colleges and universities, improve the mechanism for determining and increasing the salary level in colleges and universities, reasonably determine the salary income level of college teachers on the basis of ensuring the normal adjustment of the basic salary level, and increase the inclination to colleges and universities with high-level talents and heavy teaching and scientific research tasks. The cash reward for the transformation of post scientific and technological achievements obtained by college teachers according to law is included in the total performance salary of the unit in that year, but it is not limited by the total amount and is not included in the total base. Implement policies and regulations such as salary and income distribution incentives for high-level talents, part-time and part-time salary, and starting a business after leaving the post. Encourage universities to set up professorships funded by third parties.

　　Improve the incentive mechanism of internal income distribution in colleges and universities. To implement the autonomy of internal distribution in colleges and universities, colleges and universities should improve the internal income distribution mechanism and performance appraisal methods in combination with the actual situation, and tilt towards teachers who are rooted in the front line of teaching and have outstanding achievements, teachers who have undertaken urgent and dangerous tasks and made outstanding contributions, and teachers who are engaged in basic frontier research, national defense science and technology and other fields. Take part in teaching and research activities, write textbook cases, undertake the task of proposition invigilation, and guide students in graduation design, employment, innovation and entrepreneurship, social practice, student associations, competitions and performances, etc. into the workload. Encourage excellent teachers to undertake the teaching work of continuing education, and bring the relevant workload into the performance appraisal system. Do not directly link the quantitative indicators of scientific research such as the number of papers, patents, projects and project funds with performance salary distribution and rewards, and give full play to the incentive-oriented role of income distribution policy.

　　The sixth is to optimize and improve the talent management service system and cultivate a group of high-level innovative talents.

　　Optimize the talent introduction and education system. Strengthen the strategic orientation of serving the country, strengthen the top-level design of the talent system, give full play to the leading role of major national talent projects, strive to build a high-level innovation team, and cultivate a group of scientists, discipline leaders and young academic talents with international influence.

Strengthen the construction of talents in philosophy and social sciences and high-end think tanks in colleges and universities, and gather and train a group of famous teachers in philosophy and social sciences. Adhere to the correct orientation of talent flow, encourage colleges and universities to establish industry self-discipline mechanism and talent flow consultation and communication mechanism, and give play to the role of talent work alliance in colleges and universities. Resolutely put an end to the illegal introduction of talents, and those who leave relevant units and posts within the support period without the consent of the competent department of talent planning will be disqualified from the title of talents and corresponding support.

　　Scientific and rational use of talents. Give full play to the role of talent strategic resources, adhere to the correct orientation of talent use, promote the reform of talent evaluation mechanism by classification, promote the return of all kinds of talent "hats" and talent titles to honor and academic essence, avoid repeated support of similar talent plans, select people according to their posts, and determine their salaries according to their posts, and do not take talent titles as restrictive conditions for undertaking scientific research projects, job titles, appraising awards and degree points. Create an academic environment that encourages innovation and tolerates failure, and leave enough exploration time and trial and error space for talents to carry out research. Strict management of talents after employment, strengthen the assessment of contract performance and role play. Strengthen the care and service for talents, and effectively solve their practical difficulties in work and life.

　　Seventh, fully support the growth of young teachers and cultivate a new force in higher education.

　　Strengthen the training support for young teachers. Encourage colleges and universities to expand the number of postdoctoral recruits and take postdoctoral staff as an important source of supplementary teachers.

Young teachers in colleges and universities must have at least one year’s work experience as counselors, class teachers and other students, or work experience in teaching, helping the poor, and participating in foreign aid exchanges between Confucius Institutes and international organizations.

　　Solve the worries of young teachers. Local governments and universities should strengthen overall coordination, guarantee those who meet the guarantee conditions of public rental housing according to policies and regulations, and at the same time, effectively solve the housing difficulties of young teachers through various ways such as developing rental housing, revitalizing and tapping the existing resources in schools, and granting subsidies. Encourage various ways to improve the treatment of young teachers and ensure that young teachers focus on teaching and scientific research. Encourage colleges and universities to cooperate with social forces and the government to set up kindergartens, primary and secondary schools to solve the problem of young teachers’ children entering kindergartens. Pay attention to the physical and mental health of young teachers and care for them.

　　Eighth, strengthen job security and ensure that all policy measures are effective.

　　Improve the organizational security system. Taking the construction of high-quality teachers as the basic work in the construction of colleges and universities, strengthening the main responsibility of schools, and improving the working mechanism of unified leadership and overall coordination of party committees, with teachers’ work, organization, publicity, personnel, educational administration, scientific research and other departments performing their respective duties and cooperating.

China’s first ＂self-service intelligent security inspection channel＂ was opened at Guangzhou Baiyun Airport.

　　Jin Yang Network News reporter Tang Heng and correspondent Airport Xuan reported: Have you seen the automatic security check? On 25th, Baiyun Airport opened a "self-service intelligent channel" in Terminal 1 security area B, which is the first security channel in China to integrate all self-service equipment into the same channel, which means that China civil aviation security is about to enter a new stage. Yangcheng Evening News reporter learned that the self-service intelligent security inspection channel will save more time for passengers. It is estimated that each intelligent channel will be able to check 20%-30% more passengers every day.

　　The passage is located in the No.9 passage in the security check area B of the departure hall on the third floor of the T1 terminal of Baiyun Airport. It is self-help and intelligent all the time, and the passage is also equipped with a "re-inspection robot". Passengers can successfully pass through two self-service gates with their boarding pass (including electronic boarding pass) and ID card. The system automatically compares the passenger’s identity information with the ticket information, which takes less than 10 seconds to add up, saving half the time compared with manual inspection. After passing through the gate, passengers still need to put their belongings in the basket for X-ray inspection, and sensitive items such as computers, iPad and charging treasures need to be taken out separately. Subsequently, passengers can pass through the millimeter-wave security door, and the instrument will automatically scan to determine whether there are foreign objects all over the passenger’s body. If not, passengers can pass quickly; If yes, the approximate location of the item will be marked on the instrument screen, and the security inspector will conduct targeted re-inspection.

　　If there are suspected illegal items in the carry-on baggage, they will be automatically diverted to the unpacking desk by the system, and the security inspector will open the bag for inspection, and then re-examine the relevant items after taking them out.

Nongfu Spring is a little hanging？ It was reported that deforestation in the national park to extract water, and the official notice came

　　CCTV News:Recently, a video claiming that Nongfu Spring was building water in Wuyishan National Park without approval and destroying vegetation circulated on the Internet. In response, the Wuyishan National Park Administration organized an investigation team from the National Park Law Enforcement Detachment, the Forest Public Security Bureau, the Ministry of Ecology and other departments to go to the scene to verify the situation. And issued a notice on the evening of January 12.

Now what? It is 19:28 on January 11, 2020, and they have been working here, and they are still working here at night. I feel it is my duty as a citizen to report such a situation.

　　It was only after the fact that it was allocated to the park, and the deforestation situation has been investigated

　　The construction site in the video is the water intake point of Nongfu Spring, but it is not within the scope of Wuyi Mountain National Park and is more than 50 meters away from the park boundary.

　　The construction party built a construction access road of about 150 meters near the water intake point. The construction time was October 2019. At that time, the area where the access road is located was not included in the national park. It was not until December 25, 2019 that the "Wuyishan National Park Master Plan" approved by the Fujian Provincial People’s Government transferred the area of this access road to the national park. Other original roads have not been widened, refurbished or damaged along the way.

　　Regarding the destruction of forest trees during the construction of the access road and whether it has been approved, the Wuyishan Forest Public Security Department has filed an investigation on November 18, 2019. It is still under investigation.

Huawei released the M5 intelligent driving version of AITO, starting at 279,800 yuan.

Beijing News Shell Financial News (Reporter’s promise) On April 17th, Huawei held a press conference and released the M5 advanced intelligent driving version (hereinafter referred to as "intelligent driving version").

Wang Zhigang, Minister of Science and Technology： China deploys vaccine research and development according to five technical routes.

CCTV News:The State Council Information Office today (June 7) released the white paper "China Action against COVID-19 Epidemic" and held a press conference to introduce the white paper.

Wang Zhigang, Minister of Science and Technology, in response to a question from a reporter in Reuters, pointed out that since the outbreak of the epidemic, all countries have paid close attention to the vaccine problem. The white paper also includes the related contents of scientific and technological support against epidemic, such as how to combine scientific research such as drugs and vaccines with clinical first-line treatment practice, and how to use big data and artificial intelligence to support against epidemic. As far as the vaccine itself is concerned, judging from the understanding of human response to the epidemic in history, the vaccine is still the fundamental strategy for us to defeat COVID-19 virus at present. All countries put the development of vaccines in a very important position in the fight against COVID-19. But at the same time, we should also see that vaccine development is a very rigorous and complicated scientific activity, which is very difficult and has a long cycle. At the same time, because it is a scientific research, it also has great challenges and uncertainties. Some scientists compare the rigor of vaccine development to an accurately rehearsed dance, rather than an impromptu performance that can be displayed after the curtain is lifted. Therefore, safety, effectiveness and accessibility must be placed in a very important position in vaccine development. Vaccine development has played an important role in human history, but some vaccines have also gone through some detours.

疫苗成功的标志，最重要的是坚持安全、有效和可及。从科学研究上讲，疫苗研制一般要经过病毒分离、实验室疫苗构建、细胞试验、动物试验、临床研究，然后才是规模化生产，最后要经药监部门注册批准才能上市应用。我国按照五条技术路线部署疫苗研发，包括灭活疫苗、腺病毒载体疫苗、重组蛋白疫苗、减毒流感病毒载体疫苗以及核酸疫苗。在疫苗研制过程中和今后的临床试验应用，这两个方面都要加强国际合作。前期我们在整个疫苗研制过程中，都开展了很多国际合作，中国的科学家和其他国家的科学家，都是为了应对疫情，都希望在卫生健康方面为人类命运共同体作出贡献。下一步，中国疫苗如果完成了研制和临床试验后，可以达到应用的时候，我们会认真落实国家主席习近平在第73届WHO大会上的承诺，把它作为公共产品向全球提供。
