  Cctv news(Reporter Xu Hui) The Hutuo River, which originated at the foot of Taixi Mountain in fan shi, Shanxi Province, runs out of Taihang Mountain in the west and runs to the sea in the east, is the largest river flowing through Shijiazhuang City and is known as the mother river of Shijiazhuang.

  In recent years, Shijiazhuang has vigorously promoted the ecological restoration project of Hutuo River. Among the living environment examples of Hebei Province in 2016-2017, the Hutuo River Ecological Corridor Project in Shijiazhuang is on the list. The content of "treating the ecological environment like life, coordinating the management of landscape, forest, field, lake and grass system" put forward in the report of the 19th National Congress is reflected here.

  However, a few days ago, a video of "sewage facilities are put into display and sewage is discharged into the Hutuo River" was circulated on the Internet and attracted the attention of many netizens.

  At about 13 o’clock on May 4, CCTV reporters came to the video shooting place — — Longquan Gu Village, Huaishu Town, Jinzhou City, near the bank of Hutuo River, was investigated.

  4 million pretreatment equipment intermittently "strikes"

The picture on the left shows the picture in the network video, showing that there is sewage flowing out of the main gate. The picture on the right shows the picture taken by the reporter on May 4, showing that water flows out from one side of the main gate. According to the relevant personnel of Jinzhou Branch of Shijiazhuang Environmental Protection Bureau, the water treated by the pretreatment pool should flow into the Hutuo River from the side of the main gate.

According to the relevant personnel of Jinzhou Branch of Shijiazhuang Environmental Protection Bureau, the water treated by the pretreatment pool should flow into the Hutuo River from the side of the main gate.

  It is understood that the netizen who filmed and uploaded the video of "sewage equipment is decorated and sewage is discharged into the Hutuo River" is Zhou, a villager in Longquan. The video was filmed a few days ago.

  The reporter arrived at the scene of the video shooting and found that the treated water flowed from the underground pipe network to the front of the main gate, with a small gate on the front side and a water outlet on the east side behind the main gate. There are a row of pretreatment tanks on both sides of the gate, and the two pretreatment tanks are connected by pipes. Before the water reaches the gate, it flows into the pretreatment pool from the small gate, and flows into the Hutuo River from the water outlet on the other side of the gate after the pretreatment pool turns around.

  Compared with the video released by Zhou, it can be found that the water flowing out of the underground pipe network in the video flows directly into the Hutuo River from the main gate without passing through the pretreatment pool.

  Liang Ma, a staff member of Jinzhou Branch Office of Shijiazhuang Environmental Protection Bureau, said that according to the design of the sewage outlet, what the reporter saw was normal operation, indicating that the water had been treated by the pretreatment tank.

  It can be seen that the pretreatment pool does not run intermittently.

  The standard water is polluted in the 12km underground pipe network.

According to the real-time monitoring by the environmental protection department, it reaches the first-class A standard.

  The reporter found in the square on the south side of the sewage outlet of the Hutuo River in Jinzhou City that two black cars were parked here, one with the words "official car" printed on it, and four men were waiting here. Seeing the reporter taking pictures, three men came forward to ask the reporter about his origin. After identifying the identity of the reporter, the reporter was taken to Jinzhou No.2 Sewage Treatment Plant.

  According to Ji Chao, deputy director of the plant, on December 28th last year, Jinzhou signed an agreement with Beijing Sander Environmental Engineering Co., Ltd., and Sander Company won the right to operate Jinzhou Sewage Treatment Plant for 30 years.

  Ji Chao led the reporter to the outlet of the factory, and the reporter found that the purified water was clear and translucent. The treated water is discharged into the underground pipe network and flows to the sewage outlet of Hutuo River. "We have online monitoring equipment installed here, which operates 24 hours a day and automatically transmits monitoring data to Shijiazhuang Environmental Protection Bureau every two hours. The water flowing out from here can meet the first-class A standard and meet the specified requirements. "

  The data provided by the online monitoring website of Shijiazhuang Environmental Protection Bureau also shows that the monitoring data of the first and second sewage treatment plants in Jinzhou City are qualified.

  Then, why on earth is the water that has reached the standard turbid again and reddish brown when it is discharged into the Hutuo River?

  Environmental protection department: investigate the pollution sources of underground pipe network

  It is understood that the water treated by the first and second sewage treatment plants in Jinzhou City will be discharged to the sewage outlet of Hutuo River through a 12-kilometer underground pipe network.

  Wang Limin, director of Jinzhou Branch of Shijiazhuang Environmental Protection Bureau, said that the branch had found that there was a difference in water quality between the sewage treatment plant outlet and the Hutuo River outlet, and it was suspected that the qualified water was polluted in the underground pipe network. Professionals have been hired, and the 12-kilometer underground pipe network will be investigated in the near future.

  According to Wang Limin, on April 20th, some people reported that the manhole covers of underground pipe networks in the south of Qidi Village and the north of Baishui Village in Jinzhou City were lost, and unknown vehicles dumped waste liquid at night. Law enforcement officers of the Environmental Protection Bureau found a large number of rut marks on the scene, and there were traces of waste water on the ground, with obvious odor. The dumped waste liquid was discharged to the main discharge port of Hutuo River.

  At present, the public security organs have filed an investigation.

  Pretreatment tank is "unable to directly degrade industrial enterprise wastewater"

  When the water source is polluted again, can the pretreatment tank play a purification role?

  According to Liang Ma, the average daily sewage treatment capacity of the first and second sewage treatment plants in Jinzhou is 2200-2300 cubic meters and 40000 cubic meters respectively.

  The pretreatment tank of Hutuo River sewage outlet, which was built in September 2015 with an investment of 4 million yuan, is used to further improve the water quality index of effluent from sewage treatment plant. Special high-efficiency physical and chemical flocculant is added in the pretreatment tank, which can further degrade the pollutants in the water body after contacting with water, reduce the suspended solids content in the water, and ensure that the water quality flowing into the Hutuo River reaches the standard.

  The reason why the pretreatment tank is built under the sewage treatment plant and before the water flows into the Hutuo River is because this technology is based on the sewage treatment plant’s standard discharge. "If this technology is used in this kind of water produced by industrial enterprises, it should not work." Liang Ma said.

  As for the intermittent shutdown of pretreatment tank, Wang Limin, director of Jinzhou Branch of Shijiazhuang Environmental Protection Bureau, said that further investigation would be made.

Give 100 thousand! Can undergraduates do scientific research well?

  At the beginning of August, Zhang Chenyang, a senior student in Tsinghua University, received a notice from the college that he would participate in the selection of the Young Students’ Basic Research Project (hereinafter referred to as the Young Students’ Project) of the Natural Science Foundation of China on August 22, and he could choose any topic as long as the basic research related to natural science was concerned, and the project cycle was one or two years.

  As the most important funding channel for basic research in China, the National Natural Science Foundation of China (hereinafter referred to as NSFC) brought undergraduates into its talent funding system for the first time, which attracted attention. In late August, the National Natural Science Foundation of China held the first evaluation meeting of young students’ projects in Beijing and Hefei. As a pilot, outstanding undergraduates from eight universities including Peking University, Tsinghua University and China University of Science and Technology (hereinafter referred to as China University of Science and Technology) were recommended to participate in the interview.

  China News Weekly learned that up to now, the evaluation and selection of this project has been completed, and those who pass the selection can get a research fund of 100,000 yuan. According to official website, the Intelligent Research Laboratory of the Chinese University of Science and Technology, an undergraduate student in the laboratory has received relevant funding. When the project was first announced, it once aroused doubts in the scientific community: Do undergraduates have enough ability to do scientific research?

  Who can get funding?

  Zhang Chenyang is an undergraduate of the first "Strong Foundation Program" in Tsinghua University, which was launched in 2020 to select students with excellent comprehensive quality or top-notch basic research. Shortly after entering school, Zhang Chenyang, with the encouragement of his tutor, tried to carry out a scientific research project in the field of ancient building restoration that he was interested in. He spent half a year researching and experimenting, and as the first author, published the research results of this project in the domestic core journal Journal of Geotechnical Engineering. This experience opened a new world for Zhang Chenyang. "This result made me very satisfied, and I began to feel that the process of doing scientific research and solving problems was very interesting, which was very different from learning in class."

  During his school years, he participated in many projects to support undergraduate scientific research, such as Tsinghua University’s "Academic Research Promotion Plan for College Students" and "Spark Plan", and the national training plan for college students’ innovation and entrepreneurship. In July, 2021, after the extreme rainstorm in Zhengzhou, Zhang Chenyang decided to turn to the research on flood forecasting and early warning. This is also the theme of Zhang Chenyang’s application in this young student project.

  Over the years, the Natural Science Foundation of China has built a funding chain for talent projects, including "excellent youth", "outstanding youth" and innovative research groups, but the funding targets are all scholars engaged in scientific research. Putting the talent funding port ahead is a new reform of the Natural Science Foundation of China this year.

  In May this year, the NSFC had a preliminary idea. In June, Dou Xiankang, Party Secretary and Director of the NSFC, led a team to Tsinghua, Peking University and other universities for investigation. In an exclusive interview with China Newsweek at the beginning of July, Dou Xiankang mentioned that during their investigation, they noticed that there are indeed some undergraduates who have spare capacity in learning and have interest and talent in scientific research. He has also seen some students who have completed their four-year courses in just one and a half years, thus having more time to do research. Judging from the law of talent growth, early discovery and targeted training of outstanding young talents will help them stand out as soon as possible and make great progress in the future, and also provide "flowing water" for building a high-quality basic research talent team.

  The speed of the project is beyond many people’s expectations. In July, the project for young students was formally established, and in August, the Natural Science Foundation of China organized a meeting review. "We completed all the evaluation work before the end of August, in order to complete the project establishment and funding in September, so that students can start the project at the beginning of the new semester and invest in the project research." Dou Xiankang said.

  Dou Xiankang said that at present, the project is still in the pilot stage, and the Natural Science Foundation of China hopes that the scope will be smaller, so the model of "recommendation+evaluation" will be adopted, and all students participating in the evaluation will be selected by universities according to relevant requirements. At the same time, however, in order to provide excellent students with opportunities for training and support, there is no quota limit for judging, and applicants with excellent performance can get financial aid. On August 22nd, Zhang Chenyang went to the office building of NSFC to participate in the selection. He noticed that there were about thirty or forty students from Tsinghua and Peking University.

  The selection of undergraduate programs is different from the projects of "Jieqing" and "Youqing" of the Natural Science Foundation of China. According to reports, in the evaluation of young students’ projects, students should show their projects within the specified 8 minutes and answer experts’ questions within the remaining 17 minutes. Dou Xiankang once mentioned to China Newsweek that there is no need for college students to present scientific research results like "Jie Qing", and the questions raised by some students may not be mature, but the judges can generally see whether the students have a solid scientific foundation and enthusiasm for science — — This is an essential quality for scientific research.

  Pan Xin, Dean of School of Aviation Science and Engineering, Beihang University, is one of the experts in the evaluation of young students’ projects. He condensed the criteria for judging students into one: whether students have the ability to ask questions. In the question-and-answer session, he will discuss with the students why he did this topic. The question is raised by himself or his tutor. "Perhaps most students have jointly raised questions after discussion with their tutors. After all, they are still young and have to attend classes. It is not easy to do this in a short time in a brand-new field."

  Pan Yi told China News Weekly that most of the students who participated in the evaluation were sophomores and juniors. He remembers that some students studied urban planning and management, used new tools to do big data analysis of regional economic heat, and evaluated regional economic vitality. "This is a social science topic, but it impressed me deeply. In the process of students’ migration from the field of partial management to the direction of mathematics and physics, new problems in cross-cutting fields were excavated." There is also a student who studies the stability of gravitational wave antenna device, hoping to solve the problems in the existing technology by designing new engineering and software.

  In addition, unlike the previous project review, the Natural Science Foundation of China suggested that the judges discuss with the students by means of communication rather than defense, "to inspire and guide them as much as possible and stimulate their interest in scientific research". When Pan Yi communicates with these children, he can feel that they all have a good theoretical foundation, but they also need more and wider academic exchange opportunities.

  When Zhang Chenyang applied for related scientific research projects before, he was mostly asked about the professional knowledge of the project, and the tutors in the school mostly communicated with him about the details of the plan. At the review site, seven or eight experts from the audience raised about 10 questions, including basic knowledge, research experience, scientific research plan, etc., and some teachers gave him suggestions on research ideas. "I want to study the early warning of mountain torrents in North China, and then spread the experience to the whole country. A teacher at the scene suggested that I can do experiments nationwide first, and then sum up good methods. This and my research are two kinds of ideas, which can give me some inspiration. "

  In addition, we need to pay attention to how to select students who are really interested in scientific research, so that the young student project will not become the "hat" of undergraduates. According to Mu Rongping, a researcher at the Institute of Science and Technology Strategy Consulting of China Academy of Sciences, some talent funding projects have become "hats", which has nothing to do with the funding itself. The problem is that subsequent employers regard these funding as a precondition for talent admission or evaluation. Funding outstanding undergraduates to do scientific research may not be a prerequisite for sending graduate students, which may be helpful to the selection of talents for young students’ programs.

  Can undergraduates do scientific research well?

  In the evaluation team that Pan Yi participated in, the projects declared by 11 students were very difficult, "it is difficult to make a complete solution in a short time", but Pan Yi did not expect these students to publish several papers or patents two years later, or to push the research problems to a new height. In his view, the real value of the young student project lies in that students can receive the training of scientific research paradigm and be more firmly involved in scientific research in the future. Mu Rongping pointed out to China Newsweek that the establishment of this project by the Natural Science Foundation is also in line with the laws of scientific research. Students need to participate in basic research, attend more academic conferences, communicate with outstanding peers at close range, and improve their thinking ability in solving scientific problems.

  According to reports, on August 21st, the day before the evaluation of young students’ projects, NSFC invited Pan Jianwei, an academician of China Academy of Sciences, Luo Yi, executive director of the Department of Chemistry and Physics of Chinese University of Science and Technology, and other scientists to give academic reports to the undergraduates who participated in the evaluation. Dou Xiankang said, "In the future, we will provide them with more opportunities to participate in comprehensive high-end scientists’ forums, hoping to inspire and guide them to embark on the road of scientific research by letting top scholars at home and abroad communicate face to face with outstanding undergraduates, making reports, talking about experiences and feelings."

  Mu Rongping told China Newsweek that, according to the laws of scientific research, different disciplines are different, and many scientists at home and abroad have made outstanding achievements at a young age in basic theoretical disciplines such as mathematics and physics. At present, the young students’ program is still in the pilot stage, with a small number of students selected and a low amount of funding, which may not be as much as a large project of the Natural Science Foundation of China. It is a good attempt to select students who are really interested in scientific research, and the outside world can give more tolerance.

  Pan Xin has more than ten years of teaching experience, and is also responsible for the teaching reform planning and scientific research development of the college. In his view, the young student program is a "flag" and signal, that is, the state attaches importance to the coordinated development of education, science and technology, and talents, which can guide more university administrators to think about talent training at the undergraduate level.

  Pan Yi pointed out to China Newsweek that most of the courses at the undergraduate and postgraduate levels in domestic universities are imparting known knowledge. There are fixed class hours in one semester, and what to talk about in each class will be planned in advance, eventually teaching students a set of systematic knowledge. Only when students really enter a research topic can they begin to transition to exploring the unknown. He hopes that this process can be advanced.

  As early as 2005, the famous "Qian Xuesen’s question" was put forward. Today, how to cultivate top-notch innovative talents is still a common challenge for China University. Pan Yi noticed that some undergraduates, even postgraduates, lack scientific research training, and it is difficult to write a paper that people can understand. In his view, China’s basic education, undergraduate courses and practical equipment in some universities are not bad, but in the postgraduate stage, there will be a clear gap between China and top foreign universities. In top foreign universities, most natural science courses are required to write papers or reports at the end of the class. Students need to think, investigate and explore the unknown on the basis of the classroom knowledge system, but most courses in domestic universities still test the known content.

  Mu Rongping believes that what is more important behind the young students’ project is how colleges and universities can reverse the learning and thinking habits of undergraduates, and turn from memorizing answers to discovering and exploring problems. "The key to real scientific research is to see who can find the real problems".

  Lu Xiaodong, a researcher at Peking University Institute of Education, has been paying attention to undergraduate research for many years. In his view, NSFC’s funding for undergraduates is not new, but there is a new funding channel. Over the past 20 years, many universities in China have been supporting undergraduates who have the ability to learn to participate in scientific research. The traditional impression that "doctor is the entry stage of scientific research" is actually a cognitive misunderstanding.

  Take Peking University as an example. In 1998, Li Zhengdao set up a "political fund" to introduce the scientific research model of American research universities into China. Subsequently, Peking University established a set of management system with "research courses" as the core, and incorporated undergraduate scientific research into the regular curriculum. Relevant subsidies included "political fund", "president fund" and "Mao Yugang fund". According to the "research course" of Peking University, the applicants should be sophomores, and their GPA should rank in the top 30% of the college. At the same time, the standardized management of the course requires students to ensure that they invest enough time, and there are requirements for the mid-term and completion of the project.

  Pan Wei introduced that since 2021, Beihang University has conducted pilot research classes for sophomores and juniors. Each pilot college will open a research class as an elective course, accounting for 2 credits, and requires key laboratories at or above the provincial level to invest certain experimental conditions to support students. Pan Yi mentioned that compared with the traditional classroom, the scientific research classroom is open, and students may be faced with the most cutting-edge science and technology in a certain field. They can do experiments, research or theoretical formula derivation. There is no standard answer to this process. The most important thing for students is to learn scientific research paradigm, cultivate the ability of literature research, independently design operable experiments and write experimental reports.

  "We have been piloting for 3 years, and about 90% of the undergraduates of Beihang University have taken scientific research classes. I obviously feel that after the preliminary training, the level of graduation design has been significantly improved." Pan Yi told China Newsweek. Lu Xiaodong once met some undergraduates who quit halfway because of lack of interest when doing scientific research projects. There are also some students who have participated in short-term laboratory projects in different disciplines. Many teachers have found that these students are seriously involved in each project, and they gradually clarify the future research direction in the process, even if they do not produce visible research results, they are also very valuable.

  Compared with China, foreign top research universities began to encourage undergraduates to do research earlier. As early as 2000, Lu Xiaodong went to the United States to inspect the management of first-class universities, focusing on undergraduate education at the University of California, Berkeley. As a research university, Berkeley attaches great importance to undergraduate scientific research, and even regards it as an important part of undergraduate education. Since the 1990s, the university has set up special funds to support undergraduates to do scientific research. In 1997, it set up an undergraduate research office to organize and serve students’ research. Besides providing some information about project application, it will also help students understand what research is, how to write project applications and draw up reports through lectures. In addition, Harvard University, Massachusetts Institute of Technology, California Institute of Technology and many other American research universities have set up relevant institutions and projects to support undergraduates to do scientific research.

  The undergraduate stage is a critical period for the cultivation of academic aspirations. Lu Xiaodong noticed that many alumni of Peking University who have made their mark in academia or returned to school as teachers have participated in research courses at the undergraduate level if they look at their resumes. In 2023, Zhang Cheng, a professor at Fudan University School of Management, and others published an article "The Impact of Undergraduate Research Projects on Personal Research Career Development — — In a retrospective cohort study, the research career development of undergraduate students and graduates of Fudan University from 2000 to 2017 was investigated, and the final sample included 576 data. It is found that compared with students who have not participated in scientific research projects, the probability of undergraduates who have participated in related projects graduating from doctoral programs has increased by 14.1%, and the probability of choosing scientific research positions in formal jobs has also increased by 17.2%.

  The article points out that the important reason is that early scientific research training promotes students’ understanding of scientific research and cultivates students’ self-confidence in this field. Zhang Cheng and others believe that the key is not simply to let students take part in teachers’ topics or simply to pursue the publication of articles, but how teachers guide students to complete scientific research tasks, achieve goals and constantly build confidence in this process.

  Relevant research points out that domestic undergraduate research projects have been carried out for many years, but the overall start is late, the coverage is narrow, the implementation effect of different universities is uneven, and relevant policies still need to be improved. Lu Xiaodong observed that in the past years, some university administrators have also visited Peking University to investigate their experience. In his view, the most important thing is that school administrators and teachers should first change the concept that gradual learning at the undergraduate level and problem-centered learning triggered by undergraduate research do not conflict, but will promote each other. To support undergraduates in scientific research, colleges and universities should first straighten out this problem. Secondly, relevant experts believe that the integration of undergraduate scientific research into the formal curriculum will help reduce the conflict between students’ participation in scientific research and course learning.

  In addition, experts say that domestic universities need to invest more resources in undergraduate research. In China, except for some top universities, most of the undergraduate research work is assigned to the Academic Affairs Office. The relevant teachers lack enough energy and time to organize undergraduate research, and some teachers lack understanding of undergraduate research training, so it is difficult to undertake detailed guidance. At the University of California, Berkeley, in order to support teachers to participate in students’ scientific research, teachers will receive project assistance and a small grant of $ 300~600 to partially pay for students’ research-related expenses.

  How to motivate teachers to actively participate is very important. In Lu Xiaodong’s view, taking undergraduates to do research really requires teachers to invest more energy. Some colleges and universities can give priority to selecting some willing excellent teachers. Teachers should also think clearly about the value and significance of this matter. Undergraduate scientific research courses can play a real role in the process of cultivating top-notch innovative talents, but it is not achieved overnight.

Baidu’s end-to-end speech language model is broken, the dialogue is super realistic, the cost is reduced by 90% at the highest, and the response is extremely fast in one second.

Author | Cheng Qian

Edit | Desert Shadow

Voice interaction has been played with new tricks? !

Wisdom reported on April 2nd that on Monday, Baidu released the industry’s first end-to-end speech language model based on new Cross-Attention, which has been launched online for free.

Summarize the newly upgraded essays with several key words: voice interaction.Ultra-realistic, ultra-low delay and ultra-low cost.

Super-fidelity refers to the fact that Wen Xiaoyan, equipped with a large phonetic language model, can understand Chongqing, Guangxi, Henan, Guangdong, Shandong and so onCharacteristic dialect can also realize emotional dialogue.; Ultra-low latency means that the waiting time of users can be reduced from the common 3-5 seconds in the industry toAbout 1 second, almost the same as talking to real people; Ultra-low cost means that in the voice question-and-answer scenario of telephone voice channel, the call cost is about lower than the industry average.50%-90%。

Jia Lei, chief architect of Baidu Voice, revealed that the model can be deployed on L20 card, and under the condition of meeting the delay requirement of voice interaction,The concurrency of dual L20 cards can be more than several hundred.. At present, the training process of speech language model is convenient, which can be realized by optimizing hundreds of cards in one week based on Wenxin model, and the optimization work itself is not complicated.

Compared with the application of big model in voice interaction scene, what is the uniqueness of this big model of voice language? How to reduce the call cost to 90% at the highest? How to interpret the innovation behind it? Zhi Dongxi had an in-depth exchange with Jia Lei, chief architect of Baidu Voice, trying to find the answers to these questions.

First, the real-life dialogue experience, the upgraded version of the text Xiaoyan voice interaction is more silky

The development of large-scale model in voice interaction scene is evolving towards a more natural, low-delay and highly realistic voice interaction experience. And this more anthropomorphic interactive experience, we get a glimpse of the embryonic form in the newly upgraded Wen Xiaoyan, which is equipped with an end-to-end phonetic language model and has become an emotional companion and all-round assistant.

First of all, Wen Xiaoyan has integrated information query including weather query, calendar query, unit conversion, stock price and so on.38 vertical assistantsIt can be seen that the efficiency of voice interaction is much higher than that of text interaction in these special scenarios.

Secondly, Wen Xiaoyan is rightProblems of timeliness and non-timelinessCan cope with encyclopedic inquiry, timely question and answer content of current political knowledge, and Wen Xiaoyan can search in real time, and follow the instructions accurately to reduce hallucinations; Non-timeliness issues such as common sense questions and answers are not a problem.

Finally, it is also the biggest difference between voice interaction and text. Wen Xiaoyan can be carried out with users.Emotional and natural communication, and can respond to feedback quickly, and realize realistic and anthropomorphic interaction effect.

Not much to say, let’s take a look at the actual effect of Wen Xiaoyan.

A major difficulty in speech recognition is dialect recognition. The pronunciation characteristics of dialects are rich and varied. The same dialect may have different pronunciations in different regions, and even the same word may have different pronunciations in different contexts. This makes it difficult for speech recognition system to accurately capture and analyze all pronunciation variants, which increases the difficulty of recognition. At present, Wen Xiaoyan has been able to deal with the characteristic dialects in Chongqing, Guangxi, Henan, Guangdong and Shandong. He can not only understand them, but also reply with the corresponding dialects.

Another major feature of voice communication is the need for multiple rounds of interaction. For example, in the following example, Wen Xiaoyan not only gives a method to distinguish budgerigars from different dimensions of adulthood and childhood, but also gives correct feedback in time when users interrupt to ask new questions.

Even if the reply contains many elements such as distinguishing the budgerigar’s sex and distinguishing from a certain fixed feature, Wen Xiaoyan gives a concise answer, and at the end reminds the user that he can record while observing.

In addition, human-computer interaction is often interrupted in the middle, such as the user gets the core information he wants or is not satisfied with the current output content, etc. When the user interrupts the voice playback to input, the voice recognition system may be mistaken because of environmental noise, unclear pronunciation of the user or confusion with the previous voice content.

In the face of children’s repeated interruptions, Wen Xiaoyan can accurately identify their needs of "changing a story", and when children say "Mom has already told it", they don’t automatically choose to change the story, but give an emotional reply in time to create an atmosphere of natural dialogue.

Wen Xiaoyan, an emotional interactive form, also extends its application to companion scenes in assistant scenes such as knowledge quiz. When the user mentioned "I’m in a bad mood", Wen Xiaoyan’s voice was worried and so on, and guided the user to tell the reason why he was in a bad mood and further enlighten him.

Second, brand-new cross-related attention, to create a very low training cost advantage

Different from the language model, the core difference of the phonetic language model is that it can produce emotion.

Jia Lei said that the text model only produces words, while the phonetic language model can have emotions. The key is two special links in the architectural diagram of the phonetic language model.TN Rhythm and Emotion Control of Personality and StyleThis is prepared for speech synthesis, which allows the big model to have the emotion of adapting the content while generating the answer, which is also the key innovation of Baidu’s end-to-end speech model.

Specifically, there are four key innovations.

First of all, this is released by Baidu.The industry’s first cross-modal speech language model based on Cross-Attention; The second is the model.Combining Encoder with speech recognition, the calculation of KV is reduced to 1/10.; The third isEncoder is combined with speech synthesis, and the output content can be controlled emotionally.; Finally,Efficient full query attention EALLQA, so that the KV cache is reduced to a few tenths.

On this basis, the model realizesIntegration of text recognition and text synthesis.On the basis of systematic end-to-end communication, these coupled technologies enable the model to realize a natural, realistic and emotional interactive experience on the basis of quick question and answer and quick understanding.

Jia Lei explained that the acoustic model is also a phonetic model, but usually large language models are connected by words. Therefore, in the process of integrating speech recognition and large language model, researchers share the process of Encoder and speech recognition in large language model to achieve the purpose of reducing the hard delay of speech interaction, and innovatively introduce cross-modal modeling, switching from Self-Attention to Cross-Attention, thus completing the integration of speech recognition and large language model.

Baidu proposes to use Cross-Attention to solve the cross-modal problem of speech and language. In this process, due to the speed limitation of the existing Attention technology in Cross-Attention speech language modeling, Baidu developed the EALLQA technology suitable for Cross-Attention, adopting implicit RNN two-level position coding, training MHA in 128 space, and inferring MQA in 512 space shared by all layers of the model, so as to achieveMake full use of limited training resources and reduce reasoning cost..

In the basic training of the model, Baidu uses self-distillation post-train the end-to-end speech language model of Cross-Attention based on the pre-training model of Self-Attention mature Wenxin language.

In fact,In speech model, the pressure of KV cache and KV calculation is much greater than that of text model.. Jia Lei explained that the essential difference between speech recognition and text model is that the first token at the beginning of a sentence determines the delay of speech recognition. For the large text model, users can wait for 2-3 seconds to give an answer after entering a paragraph of text, while in the large speech language model, users are less tolerant of reply delay, and they hope to hear the answer within 0.5-1 second.

On this basis, the end-to-end speech language model realizes low-cost training and low-cost high-speed reasoning. In addition, the speech language model also needs quick response and emotional response, which is the scene where another key technology is exerted.Streaming word-for-word LLM-driven multi-emotional speech synthesis. Jia Lei said that many rounds of continuous communication with emotion can make people want to continue communication.

Based on the streaming word-for-word method, its speech synthesis is to see one word jumping one word at a time, and the large model can help the speech synthesis to output the text normalized output, prosodic pause output and emotional output it needs, making the speech synthesis process flow like when people speak, and its adaptive emotional coverage can reach 17 kinds according to the text output.

In addition, there is a big pain point in speech recognition, which is that it can’t judge the starting point and ending point of the user’s speech, butLarge model blessing can make it analyze whether the user’s words have ended based on semantics.The semantics are incomplete and we need to wait.

Jia Lei further explained that,The activation of voice scenes requires extremely interactive cost, extremely fast delivery speed, intelligent and emotional humanized question and answer.. Baidu integrates speech recognition with large model to solve the problems of pre-fetching, hesitation, content understanding and quick question and answer, and integrates text synthesis with large model to output prosodic emotion needed in speech summation, thus solving the problems of context understanding and emotion control in synthesis. This makes the application potential of voice scene greatly improved.

Third, directly attack the difficulty of voice interaction, and enlarge Baidu’s end-to-end voice language model.

The continuous optimization of large model has significantly improved the robustness, naturalness and speaker similarity of speech, butThere are still many pain points in the previous technical path.This is why Baidu focuses on the end-to-end speech language model.

Compared with the communication between people, the response speed of large language model is slow, and users need to wait for a while to get a reply. In addition, voice communication is often accompanied by multiple rounds of dialogue and interaction, and it is extremely difficult for models to complete colloquial multiple rounds of interaction. Compared with texts, users use more scenes of voice interaction, and the surge of interaction will lead to the increase in the application cost of large-scale models, and the difficulty of large-scale application popularization will also increase.

On the traditional voice interaction route, it will be limited by the accurate response between contextual memory, noisy occasions, hesitant questions and interruptions.

Therefore, this has become a core contradiction in the field of voice interaction.The convenience of voice interaction determines its potential for large-scale application, and these pain points are hindering its popularization.Jia Lei believes that,The chemical reaction between speech and text is the key to find a breakthrough in a specific field in the future..

The appearance of phonetic language model is qualitative change, and its innovative synthesis technology makes the model not need to see the whole text of a sentence, but can synthesize a word by seeing the text of a word. On this basis, Baidu has excavated a unique application scenario. He gave an example. For example, when asking about the weather, users can quickly interrupt the next question when they get the temperature range of the weather. Its advantage is that the use cost of the model is greatly reduced, while the text model needs powerful hardware to achieve such efficient application, but the speech language model can achieve efficient concurrency with low-cost hardware.

At the same time, from the perspective of the whole voice interaction field, the accuracy of the speech recognition part of the large model has been greatly improved. Jia Lei believes that it is more a competition of speed, cost and answer accuracy.Cost reduction is the key to large-scale use of multimodal voice interaction..

Jia Lei said: "Cost reduction is the inevitable way of technological progress." The extremely low cost of Baidu’s speech language model means the possibility of large-scale industrialization. The landing application of AI is the core of the development of the model industry in 2025, and this model is the key to solving the speech problem.

Baidu’s accumulation in the field of speech recognition has a long history.

In 2018, the Deep Peak 2 model released by Baidu Voice broke through the traditional model that has been used for more than ten years, greatly improving the recognition accuracy in various scenarios. At the beginning of 2019, Baidu voice technology team announced the world’s first streaming multi-level truncated attention model SMLTA in the field of online voice, with a relative accuracy rate of 15%. In 2021, Baidu released the streaming truncated conformer modeling technology based on historical information abstraction-SMLTA 2, which solved the problems faced when the Transformer model was applied to online speech recognition tasks.

These technological innovations have been applied in many fields such as automobiles, consumer electronics and mobile phones. This time, in order to promote the large-scale application of speech language model, at present,Baidu has launched its online Xiaoyan and opened it for free, and plans to launch it on the open platform in April, and then it will be connected to call centers, speakers and other business lines..

Jia Lei mentioned: "Science may have national boundaries, but it has no corporate boundaries." Subsequently, Baidu opened the end-to-end speech language model, just to promote the application of the big language model in the speech field, which is conducive to the development of the whole industry and ecology.

Conclusion: Baidu’s phonetic language model is unsheathed, opening a new chapter with low cost and high efficiency.

Convenient, efficient, natural and friendly voice interaction, which is widely used in multiple scenes, is very important in the digital age. However, from the current actual effect, voice interaction has greatly improved in recognition accuracy, and now the competition focus of the industry is on its recognition speed, cost and accuracy of answers.

In this context, the release of Baidu’s end-to-end speech language model further broke through the cost, and proposed a new technical path, which pushed the industry competition of voice interaction to a new height. At the same time, Baidu will launch it on an open platform, which will accelerate the application and popularization of large models in voice interaction scenarios.

Chen Sicheng: Hong Kong films grew up with me. "Tang Tan" contains feelings of Hong Kong films.


Special feature of 1905 film network "For our generation of creators, the impact of Hong Kong films, especially those in the golden age, is just like Shakespeare’s plays and Jin Yong’s literature, which are buried in our blood and cannot be separated."


The director’s memories of Hong Kong and Hong Kong movies are those hot summer days spent in the video hall, the eldest brother who was playing drunken boxing in the video, and even more, he opened up a "dream-like" place that he imagined infinitely.


After becoming a director, Chen Sicheng has integrated his deep feelings for Hong Kong films into his own creation. The former "Hong Kong film fan" has become a new inheritor of Hong Kong film culture. The "Tang Exploring the Universe" initiated by him not only left traces of classic Hong Kong films in many bridges, but also specially invited his childhood idols to join in.


In the latest program of "Celebrating the 25th Anniversary of Hong Kong’s Return to the Motherland Together", Chen Sicheng also shared his unchanging love and pride for Hong Kong movies from fans to film creators.

Self-proclaimed "shadowy" creator "Hong Kong movies grow with us"


In the 1980s and 1990s, Hong Kong films experienced a golden period of vigorous development, and numerous excellent films emerged one after another. As a generation who grew up with Hong Kong films, Chen Sicheng bluntly said that the influence of Hong Kong films on the filmmakers he belongs to is "innate", "deeply rooted in the blood" and "inseparable".


In his memory, all his childhood happiness comes from the small video hall on the street in his hometown of Shenyang. "At that time, we began to have more ways to get movie resources. During the summer vacation, my leisure and entertainment way was to rent videos and take five or six thick discs home."


Like all the fans who came into contact with these classic works in the golden age of Hong Kong movies, Chen Sicheng was "hungry" to learn about that "dream-like place" through one story after another.


Jackie Chan’s kung fu classic, a series of comedies, the director’s series and so on … … These works, which influenced the whole of Asia and even the whole world at that time, were a cultural baptism for young people who loved movies.


"Just like Shakespeare’s plays and Jin Yong’s literature, Hong Kong movies have a great influence on me in the field of film and television creation." Since then, Chen Sicheng has also become a "loyal Hong Kong movie fan".



The filmmakers of the two places communicate with each other. "Hong Kong movies are the pride of China people."


Counting Chen Sicheng’s works after the director’s transformation, it is not difficult to find out the deep feelings of this "shadowy" creator for Hong Kong movies, no matter from the plot or the film creation level.


For example, Tang Ren and Qin Feng, partners in the series, were inspired by Plan A to some extent. Tang Ren, who plays the role of Tang Ren, is not only a punch in the film, but also a comedy in the plot. This kind of character setting is influenced by the kung fu comedy film led by Jackie Chan.


Not only Chen Sicheng, but also many directors in Hollywood and overseas, you can also find the traces left by Hong Kong films in his works.


In order to satisfy his long-term wish as a movie fan, Chen Sicheng also "used" the identity of the director to seek a wave of benefits for himself: "My greatest advantage is that I can cooperate with my former idols and predecessors through the creative process."


In the first directorial debut, Chen Sicheng invited his favorite idol; Previously released, they also made surprise appearances in eggs, and Yuan Wah and Qin Pei also appeared in this series of works.


These dream linkages are the epitome of the active cooperation between Hong Kong and mainland filmmakers. Nowadays, more and more Hong Kong directors are beginning to try different types of films, and stories from the mainland are also touching more Hong Kong compatriots through movies.


On the 25th anniversary of Hong Kong’s return to the motherland, the film exchanges between the two places have become increasingly close. Hong Kong films also promote the diversified development of China films with their unique style.


Chen Sicheng bluntly said that it is difficult and unnecessary to distinguish between Hong Kong and the Mainland. Tsui Hark and other directors have made great breakthroughs in the creation of new mainstream films: "I think this is a particularly good form of learning from each other and learning from each other’s strengths."


In the future, Chen Sicheng hopes to have more opportunities to inherit the best qualities of Hong Kong films and Hong Kong filmmakers, as well as their imagination of genre films. "The return of Hong Kong is the return of all cultures, but also the return of movies. The pride of Hong Kong is the pride of all China people." Chen Sicheng said, "I hope that through our joint efforts, Hong Kong films will be created again and Chinese films will be even more brilliant."


2.0T+ wet dual clutch (DCT) is finally on fire!

As a top-class product for the future, it has not completely broken the current design idea, but evolved again on the basis of the existing design language. In terms of design, the overall design of MINI is classic, the whole front face looks dynamic, the headlights on both sides are sharp, and the internal light groups are patchwork, which makes it bright when lit. The sideways lines that rise sideways create a feeling of being ready to go, which looks very sporty. In addition, with the design of inch wheels, the sporty atmosphere is even stronger. At the same time, the reasonable proportion of luggage compartment cover and enclosure also gives the tail a lovely visual center of gravity, and the round taillight group of the new car is more eye-catching.

Coming to the interior of the whole vehicle, the design of the interior of MINI gives people the feeling of sports style. The steering wheel is made of leather and feels good. The leather package area of the center console is not small, and it feels soft. It is equipped with a 6.5-inch suspended large-size central control LCD screen, which has a clear display and a fashionable design. The front row is also equipped with a manual air conditioning control system to freely debug the most comfortable space atmosphere. At the same time, the new car also provides leather seats, which can bring certain comfort.

MINI has a length of 4008mm, a body width of 1727mm and a wheelbase of 2567mm, which is quite satisfactory. In the same class, the wheelbase of MINI ranks second. As a small car, its body size does not occupy much advantage in its class, and its internal seating space is only basically enough. After all, it is limited by the length and shape of the body. The five-door skylight of mini 2.0t Cooper’s obsessive version provides a wider view, which can create a better visual environment and good sensitivity for the rear passengers and increase the light entrance for the whole vehicle. In the same model with the same price, the trunk volume of MINI ranks third. The space is relatively regular, without obvious protrusions, and the overall loading capacity is good.

The MINI2.0T COOPER S obsessive five-door version uses a 2.0 engine with a maximum horsepower of 178 and a peak torque of 280, matching the wet dual clutch (DCT) gearbox. 2.0 The engine matched with the MINI is quite satisfactory in power performance, with weak low torque and can feel hysteresis. MINI’s official measured zero-acceleration score is 6.8S, ranking 4th among small car models with more than 800,000.

Wang Sicong came to the door for a private tutor, with a cold expression and simple clothes. The decoration power of the home was broken by rumors!

The truly wealthy people in the world are not those who aspire to a life of luxury. They are those who can do things that make them comfortable and content. And for those who have achieved financial freedom, their lifestyles may be confusing or puzzling to others.

Wang Sicong, a famous second-generation rich man in China, has recently caused heated discussions among netizens due to the ordinary and low-key nature of his daily life.

Recently, a fitness coach posted a photo on social media with Wang Sicong. In this photo, Wang Sicong is dressed in a red T-shirt and looks very ordinary. His indifferent expression contrasts sharply with the warm smile of the fitness coach.

In addition, Wang Sicong’s complexion looks very bad, with a dark face and heavy bags under his eyes, which makes people can’t help but worry about his health. Some netizens even believe that his gloomy face is caused by excessive nightlife and stress.

Although Wang Sicong’s daily life seems ordinary, his life is actually not ordinary. His home is luxuriously decorated, and although his clothes look ordinary, they are actually expensive. In addition, he also hires a personal fitness trainer, which is naturally expensive.

Therefore, although Wang Sicong’s daily life may seem ordinary, this does not mean that he is poor. On the contrary, his life is actually very rich. His lifestyle reflects that his wealth does not need to be displayed through a luxurious lifestyle, but through the satisfaction of his own needs and the pursuit of his own happiness.

So while Wang Sicong’s lifestyle may be confusing to some, that doesn’t negate his wealth status. He has chosen a lifestyle that suits him, and that’s the freedom and choice his wealth brings him.

Six departments interview + local government intensive warning, where is the future of online car-hailing?

  CCTV News(Reporter, Wang Jiazu) On November 11, six departments centralized "reminder interviews" with 8 online ride-hailing platform companies to remind and supervise the safety production, maintenance and stability of each enterprise. The reporter found that since the second half of this year, many traffic control departments across the country have issued risk warnings to online ride-hailing business services.

  Experts say that government departments’ interviews with online ride-hailing platforms and risk warnings can help guide enterprises to standardize their operations and focus competition on how to improve the safe travel experience of ordinary people, rather than seeking profit margins at the policy edge.

  Interview warning: online car-hailing is risky, so you need to be cautious when entering the market

  According to the news released by the Ministry of Transport on the centralized interview, since the second half of this year, there have been many new situations and new problems in the development of online car-hailing and ride-hailing markets, involving various aspects such as industry safety and stability, which have attracted extensive attention from all walks of life and the media. Based on this, before the interview, many transportation authorities across the country have issued business service risk warnings to enterprises and individuals engaged in online car-hailing.

  On June 11 this year, the Xi’an Taxi Administration Office reminded companies or individuals who are willing to engage in online car-hailing business to pay close attention to vehicle ownership to avoid conflicts and disputes or economic losses. In mid-October, the Xi’an Municipal Transportation Bureau also clearly stated that it is necessary to "prevent the online car-hailing market from being controlled by interest groups, break through the market boundary, over-dump vehicles, cause market competition to deteriorate, and ensure market supply and demand balance."

  Sanya City, Hainan Province, also issued a "warning" for online car-hailing on September 5, saying that some cooperative companies that join the online car-hailing platform have "rental purchase", affiliated operation, guarantee car purchase and other situations… It is very likely to cause unclear vehicle ownership, difficulties in rights protection in the process of canceling the contract, and joint and several liability in the event of business risks.

  In addition, Nanning, Sichuan, Suining, Mianyang, and Cangzhou, Hebei have also issued online car-hailing risk warnings this year, indicating that engaging in and riding online car-hailing pose certain risks.

  Case: "Purchasing by rent" makes drivers feel uneasy

  So, what are the risks of engaging in online car-hailing? The reporter found that in the risk warnings issued by these cities, the phenomenon of "rental purchasing" was highlighted. "Rental purchasing" means that the leasing company comes forward to buy the car with a loan from the bank and rents it to the driver. The driver repays the principal and interest to the bank for the leasing company. After the contract expires, the driver redeems the ownership of the vehicle from the leasing company. In fact, this model has great risks.

  In August this year, dozens of car owners were deceived by a trading company in Chengdu. According to local media reports in Chengdu, the dozens of drivers "bought" vehicles of different brands in the company to engage in online car-hailing services by "renting and purchasing". They paid a down payment and agreed on a monthly repayment amount. However, before the vehicle was transferred, the company boss suddenly lost contact and left the building empty.

  In July this year, a number of online car-hailing drivers in Changsha, Hunan reported that because their company had promised that the vehicle was "certified" and was a compliance car, more than 100 drivers signed contracts in the form of "rental purchase". But after more than half a year, due to illegal operation on the road without a license, many drivers were detained by the relevant departments and fined tens of thousands of yuan. They originally wanted to make real money, but they were brought into the scam.

  Master Zhang, who has been engaged in online car-hailing operations in Xi’an for two years, told reporters on the afternoon of November 12 that the phenomenon of "renting and purchasing" in the industry is very common. "This business is not as profitable as when the platform gave subsidies at the beginning. Xi’an’s requirements for online car-hailing are basically B-class cars, and few people who can afford it will work hard." Master Zhang said that many online car-hailing drivers are sports cars to earn money to pay off car loans. The owner is not himself, and the heart of running a car is not at ease.

  Expert: Don’t seek profit margins on the policy fringes

  Li Mingtao, dean of the China International E-commerce Center Research Institute, told CCTV that when online car-hailing first appeared, people regarded it as a representative of the "sharing economy". Through the matching of Internet platforms, idle vehicle resources can be optimized to meet the diverse travel needs of ordinary people. However, in actual operation, relying solely on the information matching of network platforms has indeed caused many safety hazards and bad cases involving safety.

  "The six departments’ recent interviews with online car-hailing companies are also mainly to prevent online car-hailing companies from relaxing the control of the entry threshold for online car-hailing and ride-hailing for their own business interests. At the same time, the local authorities’ strengthening of risk warnings for’purchasing by rent ‘is also based on a large number of complaints about this model, reminding drivers to prevent and control related risks and protect their own interests." Li Mingtao said that these measures are necessary to help guide enterprises to standardize their operations and focus the competition on how to improve the safe travel experience of ordinary people, rather than seeking interest space at the edge of the policy.

  In addition, in response to the characterization of "Hitch behavior must not be for profit" proposed by the six departments during the centralized interview, Li Mingtao believes that the future Hitch platform profit model will be gradually adjusted to collect member value-added service fees through information docking.
