Shulou(Shulou.com)06/02 Report--

Of the 21 new confirmed cases of COVID-19 in Chinese mainland area on March 16, there was only one primary case in Wuhan, and the rest were imported cases from abroad. At this point, we should be sure that the epidemic in China has been basically brought under control and that an important shift has taken place in the main battlefield of epidemic prevention.

In the face of the epidemic, many forces and great heroes that can not be ignored have emerged, and AI technology can undoubtedly be among them. This is the first time in human history that AI has been used to help deal with large-scale public health events, and it turns out that China has succeeded and China's science and technology industry has completed its task.

On March 2, the Chinese Academy of Information and Communications, together with a number of science and technology enterprises, jointly released the Research report on the Application of data and Intelligence in epidemic Prevention and Control (version 1.0), which comprehensively demonstrated the application of big data and AI technology in the prevention and control of the epidemic.

The report points out that Chinese science and technology enterprises represented by Baidu have fully activated the potential of AI technology to fight the epidemic in the aspects of epidemic analysis and prevention, medical treatment, and resumption of work and production. The new generation of information and communication technology has become a powerful weapon in the war against "epidemic".

As pointed out in the report, Baidu has shown a representative backbone in this intelligent anti-epidemic tide, which has aroused widespread concern in the whole society. and it has been introduced to all parts of the world by the global science and technology media as the core part of "China's anti-epidemic experience".

Since Baidu Fireline announced the establishment of a 300 million yuan epidemic and public health security special fund on January 26th, in 50 days, a new generation of technology represented by Baidu AI has been stationed in various social scenes, industrial processes and scientific research bases related to the fight against epidemic.

In the first large-scale AI anti-epidemic, Baidu can be said to have completed a groundbreaking exploration and achieved a leap from scratch. When the dawn is about to rise, reviewing the 50-day anti-epidemic storm, we can summarize Baidu's intelligent anti-epidemic journey into a complete system, from which we can think about the next stage of global anti-epidemic, as well as the intelligent future of various industries.

To sum up, Baidu intelligent epidemic resistance shows several basic differential characteristics: the largest scale, the highest level of intelligence, the most prominent irreplaceability of the scene, and crossing the boundary between physics and the real world. These characteristics are integrated into three kinds of technology output forms to form a complete intelligent anti-epidemic matrix.

For Baidu, the highest score in this intelligent anti-epidemic test is the only answer.

Blitzkrieg: let AI point to the key to the fight against the epidemic

The core reason for the importance of intelligent anti-epidemic lies in the blessing of AI technology, which makes it possible to accomplish many tasks that cannot be accomplished under the original technical conditions, and plays an irreplaceable role in the whole anti-epidemic system.

This layer of value can be called intelligent anti-epidemic blitzkrieg. After the outbreak, Baidu quickly decided to send a long-accumulated basic AI algorithm to send "flash attacks" to key areas deep in the epidemic.

For example, on January 30, just after the outbreak began, Baidu announced that it would open the linear time algorithm LinearFold free of charge to genetic testing institutions, epidemic prevention centers and scientific research centers around the world, in order to improve the prediction speed of novel coronavirus's spatial structure, thus helping to prevent and control the epidemic.

The value of the LinearFold algorithm is that it can shorten novel coronavirus's genome-wide secondary structure prediction from 55 minutes to 27 seconds, which is 120 times faster, and greatly improves the efficiency of epidemic detection and vaccine development. Behind this algorithm, Baidu started RNA secondary structure analysis in 2018, hoping to use AI to accelerate RNA-based vaccine development, drug development, virus analysis and so on. In July 2019, Baidu first published the LinearFold algorithm, which makes it possible to predict the RNA structure of the whole sequence and genome.

Baidu's accumulation and exploration of LinearFold algorithms directly formed a sharp weapon of AI during the epidemic. At present, LinearFold algorithm has provided help to more than 100 novel coronavirus scientific research institutions all over the world, and has become an important firepower for human beings to contribute to the core of COVID-19.

The use of AI algorithm ability directly brings about changes in the anti-epidemic battlefield, which is also reflected in the fact that Baidu is the first in the industry to open source mask face detection model. On February 13, Baidu announced the free and open source face detection and classification model of the first mask in the industry, so as to effectively detect all faces with and without masks in dense flow areas, and at the same time judge whether the person is wearing a mask or not. the accuracy of mask discrimination reached 96.5%, which directly improved the epidemic prevention efficiency of public places during the critical anti-epidemic period, and ensured the efficient operation of resumption of work and railway shipping traffic.

(it took only 3 days for Baidu engineers to help Beijing Metro launch the AI mask testing program.)

With the integration of Baidu AI technology, the efficiency of some key areas of anti-epidemic may be greatly improved. This direct indicator points to the importance of AI technology.

Encirclement: Baidu brain's epidemic defense in thousands of industries

Baidu's intelligent anti-epidemic project, on the whole, is to deepen and integrate the new generation of information technology represented by AI, big data and cloud computing into various industries and scenes, thus carrying out large-scale actual combat with intelligent technology in social multi-scene coordination.

Rather than mass immunization, we prefer large-scale AI to surround the epidemic and let intelligent technology become the immune layer of human society.

Since the launch of the "War Plague" defense plan for Baidu brain AI developers, Baidu brain has used an average of 220 million AI technology per day. AI technology exported by Baidu brain has entered thousands of industries, realizing the common completion of "encircling the epidemic with AI" by the whole society. To cite a few examples, Luoyang Leqiang Technology used Baidu voice technology to develop a "Smart Translation Video subtitle system (Baidu Anti-epidemic Special Edition)", which converts online course videos into subtitles in real time to ensure that hearing impaired students can also successfully complete their studies during the epidemic. At present, the system has been established in Tianjin University of Technology, Beijing Union University, Changchun University, Zhengzhou Institute of Engineering and Technology, Zhengzhou normal University, Xi'an Academy of Fine Arts, Chongqing normal University and other universities and special schools, covering more than 30 special school teachers and accumulating more than 20,000 users.

With the help of free computing resources provided by Baidu brain, voice recognition technology interface and special directional service and docking access, Dalian Houren optimizes the poetry pairs learning function module of "Export Chengzhang" APP "Fei Hua Ling", realizing that the recognition rate of poetry pairs to students reciting poems is more than 99%, ensuring the smooth and stable online learning of more than 1.8 million primary and secondary school students. The Beijing Zijie team and Baidu brain Voice Technology team optimized and developed a "clinical nursing data acquisition system" for COVID-19 medical symbol units, allowing front-line medical staff to use intelligent voice technology to input dozens of items of nursing information in 10 seconds. the recognition accuracy is more than 92%, which greatly improves the efficiency of front-line work.

Hangzhou McSugar uses Baidu OCR technology to develop an intelligent epidemic prevention system for front-line traffic police. Using Baidu brain OCR ID card intelligent recognition technology, only 18 hours to develop the online "document management epidemic version" customized APP, can help the traffic police team to quickly collect vehicle information, achieve real-time management of personnel flow, has been installed by more than 500 front-line traffic police, and officially used in a number of traffic police departments and their subordinate departments.

(people in and out of communities in Jufeng Town, Lanshan District, Rizhao City do not need to register by hand to avoid contact with infection and achieve scientific prevention and control.)

There are many cases like this. Using the AI technology output by Baidu's brain, technology companies and developer teams from all over the country took action during the epidemic, sinking to the real front line of anti-epidemic and social life scenes, using AI technology to solve a variety of long-tail pain points, so that individual needs have been targeted.

Encircling the epidemic with AI is no longer hypothetical in the past 50 days, but a beautiful picture that actually appeared on the land of China. Among them, Baidu brain, as a hardware and software integrated industrial production platform, makes this "encirclement war" a prerequisite for the realization of this "encirclement war".

Positional Warfare: Baidu Product system and Intelligent epidemic Prevention

With Baidu AI ecological composition of the long tail around, Baidu's own product system in the anti-epidemic period of the "intelligent battle", formed several key positions of the key attack. With the integration of Baidu intelligent technology and product layout, a number of Baidu industrial systems were given new identities during the epidemic, while the differentiation brought about by AI technology also made Baidu products perform amazingly in the industry in the first quarter.

In retrospect after the end of the epidemic, we should find that great changes have taken place in the audience's evaluation and positioning of Baidu products, whether in the B-end or C-end market. Perhaps these changes can be turned into medals after the intelligent war against the epidemic.

Let's give you a few examples:

1. Baidu map as the time and space pointer of a special period.

Since the beginning of the epidemic, Baidu Map has quickly launched a number of real-time functions related to the epidemic. For example, Baidu Map epidemic area function, covering tens of thousands of epidemic sites in 261 cities, with a cumulative number of queries of nearly 100 million as of February 24; another example is Baidu Map Migration platform and National Real-time Road condition platform. It has become a key data platform for the public and government departments to judge the traffic situation during the period of returning to work. By March 15, it has provided more than 2.24 billion services. Baidu Map exclusive combined with Health China online fever clinic map, covering a total of 361 cities across the country tens of thousands of fever clinics, for patients in the special period of the first time to seek medical treatment, reasonable planning of medical strategies to improve the important support.

During the epidemic period, Baidu Map's effective use and development of spatio-temporal data made us see many new functions of artificial intelligence maps, which subverted users' common sense judgment of map products to some extent. The new expectation will continue until the end of the epidemic and become the key to the success of the mobile map industry in the AI era in the future.

2. Baidu smart cloud with software and hardware going to the anti-epidemic battlefield in a comprehensive way.

In the complex social scene that requires the integration of software and hardware and a high degree of integration of the original edge, Baidu intelligent cloud has become the firepower point for Baidu to output intelligent anti-epidemic capability. For example, Baidu Intelligent Cloud took the lead in deploying the AI temperature measurement system at Qinghe Railway Station in Beijing, which can detect the body temperature of more than 200 people in one minute under the sequential passage of a single person, greatly improving the passing efficiency of the testing population and relieving the detection pressure on the transportation hub. At present, this system has completed the deployment of dozens of temperature measurement sites across the country, covering transportation hubs, administrative agencies, medical institutions, corporate offices, residential communities and many other scenes. By the end of February, Baidu AI temperature measurement system has completed rapid temperature tests of more than 7 million people nationwide.

In addition, Baidu Smart Cloud also opened a free intelligent outbound call platform during the epidemic, which can use AI voice technology to realize outbound call service in three scenarios: mobile personnel screening, local residents' return visits, and notification of specific groups of people, which is hundreds of times more efficient than manual phones. The platform has been put into use in more than a dozen areas such as Beijing, Shanghai and Yan'an, Shaanxi Province. as of March 1, the total number of external calls has exceeded 3 million.

From cloud computing to smart cloud, the intelligent technology in the anti-epidemic battlefield makes people from all walks of life see the new value of cloud services, and the rapid deployment and technical capability differentiation of Baidu intelligent cloud has also become a new bright spot in the cloud service market.

3. Baidu Apollo, which helps to realize unmanned anti-epidemic.

The scene unmanned service capability provided by autopilot technology itself is very critical in the anti-epidemic battlefield, and can become a key force to effectively avoid cross-infection and complete transportation operations. On this anti-epidemic battlefield, the new army composed of unmanned equipment has become a landscape. Baidu Apollo has joined forces with partners such as Neolithic, Smart Walker, Apolong, White Rhino Xiu, Qingdao Wuniu Technology, Songling Robot, Botian and other partners to quickly achieve the goal of putting unmanned equipment into the anti-epidemic battlefield. At present, there are more than 100 unmanned vehicles equipped with Apollo system to carry out disinfection operations, logistics, transportation, material distribution and other important tasks in the anti-epidemic front line, covering 17 cities, including Wuhan, Beijing, Shanghai, Shenzhen, Guangzhou and so on.

From spatio-temporal data, software and hardware solutions for cloud computing output, to unmanned devices, these key capabilities play an important role in the anti-epidemic battlefield, and also show the industry the effect of intelligent upgrade brought about by AI. From another point of view, the intelligent capability output schemes in multiple anti-epidemic battlefields finally form the overall system of Baidu intelligent anti-epidemic. When the global epidemic begins to spread, perhaps Baidu's intelligent anti-epidemic will be an important "Chinese experience" for exporting to the world.

Conclusion: Baidu Intelligent War Plague and Chinese experience

For the overall global anti-epidemic situation, there are a variety of policies, and the medical system has its own characteristics, but science and technology is stateless. The intelligence of the whole industry, the improvement of efficiency in the core scientific research areas and the deployment of intelligent solutions in key scenarios brought about by AI can build a new Great Wall of science and technology anti-epidemic in the community with a shared future for mankind.

On March 12, the MIT Science and Technology Review published a report entitled "how Baidu uses artificial Intelligence to fight the epidemic", which shows the results of the application of Baidu AI technology in virus analysis, real-time screening, auxiliary diagnosis and treatment, big data analysis and so on. The article reminds governments around the world that they should increasingly seek the help of AI technology to combat the epidemic with digital technology.

It can be said that Baidu's intelligent anti-epidemic model and experience has begun to spread to the world, and will continue to play a unique value. The temperature of science and technology and the responsibility of AI are all reflected in the speed, efficiency and promotion of this intelligent war against epidemic.

Baidu CTO Wang Haifeng believes that Baidu has been giving full play to its advantages in AI, big data, search, and information services, helping front-line epidemic prevention and control work, or helping frontline anti-epidemic workers to improve efficiency and ensure safety, or providing scientific data reference for the government and research institutions, or providing timely and effective services for the general public. This is our practice of the mission of "using science and technology to make the complex world easier", and it is also our responsibility and responsibility.

The chain achievements of intelligent anti-epidemic will continue to show. in these 50 days of experience, Baidu has not only completed a task, but also carried out actual combat in the real world "ahead of time" of intelligent technology that can be used for a long time in the future. the precipitated technical capability and solving experience are the precious wealth of China's industrial intelligence and social intelligence in the future, and will also play a more unique technical value in the global anti-epidemic process.

This is a "Chinese experience" that will eventually be written into history.
