2020 Spring Festival, destined to be carved into everyone's memory. The face of the sudden outbreak of pneumonia novel coronavirus infection, in addition to front-line health care workers worked day and night, "artificial intelligence" is also a special period to the forefront of the fight against SARS to accept baptism.
March 13, the first phase of the Open Day for the first time this year, Baidu brain in the form of live launch "AI Contagion" special. Baidu AI technology ecosystem, senior product manager for both the comprehensive analysis of AI technology Baidu brain during the launch of the epidemic, including more than 10 to wear special masks Face Detection fight against SARS and AI temperature program, OCR information collection and medical research, online education AI technical capabilities, to show the effect of the application of artificial intelligence techniques in the field of battle the epidemic.
Wear a mask face detection algorithm based on model PyramidBox
In the live broadcast, both in details the masks face detection and classification of external open source model Baidu announced the industry's first fly by paddle PaddleHub, Baidu open platform further brain will wear masks Face masks detection and AI-related capabilities are all open and offers a variety of product forms public cloud API, offline SDK, privatization deployment package and so on.
According to reports, the model can effectively detect the flow of people-intensive area of all faces, and determine whether they wear a mask. Meanwhile EasyDL on the line masks detect pre-training model, customized training support online.
This program, for face recognition model based on research and development in 2018, Baidu top international Conference on Computer Vision ECCV papers PyramidBox 2018, the training of research based on self-depth fly paddle open-source learning platform, and so on through a paddle-slim model miniaturization technology such algorithm can run efficiently on a limited number of operator force device.

On the introductory page on EasyDL special masks detection algorithm, Baidu marked with special masks detection algorithm suitable for people wearing face masks to detect whether the use at the scene, and there are certain requirements for data, such as requiring data tags for mask and unmask, which represents a mask to wear a mask, unmask represents not wearing masks.
Currently, this service has to wear a mask in public areas enabling detection of brush wear masks and other face traffic scenarios, more than 90% recognition rate, sideways, can effectively identify when turned around, can be used to identify whether or not to wear during the epidemic passers masks, remind, guide and so on. Baidu said that such a high accuracy is the result of a large amount of training data, the new model uses a training data over one hundred thousand pictures, to ensure adequate and effective sample size.
AI temperature measurement system consists champion Face Detection & Tracking WiderFace support
In fact, Baidu brain epidemic prevention and control management of the special screening of AI technology is already used in many areas of epidemic prevention and control, in order to combat "plague" inject scientific and technological strength.
Baidu AI temperature measurement system deployed in Beijing 19 temperature monitoring points Qinghe railway station, there are more than a million people passed the test. By using this system, the high population density, high flow environments, may be implemented at the subway station River pass sequentially over the single channel 200 within one minute while the temperature is detected in real time. Intelligent outbound platform at the Beijing Haidian has also been on the street, Xi'an, Yan'an, Shanghai Baoshan, Ruian City, Wenzhou, Zhejiang, more than a dozen areas in use, outbound total more than 300 million times.
This program uses AI AI temperature and infrared thermal imaging face recognition technology integration, the use of a champion face detection & tracking algorithm WiderFace, for precise positioning of the face, leading model-based Paddleslim miniaturization technology, can achieve 10 times more destructive model training accelerated. Further, professional infrared sensors, temperature makes the temperature difference is only 0.05 degrees, a very high sensitivity.
In addition, Baidu brain AI technology will also be applied in the field of medical research, such as a diagnostic aid, information collection and other front-line health care cases, in order to ease the strain on the resources of medical fight against SARS, first-line health care workers overworked. For example, both talked about, even the heart of the medical line paddle on Baidu flying platform "pneumonia screening and disease based on CT images of the pre-assessment AI System" has been the first ground-based Affiliated Hospital of Hunan Chenzhou, Hunan University, and lesion detection on the test data set precision and recall can reach 92% and 97%, respectively, so that to prevent undetected in ensuring high precision on the basis of lesion detection.
Both OCR also presented a case study of how energized community prevention and efficient information collection. For example, Shandong Extension Information technology companies in support of Baidu brain OCR recognition technology for the smart ID card Arashiyama District, Rizhao City CDC promptly launched a "follow-up disease control home health management platform" and "pneumonia prevention and control of access control platform" two set of systems, real-time monitoring of the health of community residents, has been used in more than 80 local governments, enterprises, covering more than 1.8 million people.
For to "keep closed school" in the teacher-student school, the Baidu also provides a boost brain areas related to speech technology to educational institutions, such as a real-time voice technology enterprises to use Baidu launched the "wisdom translated hearing impaired video subtitling system" for the hearing-impaired students access to the Internet during the epidemic class.
AI developers Contagion guard program
February 6, Baidu released the AI based on Baidu open platform and fly brain paddle depth learning platform "AI developers Contagion guard program."
During the broadcast, both specifically describes the specific content and progress "AI developers Contagion guardian Plan": including OCR text recognition, voice call center capabilities, news summaries, intelligent and customized dialogue and epidemic prevention and other services platform UNIT strong AI application-related explain technical capacity; providing free resources, special service areas and in-depth technical support to help developers and businesses to reduce development costs, to support the development and application of epidemic prevention and control products.
Fly paddle depth learning platform provides a synchronization code upgrades highest priority emergency support, free calculate force support, targeted support specialists, support enterprises and developers deep learning AI epidemic prevention technology development related products, projects and academic research applications, and promote the fight against SARS epidemic prevention product development , drug discovery, disease prediction, clinical trials and other work faster and achieve results.
In addition to the technical capacity and support services provided by the two platforms, the plan for the majority of developers provides three major series, more than 100 church AI free online courses covering voice, vision, depth learning core AI technology, to encourage and support the development of who "cloud learning" unlock AI capabilities.
Baidu also launched a new market AI epidemic prevention topics, dozens of hardware and software products to meet the demand for more landing scenario the fight against SARS, such as science and technology through the door of an inner reaches epidemic prevention robots have Baidu's cabin off the local hospital, Guangzhou has launched the flying cloud epidemic prevention disinfection, no one delivery, security patrol three functions of disinfection and epidemic prevention intelligent robot "Xiaoyun."
In addition, Baidu through AI technology also done a lot. Time and space-based data flow analysis and trend forecasting staff affected areas, identifying key cities and regions; Baidu map on line and epidemic prevention function for all to see at any time the epidemic area, and search for the nearest fever clinics to be the first time aid; Baidu Apollo also announced the outbreak of service businesses free and open low-speed mini car kits and autopilot cloud services.
In the face of the epidemic, time is life, efficiency and speed is wealth, if AI continued to maintain the ability to landing scenario epidemic prevention and control of various, that the whole community can gain the upper hand in advance to control the epidemic. After landing AI will not just stop at the epidemic, the epidemic in the past, from industry to consumers, trust in the value of AI technology will be higher, which will accelerate the popularity of AI and landing speed.
