CT + AI, speed up the identification of infected people

In the field of medical care, with the increase of the number of patients infected and the expansion of the scope of the epidemic, the number of patients waiting in line for chest CT examination every day in the hospital is increasing rapidly. The overloaded operation of the imaging department in the hospital, the long waiting time of patients, and the high risk of cross infection are all the practical difficulties currently faced.

In order to alleviate this situation, surging news learned that conjecture technology has recently launched a special version of pneumonia AI developed for new coronavirus pneumonia, which has been put into clinical application in Tongji Hospital Affiliated to Tongji Medical College of Huazhong University of science and technology, a designated institution of Wuhan new coronavirus fever clinic. Conjecture technology is a service provider of artificial intelligence medical imaging diagnosis system, whose main product is the AI research and development design of early lung cancer screening, diagnosis and prognosis.

Limited to the production capacity and application environment of the new coronavirus nucleic acid detection kit, many basic hospitals are unable to quickly diagnose the infected persons by this way. According to the introduction of hypothetical technology, this system, through the way of CT + AI, can help speed up the identification of infected persons in primary medical institutions, and strive for time for rapid isolation, diagnosis and treatment.

In addition, there is a long incubation period for new coronavirus infection. With the progress of the epidemic, there have been cases of virus carriers with or without obvious symptoms infecting their families. All of these challenges the prevention and control of the epidemic. According to speculation technology, CT + AI system can be used to quickly and directly identify asymptomatic patients and early patients, which is an effective guarantee to fundamentally eliminate the epidemic situation.

Using AI model to speed up the search for human-to-human variation points of virus

The advantages of artificial intelligence in computing power have been brought into full play in the face of this epidemic.

According to the surging news, Shenlan Academy of Sciences of Shanghai Shenlan technology company has completed the establishment of cellular automata model based on the genome of the whole sequence of the new coronavirus, carried out 256 kinds of regular transformation statistics, and analyzed the human-to-human variation sites of S protein and N protein sequences of the new coronavirus and the corresponding protein sequences of the original SARS.

At the same time, this AI algorithm reduces the time of comparing the full sequence of virus genes to 3 minutes. The time of protein sequence comparison is reduced to second level, for example, the S protein comparison of SARS and new coronavirus (2019 ncov) only takes 3 seconds. The results showed that the similarity of amino acid sequence of S protein was 71.88%, and the longest sequence of S protein was located at 926 and 944, respectively.

The significance of the research results lies in that geneticists and virologists can carry out extensive gene comparison based on this, so as to determine the genealogical relationship and evolutionary path of the virus, and provide basis for subsequent vaccine and drug research and development. At present, Shenlan science and technology has decided to open this function to the society. Any scientific worker can quickly obtain the comparison results and the functional comparison of the family tree diagram and the virus sequence by applying and providing the virus gene sequence or sequence fragment.

AI helps to quickly screen people with abnormal temperature in public places

With the rework day approaching after the Spring Festival, public places in major cities across the country have become the key to epidemic prevention and control. How to achieve non-contact induction, efficient passage and high temperature intelligent early warning in densely populated areas has become a challenge for urban managers.

Surging news learned that on February 4, the team of Kuang Shi Technology (hereinafter referred to as Kuang Shi), a Chinese artificial intelligence enterprise, launched a solution system of human body recognition + human image recognition + infrared / visible light dual sensing.

This scheme can identify the high-temperature personnel in the flow of people through the front-end infrared camera, and then according to the human body and face information of the suspected fevers, through AI technology, it can assist the staff in all kinds of public places (train station, bus station, subway station, airport) and other high-density personnel flow scenes to quickly screen the people with abnormal temperature, so as to realize the non-contact intensive flow of people AI assisted temperature sensing solution The scheme can solve the traffic efficiency and controllability in the open place after the epidemic situation is stable.

According to Kuang Shi, compared with the artificial short-range detection method and the traditional fever screening system, Kuang Shi will focus on the research and development of remote temperature measurement accuracy and the availability of high-density human flow.

First of all, Kuang Shi carried out a special model optimization for masks. Even when masks and hats cover a large area of the face, the system can help the staff quickly screen the passing crowd, with the recognition error of u00b1 0.3 u2103. The public does not need to take off the protection or queue to gather, greatly improving the safety and detection efficiency of the public space.

Another major feature of the system is that it can support the non-contact remote temperature measurement of more than 3 meters. Once there is a suspected heating personnel, it will automatically alarm. Combined with the human Reid detection and retrieval technology developed by Kuangshi, the system can help the staff to quickly screen the location clues of fever personnel, so as to further confirm the detection and medical observation.

Classroom in the air

Affected by the epidemic, the spring semester of 2020 is generally delayed in all parts of the country. How to help students to study at home effectively, improve and build knowledge map? IFLYTEK has built an air classroom with intelligent technology.

According to iFLYTEK, with the Internet as the medium, online classroom can be built to realize remote teaching, teachers and students can have real-time classroom interaction and restore the classroom situation. At the same time, teachers can supervise and manage the classroom by setting students operation authority, real-time Click to, desktop lock and other functions; parents can also learn about students learning in real time through app; all teaching contents can be recorded for students to learn independently after class. At present, iFLYTEK provides smart air classroom (online live teaching system) for Hubei Province and other regions. The teaching program has been connected to 31 regions of 19 provinces in China, including Hubei, Anhui, Beijing, Shanghai and Tianjin, covering more than 8 million students. On February 2, iFLYTEKs free public welfare course for smart learning online school was officially launched, and the spring synchronous live broadcast course was free for junior and senior high schools. It is reported that the online spring synchronous live broadcast course of intelligent learning online school started on February 10 and lasted until the beginning of the school according to the development of the epidemic situation. From the first year of junior high school to the second year of senior high school, synchronous classes cover Chinese, mathematics, English, physics, chemistry and other subjects, and provide students with a variety of teaching models and real-world classroom teaching experience.
