Baidu’s AI-related patented technologies: Doing battle with COVID-19

By Victor Liang, Senior Vice President and General Counsel of the Baidu Group

The coronavirus (COVID-19) pandemic poses a serious threat to public health and presents a major economic challenge for countries across the globe.

Three of the foremost challenges confronting countries in this ongoing healthcare crisis are: First, how to screen people with symptoms in an effective and timely way to avoid cross-infection in crowded places; second, how to ensure patients get quick and appropriate treatment amid the rapid spread of the virus and in the face of limited medical resources. Coupled with this are issues regarding how to speed up the pace of medical research and how to best share high-quality, accurate information with the public. Third, how to solve labor shortages in the areas hardest hit by the virus and ensure that society continues to operate in relative safety, while stay at home orders are in place.

In responding to these challenges, Baidu has swiftly applied its expertise in artificial intelligence (AI), and associated technologies and products, to support frontline efforts to prevent and control the pandemic. Baidu’s ability to quickly respond to the present health crisis is enabled by its long-standing investment in cutting edge research and development. Baidu’s substantial AI patent portfolio is testimony to the quality and breadth of Baidu’s research and development effort. As reflected in the examples below, Baidu is proud to be able to use these patented AI technologies to help address the urgent needs of society in today’s battle with COVID-19.

Overcoming the screening challenge

Accurate and efficient screening is critical to safely reopening society. To aid screening, Baidu has developed and deployed an AI-based temperature measurement system that quickly and easily monitors people’s temperatures. The system was deployed swiftly in transportation hubs, such as railway stations and subway stations, and has become an effective anti-epidemic technology.

Baidu has been building its AI patent portfolio for techniques, such as its AI temperature measurement system, since 2016. The company now has more than 100 patent applications in this field. Baidu continues to innovate in this area by further developing and optimizing its AI temperature detection technology. For example, among other techniques, Baidu is developing new innovations for the infrared temperature measurement of people wearing masks.

Baidu’s AI infrared vision technology helps solve the problem of rapidly detecting the body temperatures of large numbers of people in densely populated areas with high volumes of traffic. Because the system involves no human contact, it can quickly screen crowds to improve detection efficiency and accuracy with minimal disruption to the public. Importantly, it does so while keeping people at a safe distance, thereby, reducing the risk of cross-contamination.

In March 2020, as the virus began moving around the globe, the demand for technology to tackle COVID-19 started to increase daily in many countries. Baidu’s successes in developing and deploying products to tackle the disease and its spread in China was immediately recognized and attracted significant international attention. Many of Baidu’s AI-based technologies are now being exported overseas, allowing the company to play an important role in combating the global pandemic. As a result, the company is adopting a more comprehensive international patenting strategy to facilitate the transfer of its products and technology to the global market.

Baidu has swiftly applied its expertise in AI and associated technologies and products, to support frontline efforts to prevent and control the pandemic.

Ensuring rapid access treatment

Baidu has been building its portfolio of patents relating to "AI + Medical" since 2018, and is continuing to focus on this area of innovation. In the fight against COVID-19, AI + Medical has played and continues to play an active role in the prevention and control of the virus around the world.

Since the outbreak, there has been a surge in public demand for online consultation. Hospitals in China have started using the company’s “Smart Consulting Assistant” to help doctors make rapid diagnoses and initiate treatment online. This increased efficiency for medical consultations significantly reduces the burdens that would otherwise be placed on medical resources.

Baidu also provides free API interfaces to online health consulting platforms, public disease prevention and control platforms, online hospitals, and more. These platforms provide a direct interface with members of the public, providing responses to their questions, general information about COVID-19, as well as consultations. Using the tool can result in exponential efficiency gains because it can service tens of thousands of users a day.

Baidu has also leveraged its technology in the CT imaging field, which plays an important role in the diagnosis of coronavirus-related pneumonia. Traditional manual inspection of CT images requires significant work from highly trained professionals. To support the increased CT screening required by the virus, using PaddlePaddle, the company’s open-source deep learning platform, Baidu has partnered with LinkingMed (a Beijing-based oncology data platform and medical data analysis company) to develop an open-source AI model for pneumonia CT image analysis, which has now been put into use in hospitals in China. The open-source platform is also being used to support COVID-19-related clinical research and clinical product research and development across the medical sector.

Given the severity of the ongoing global healthcare crisis, Baidu has fully utilized its advanced technical capabilities, expertise and resources in developing specialized platforms for its Overseas Anti-Epidemic Philanthropic Program, which launched recently. The program provides four major services: online medical consultation, psychological consultation, expert live streaming, and safeguarding tools for users overseas. So far, the program has provided online consulting services for more than 400,000 overseas users in more than 100 countries. “I’m grateful for the technology and platform provided by Baidu. Baidu has become a powerful promoter for providing communication with high-level experts in the fight against the novel coronavirus,” says Carlos Larrea, the Ambassador of Ecuador to China.

Baidu technology is also making important contributions to the search for a cure to COVID-19. The LinearDesign algorithm, developed by Baidu Research in collaboration with Oregon State University and University of Rochester in the USA, is being used by mRNA vaccine companies to accelerate and optimize the design of possible COVID-19 vaccines. Baidu also provides a webservice, LinearDesign Webserver, to provide easy and free access to the algorithm. The algorithm needs only 16 minutes to design a stable mRNA sequence that has substantially better stability compared to wildtype sequences or randomly generated designs.

As in the example above, Baidu is making its AI + Medical-related patented products and services available to public organizations, contributing to disease detection, auxiliary diagnosis and treatment, public epidemic prevention and control.

Managing labor shortages

In the drive to maintain some kind of normality in people’s lives, demand for autonomous services is surging. Baidu’s Apollo low-speed autonomous car is a typical example of such technology.

The company has made available its Apollo open-source autonomous driving platform – with complete low-speed driverless micro-car kits and autonomous driving cloud services, to companies that are on the frontline fighting the coronavirus. The Apollo platform helps partners quickly develop and distribute vehicles for disinfection function to support frontline workers.

These products and services are underpinned by Baidu’s portfolio of patented autonomous driving inventions, which involves multiple core patents in the field of autonomous logistics vehicle and cloud computing technology. Baidu is voluntarily sharing these patented technologies and services with many partners, such as Neolix, Idriverplus, Jinlong Bus, Qingdao Wuniu Technology, Zhongke Huiyan, and many more. In so doing, its aim is to provide non-human-contact, autonomous services, such as the disinfection of medical vehicles, meal delivery, and real-time monitoring of the coronavirus. These collaborations have allowed Baidu to further enhance its contribution to the fight against the spread of COVID-19.
