Some research achievements have been applied and transformed, such as the intelligent service trading platform of ZBJ.com, which has built a portrait system of "employer-order-service category-service provider" and an intelligent matching method for supply and demand of "search-recommendation-assignment" services; the pharmaceutical intelligence network of Kangzhou Big Data, especially the COVID-19 big data platform assisting epidemic prevention; the social network analysis system for job-related crimes of Neusoft Group, etc., achieving significant economic and social benefits.
In recent years, this research has undertaken more than 10 projects, including the National Key R&D Program of China and the National Natural Science Foundation of China. Related achievements have been published in top international journals and conferences such as IEEE T. TKDE, IEEE T. NNLS, IEEE T. SC, IEEE T. Cybernetics, IEEE T. II, IEEE T. SMC Systems, AAAI, IJCAI, ICDM, etc. The research achievements have won important awards such as the First Prize of Chongqing Natural Science Award, the First Prize of Chongqing Science and Technology Progress Award, and the First Prize of China AI Technology Progress Award, and have cultivated many outstanding young talents.
（2）Research and Application of Large-Scale Adaptive Intelligent Visual Analysis Technology
Breakthroughs have been made in technologies such as "3D structured light and active near-infrared multimodal biometric live detection." The integrated biometric identification technology is at the leading domestic level, with a false acceptance rate reduced to one in ten million, meeting the stringent requirements for identity authentication. The achievements have been widely applied in civil aviation airports, finance, security, and other fields. Among them, 70 domestic civil aviation airports, 618 security inspection channels, covering 50% of the national security inspection channels, and 60% of airports with passenger flow exceeding 10 million people; in the field of smart finance, face verification services cover more than 70 commercial banking institutions at all levels, covering more than 160,000 bank branches, with a market share of ≥ 83.2% for banks with self-built systems, over 300,000 intelligent business terminals, and daily usage exceeding 300 million times. The research achievements have promoted the intelligent transformation of China's civil aviation security and financial sectors.
In recent years, this research has undertaken more than 10 major projects, including the National Key R&D Program, the "Internet+" Major Project of the National Development and Reform Commission, the AI Innovation Development Project of the National Development and Reform Commission, the National Natural Science Foundation of China, various science and technology programs in Chongqing, and the Special Project for the Transfer of Scientific and Technological Achievements of the Chinese Academy of Sciences. Related achievements have been published in top journals such as IEEE T. PAMI. The research achievements have won awards such as the Science and Technology Promotion Award of the Chinese Academy of Sciences, the First Prize of Chongqing Science and Technology Progress Award, and the First Prize of China AI Technology Progress Award; incubated CloudWalk Technology Co., Ltd. to list on the Science and Technology Innovation Board; and received multiple instructions from national leaders.
（3）Development and Application of Big Data-Driven Automatic Monitoring System for Aquatic Ecological Environment
Breakthroughs have been made in key factor detection technology for aquatic ecological environment, big data-driven aquatic ecological environment analysis technology integrating domain knowledge, and the construction technology of the aquatic ecological environment monitoring and early warning cloud platform. Automatic monitoring devices and systems for aquatic ecological environment have been developed. The "fine-grained numerical weather forecasting system" has been developed, establishing for the first time a meteorological radar and observation data assimilation model for complex mountainous terrains such as the Three Gorges, improving the accuracy of weather forecasting. The flood inundation deduction analysis system has been developed, realizing disaster warning and forecasting. This has promoted the integration and innovation of the entire technical chain for river basin water safety research and application, effectively enhancing the supervision and emergency response capabilities of the aquatic ecological environment.
