On February 14, the fourth China Artificial Intelligence Competition jointly sponsored by the National Internet Information Office, the Ministry of Industry and Information Technology, the Ministry of Public Security, the State Administration of Radio and Television and the Xiamen Municipal People's Government was officially launched in Xiamen. It is understood that the China Artificial Intelligence Competition is a unique national competition in the field of artificial intelligence. It has been successfully held for three times in Xiamen. So far, hundreds of excellent technical teams have been discovered, many important achievements have been released, a number of high-quality projects have been promoted, and good social reputation has been achieved. As the host city of the competition, Xiamen has attached great importance to the development of artificial intelligence industry in recent years. Through the construction of artificial intelligence industrial park, it has innovated the whole chain incubation mode of "incubator accelerator industrial park"; Build artificial intelligence supercomputing center and Kunpeng supercomputing center to fully guarantee the demand for computing power; The new generation of intelligent AI industry technology promotion center and AI security research institute were established; Focusing on a series of core basic fields such as intelligent sensors, machine learning, pattern recognition, etc., we have carried out a series of super-strong measures such as technical breakthroughs and unveiling and commanding actions, and made every effort to build a benchmark city of artificial intelligence. At present, Xiamen has gathered hundreds of enterprises in the industrial ecosystem, owning more than 10000 pieces of relevant software copyrights, and emerging a number of leading enterprises, creating a number of Xiamen brands in the fields of intelligent networked vehicles, intelligent unmanned aerial vehicles, smart home and so on.
