On the evening of February 16, Qi Guangpu won the championship in the men's air skills final of freestyle skiing in the Beijing Winter Olympic Games, which was the seventh gold medal won by the Chinese team at the current Winter Olympic Games. Behind the brilliant achievements, AI coach "Guanjun" quickly attracted the attention of netizens. "Guanjun" is not human, but the artificial intelligence referee and coach system developed by Xiaobing company, which is endowed with the characteristics of virtual human (AI being) such as appearance, voice and character. Qi Guangpu, Xu Mengtao and other athletes are inseparable from his help in preparing for the Olympic Games. Xu Yuanchun, chief operating officer of Xiaobing company, said that the "Guanjun" system has three core modules: the first is the basic module, which can accurately score the athletes' performance every time according to the standards of the International Snow Federation, and point out the deduction items; The second module is based on the international scoring standards to put forward specific opinions on the air movement trajectory of athletes, so as to help athletes form muscle memory; The third module is to track the longitudinal time dimension of each athlete's long-term training data, so as to help them gradually modify their training actions, so as to improve their competitive ability. "With an AI system like Guanjun, athletes can score immediately after jumping and tell them where they are doing well or not. In this way, it is not a process operated by people behind their backs, it is a fully automatic process. In other words, Guanjun has a unique ability to run itself." Xu Yuanchun said. Nowadays, many sports use "Ai coach" to help athletes scientifically improve their performance, and many companies are developing AI training assistance systems. So far, "Guanjun" has helped the Chinese team win two gold and one silver in snow events at this winter Olympic Games, including the gold medal of Freestyle Skiing men's air skills, the gold medal of Freestyle Skiing women's air skills and the silver medal of Freestyle Skiing air skills group. This indicates that the artificial intelligence system may have entered the stage of achievement landing in the field of competitive sports, and is expected to expand to more fields in the future.
