Sony AI, showing artificial intelligence "GT Sophie"-- a portrait of defeating mankind with "Gentulimo"

　On Feb. 10, Sony AI said that artificial intelligence (AI), which took two years to train, had reached the level of beating the world's top human drivers in the "Granturimo SPORT". The Granturimo SPORT, developed by Polifoni Digital, is popular as a real racing game. The AI, named "GT Sophie", will beat the human level in the time test only if there are no other cars on the track in July 2021. But in October of the same year, virtual cars also beat humans in a crowded state on the track. GT Sophie is a new experiment that shows that AI can win games such as chess and go, which is considered to be the required area of human intelligence. Most AI systems learn the ability to recognize faces and detect spam through a system called deep learning that uses real-world data. GT Sophie uses a different technique, reinforcement learning (reinforcement learning). In this technique, AI is not trained and starts training in a state where he never knows what to do. GT Sophie competed repeatedly on the track, prompting them to come up with better results and slowly learn the game through a reward system designed by humans. GT Sophie's learning process is particularly difficult to understand the unwritten rules of the car, such as avoiding conflicts and not being able to improperly jump the queue of other drivers. "We all know how difficult it is for us to learn sports skills correctly," Peter Wurman, Sony's AI director, said in the video. "Don't be too aggressive and fall behind in front of other drivers, but race the car." Sony AI performed the simulation on a computer connected to more than 1000 game consoles "PlayStation4".
