  Deep learning technology is making great progress in solving the challenging
problems of artificial intelligence, hence machine learning based on artificial
neural networks is in the spotlight again. In some areas, artificial
intelligence based on deep learning is beyond human capabilities. It seemed
extremely difficult for a machine to beat a human in a Go game, but AlphaGo has
shown to beat a professional player in the game. By looking at the statistical
distribution of the distance in which the Go stones are laid in succession, we
find a clear trace that Alphago has surpassed human abilities. The AlphaGo than
professional players and professional players than ordinary players shows the
laying of stones in the distance becomes more frequent. In addition, AlphaGo
shows a much more pronounced difference than that of ordinary players and
professional players.
