Go master Cho Chikun triumphed Wednesday in his final game against DeepZenGo, a Japanese artificial intelligence system, to win the three-game series 2-1.
Cho, 60, has won 74 titles, the largest number in Japan, over a long career. He defeated DeepZenGo with the 167th move in the third game of the series, which was played on even terms with no handicaps.
DeepZenGo uses deep learning and other advanced technologies. It is being developed with support mainly from Dwango Co., a video-sharing website operator, and the University of Tokyo.
“I felt as if I was playing with a human, because (DeepZenGo) has both strong and weak points,” Cho said after the final game.
DeepZenGo “suffered a crushing defeat today,” developer Hideki Kato, 62, said. But he added, “I know exactly what needs to be fixed.”
In March, Google DeepMind’s AlphaGo AI setup won its five-game series 4-1 against South Korean Go master Lee Sedol.
