DeepMind's AI beats world's best Go player in latest face-off

AlphaGo is at it again. Google DeepMind's Go-playing AI has defeated Ke Jie, the world's number one player, in the first of three games played in Wuzhen, China. The AI won by just half a point – the smallest possible margin of victory – in a match that lasted four hours and fifteen minutes. Though the scoreline looks close, AlphaGo was in the lead from relatively early on in the game. Since the AI favours moves that are more likely to guarantee victory, it doesn't usually trounce its opponents. In March last year, AlphaGo beat Lee Sedol, one of the world's top Go players, winning four out of five matches.
