Google's AlphaGo beats world's best player in latest Go match

DeepMind's artificial intelligence AlphaGo has defeated Ke Jie, the world's number one player, in the first of three games of Go played in Wuzhen, China. The AI won by half a point – the smallest possible margin of victory – in a match lasting 4 hours and 15 minutes. Although the scoreline looks close, AlphaGo was in the lead from relatively early on in the game. Because the AI favours moves that are more likely to guarantee victory, it doesn't usually trounce opponents. In a press conference after the match, Ke said AlphaGo had learned from its recent victories against Go champions.
