SOUTH KOREAN Go grandmaster Lee Se-dol has won his first game against AlphaGo, Google’s artificial intelligence (AI) computing system, after losing three straight in last week’s historic match.

    AlphaGo had already claimed victory in the best-of-five contest, a test of artificial intelligence closely watched in Asia and across the tech world. But Lee yesterday clawed back a degree of pride for himself and the millions of people who watched the match online.

    The gathered Korean reporters and photographers cheered and applauded when AlphaGo resigned roughly five hours into the game. As Lee showed, machines are by no means infallible.

    AlphaGo’s dominance in the first three games was notable because no machine had previously beaten a top human player at Go. With AlphaGo taking a three-games-to-none lead in the best-of-five contest — Game Four began with its own drama. As match commentator Chris Garlock said just before the game began, one big question remained: Does AlphaGo have a weakness? (SD-Agencies)
