Search Search Google DeepMind computer beats Go champion Lee Se-dol in shock 4-1 victory South Korean professional Go player Lee Sedol, right, puts the first stone against Google's artificial intelligence program, AlphaGo, during the Google DeepMind Challenge Match in Seoul, South Korea / AP Some had thought that Mr Lee's clawing back of the fourth game could indicate that he was learning how the computer worked – but the final game ended in a victory for AlphaGo 6169789578 Click to follow The Independent Tech Google’s Go-playing computer has definitively beaten the best human in the world, finishing a pioneering match at 4-1.
 For the past week, AlphaGo has been playing grandmaster Lee Sedol, one of the top Go players in history.
 The victory has been hailed as a huge leap forward for artificial intelligence systems of the kind built by DeepMind, Google’s artificial intelligence team.
 The ancient Chinese board game had been seen as too complex for computers to master.
 Just months ago, artificial intelligence experts said that we were at least 10 years from creating a computer powerful enough to beat the best humans at the game.
 But Go fans across Asia were astonished when Lee, one of the world's best Go players, lost the first three matches.

 It has created robots for DARPA, the US' military research company Google has been using similar technology to build self-driving cars, and has been pushing for legislation to allow them on the roads The DARPA Urban Challenge, set up by the US Department of Defense, challenges driverless cars to navigate a 60 mile course in an urban environment that simulates guerilla warfare Deep Blue, a computer created by IBM, won a match against world champion Garry Kasparov in 1997.
 The computer could evaluate 200 million positions per second, and Kasparov accused it of cheating after the match was finished Another computer created by IBM, Watson, beat two champions of US TV series Jeopardy at their own game in 2011 Apple's virtual assistant for iPhone, Siri, uses artificial intelligence technology to anticipate users' needs and give cheeky reactions Xbox's Kinect uses artificial intelligence to predict where players are likely to go, an track their movement more accurately Lee beat AlphaGo in the fourth match.
 He said he had found weak points in Google DeepMind's artificial intelligence programme which showed the machine was not infallible.
 Some had thought that could mean that Lee would go on to win the fifth game, too, and that AlphaGo’s victory in the first three games was the result of its eccentric and non-human playing style.

 Google wants to use AlphaGo beyond games, ultimately to solve real-world problems.
 The computer has been widely seen as proof that artificial intelligence machines could go on to master characteristics that were previously thought to belong only to humans, like intuition.
