Alpha GO |Google outdo Facebook in an AI (Artificial Intelligence) breakthrough by beating a Go champion.
ABOUT THE GAME
Go is a Chinese game dating back its origin to 2500 years ago. The rules of the game are simple: turn by turn Players place either black or white stones on the board, in order to take over the opponent’s stones or cover up the empty spaces in order to win the game. But the simplicity in the rules is in contrast with the complex nature of the game. There are more possible positions in Go than there are atoms in the universe. That makes Go one of the most complex board game of all time.
AlphaGo is a computer program developed to play the board game Go. In 2015, it became the first Computer Go program to beat a human Go player on a full-sized 19×19 board. In March 2016, it beat Lee Sedol a legendary GO player in a five-game match giving a final score of 4 games to 1 in favor of AlphaGo. This is the first time a computer Go program has beaten a professional player. In recognition of beating Lee Sedol, AlphaGo was honored with a 9-dan by the KBA(Korea Baduk Association).
The algorithm used for AlphaGo is based on machine learning in combination with tree search techniques, alongside lengthy training, both from human and computer play applying technologies based on neural network.
AlphaGo was initially trained to copy human play by attempting to match the moves of expert players from recorded historical games, using a database of several million moves. It was further trained by playing a large number of games against itself for further improvement.
AlphaGo’s style of playing favors higher chances of winning by less points over lesser chances of winning by more points.
Facebook has also been developing their own Go-playing software “DarkForest”, based on combining machine learning and tree search algorithm. Despite being a strong contender, it had not yet won against a professional human player.
Founded in 2011, by Demis Hassabis, Mustafa Suleyman and Shane Legg , DeepMind Technologies works in the field of artificial intelligence. Google acquired DeepMind in 2014 for reportedly $500 million after the negotiations with Facebook ended in 2013.
