European Champion of the board game Go has defeated the Google artificial intelligence program.
The game is of Chinese origin and is tougher than chess of the computers because there are multiple ways the game Go can be played. The game has beaten the rival games to total destruction.
An expert stated it as a breakthrough for AI with considerable consequences.
The details of the techniques were mentioned in a publication of a scientific journal and it was formally announced in the paper. The chief executive had earlier stated that he had its own project AI which was closer to beat Go.
He also added that his product was not ranked on a ‘professional level’ but was regarded as an “advanced amateur” player.
WHAT IS GO?
Go is dated a thousand years back to the Chinese dynasty.
Players can surround their opponents using their own black-and-white pieces of stones on a grid.
Demis Hassabis is the chief executive of DeepMind. He stated that the AlphaGo software was created from a three-stage process. The process began with making it analyse 30 million moves from games played by humans.
“It starts off by looking at professional games,” said Demis Hassabis
“It learns what patterns generally occur – what sort are good and what sort are bad. If you like, that’s the part of the program that learns the intuitive part of Go. It now plays different versions of itself millions and millions of times, and each time it gets incrementally better. It learns from its mistakes. The final step is known as the Monte Carlo Tree Search, which is really the planning stage. Now it has all the intuitive knowledge about which positions are good in Go, it can make long-range plans.” Demis Hassabis added
“Many of the best programmers in the world were asked last year how long it would take for a program to beat a top professional, and most of them were predicting 10-plus years. The reasons it was quicker than people expected was the pace of the innovation going on with the underlying algorithms and also how much more potential you can get by combining different algorithms together.” Demis Hassabis
Rules of Go are simpler than that of chess but a user has 200 choices to make in moves compared to just 20 in chess. .
According to DeepMind’s team, there are more possible positions in Go than atoms in the universe
The game relies on human instinct and it can be very difficult to identify the winner.
