Google AI wins second Go game against top player

   
Lee Se-dol lost to Google's AI software for a second day in a row 
 

Google's AlphaGo artificial intelligence program has defeated a top Go player for a second time.

The five-game contest is being seen as a major test of what scientists and engineers have achieved in the sphere of AI.
After the match, Lee Se-dol said: "Yesterday I was surprised but today it's more than that, I am quite speechless.

"Today I feel like AlphaGo played a nearly perfect game," he said.
"If you look at how the game was played I admit it was a clear loss on my part."
Lee Se-dol is considered a champion Go player, winning numerous tournaments over a long, successful career.
In October 2015, AlphaGo beat the European Go champion, an achievement that was not expected for years.
A computer beat the world's chess champion in 1997, but Go is recognised as a more complex board game.
On Thursday, the Korea Times reported that locals had started calling AlphaGo "AI sabum" - or "master AI".

 

Lee Se-dol spoke to the press after the match

Three games remain, but Google only has to win once more to named the victor.
"Playing against a machine is very different from an actual human opponent," world champion Lee Se-dol told the BBC ahead of the first match.
"Normally, you can sense your opponent's breathing, their energy. And lots of times you make decisions which are dependent on the physical reactions of the person you're playing against.
"With a machine, you can't do that."
