South Korean battles computer

Lee Sedol
They compete in Chinese game

SEOUL, South Korea — Computers eventually will defeat human players of Go, but the beauty of the ancient Chinese game of strategy that has fascinated people for thousands of years will remain, the Go world champion said today.

South Korean Lee Sedol, a Go master who has won 18 international titles since he became a professional player at age 12, said the risk of human error means he may not win his match this week against Google’s artificial intelligence machine, AlphaGo.

“Because humans are human, they make mistakes,” the 33 year-old said a day before the first of the five games he is due to play against AlphaGo. “If there are human mistakes, I could lose.”

It was Lee’s first admission of his weakness against Google’s AI machine and also a dialing down of his confidence from two weeks ago, when he had predicted a 5-0 result in his favor.

After watching Google’s presentation of how AlphaGo works, Lee said he thought a machine might be able to imitate human intuition, even though the intuition may not be as sharp as a person’s.

A loss for Lee would be a historic moment for the AI community.

Human errors are not his only vulnerability.

Lee said that in playing against a machine, the absence of visual cues that human players use to read the reactions and psychology of their opponents puts him in unfamiliar territory.

“In a human versus human game, it is important to read the other person’s energy and force. But in this match, it is impossible to read such things,” Lee said.

Because the number of possible Go board positions exceeds the number of atoms in the universe, top players rely heavily on their intuition, said Demis Hassabis who heads Google’s DeepMind, the developer of AlphaGo.

This has made Go one of the most complex games ever devised and the ultimate challenge for the AI experts.
