Lee Sedol says not defeat of humans after historic Go match with AlphaGo

South Korean Go grandmaster Lee Sedol said Saturday that it was "not a defeat of humans" after his third consecutive loss in a historic five-game match with Google's computer program AlphaGo.

"It's just a defeat of Lee Sedol, but not a defeat of humans," Lee told a press conference after he lost three games in a row in the "century of the match," which was regarded as a representative fight between human brains and artificial intelligence (AI).

After more than four hours of play, Lee resigned as the computer program developed by Google's London-based AI arm DeepMind maintained an unassailable lead.

The 33-year-old grandmaster, who has won 18 world championships for 21 years of his professional career, said AlphaGo is an amazing program but has yet to rise to a level of God.

For sure, AlphaGo seemed to have weak points, which were shown in the first two games as well, Lee said.

Touching on why he was defeated for the third time, Lee said he lacked a capability of overcoming such a severe sense of pressure and burden he has never felt before.

Lee expressed his apology for the defeats in vain, saying that he showed powerless plays despite public hopes for his plays and wins.

In hindsight, it would have been difficult for him to win the first match as he had many misjudgments on AlphaGo's capability, while he missed many chances in the second match, which he played according to his strategy in an early phase, Lee said.

Though the final winner was already selected, AlphaGo's real capability could be evaluated more accurately in the fourth and fifth matches, Lee said, hoping for more attention to the remaining games.

The five-game match, which kicked off on Wednesday, will last until next Tuesday. The next match will be held on Sunday in Seoul. Enditem
