I've read some articles in Korean press that suggested AlphaGo team picked Lee as their match and not Ke Jie (currently #1 ranked, 19 years young) because there's a lot more public records of Lee's plays over his much longer pro career (nearly 20 years now). Thus more material for AlphaGo to train with and against.
So it's not totally arrogant of Ke Jie to suggest he could beat AlphaGo. AlphaGo has not much 'experience' in dealing with Ke Jie.
And Lee winning of game 4 shows a human is still indeed more capable than any AI. He basically reprogrammed his game on his own. Sorta.
- kybernetikos 11y agoThat was specifically discussed in the after match conference today. Demis said that it wasn't trained specifically against Lee but was trained against strong amateurs on the Internet initially before playing against itself. He said that even if they'd wanted to, alpha go requires a much larger number of games than are available by Lee Seoul to train so it wouldn't have been possible anyway.
- phatfish 11y agoIt was discussed pre-match for game 2 or 3 as well, and Lee's games were described as "a drop in the ocean" I believe. Came up because of an assertion from the interviewer that chess AI had been trained against it's opponent specifically.
- Angostura 11y agoErr, so if AlphaGo wins game 5, does that show 'an AI is still indeed more capable than any human?'
- silasdavis 11y agoExactly. The faint whiff of bullshit.
- bluecalm 11y agoAnother reason could be that Lee is a much bigger name in go than Ke Jie. Sure, Ke Jie is stronger now but Lee was a dominant/top player for a long long time.
- CydeWeys 11y agoKe Jie just happens to be #1 right now. Lee Sedol is more impressive in that he's been a world-class Go player for much longer. Twenty years from now, if Ke Jie is as dominant as Lee Sedol is now, then he'd be a good pick then. But either way it's not a big deal; there's not that much daylight between the two, so picking the more famous and well-known one to go up against is a safe bet. Personally I want to see a discussion game with the top Go experts (including both Lee Sedol and Ke Jie amongst others) competing against the next version of AlphaGo, in a game with much longer time limits.
- fspeech 11y agoI don't think top pros view it that way. He is of a new generation that play thousands of games over the internet; that study the game socially, while Lee is much more a loner. Whether Ke Jie will dominate as much as Lee did will say more about the strength of his competitors than his strength vs Lee.
- Cacti 11y agoMany of the reinforcement learning techniques require data sets in the billions to make much sense of it all. This is likely the reason why the AI had to play against itself so much, because there simply wasn't enough data in general, even including all recorded games. So Lee's games are sort of a drop in a bucket as far the performance of the AI goes.
