A couple background info:
For people outside of Go community, Ke Jie is the new star of Go, currently Jie's Elo rating is #1, http://www.goratings.org/ http://www.goratings.org/, Lee Sedol is #4. Media touted Lee Sedol as the greatest player of past decade, it was true couple years ago but Lee Sedol has been clearly in decline in recent years (as seen in the Elo rating).
2) Ke Jie is 19, at the peak age of his game. Lee Sedol is 33 and is seemingly in decline in his game, hence the 2:8 record vs. Ke Jie.
3) Ke Jie probably wanted to be challenged since he is the current world's #1 Go player. Sure there aren't much differences in terms of skill levels between top Pro 9 dan players but challenging a current world's #4 player is different from challenging a current world #1 player, isn't it?
It's a shame that the Western world doesn't know Ke Jie well(as his wikipedia page has very limited info and his award records.)[1] But these are moot points. After the 2nd defeat, it's increasingly clear that AlphaGo will defeat human player - it's a matter of time or a matter of a couple more games.

- statsaresimple 11y agoNot so sure about the extra mile. It could happen that the AI couldn't be able to go beyond a certain level. That is this AI could be walled. We have a wonderful opportunity to see an example in which current AI is measured to be near but not far from best human competence.
- devy 11y ago> It could happen that the AI couldn't be able to go beyond a certain level. That's your wishful thinking. As we've seen the matches with Fan Hui in the past, unfortunately and fortunately, the CNN will improve drastically game after game and making less mistakes whereas human always do at a certain level. Another big point I want to point out is human emotion and state of the mind. With 0:2, Lee Sedol lost his confidence ("speechless" in his own words) [1] and quite possibly increasing fear of losing in a landslide 0:5. Losing confidence and fear of losing are VERY TERRIBLE things in any competitive sports.

- statsaresimple 11y agoit is very interesting to measure at what rate AI improves. If the AI can improve a lot, a very interesting problem is to develop a scale or elo for measuring this progress. I am more interested in what lesson we can take home from this match, I don't have a wish here. We have many thinks to learn about this. In a situation of great uncertainty about the pace at with AI can improve its capabilities, measuring the velocity or rate of change can gives a hint about the future and applications of this new technology.
- FD3SA 11y agoIt puts it into perspective that he's 19. Some healthy youthful arrogance. He doesn't seem to understand that 6 months to a deep neural net running on 200 GPUs and 1000 CPUs is equivalent to a millenia for a human player. He will be destroyed just like Lee Sedol, but its good for him to believe he can win so he puts up a fight.
- antaviana 11y agoAgreed. Each 100 point of ELO diference translate into a 2 times stronger player. The one to beat is Ke Jie because he is currently two times stronger than Lee Sedol.
- kriro 11y agoI prefer the marketing narrative of beating a top pro then challenging the #1...or better yet have said #1 more or less ask for the challenge himself. It's more impact than going for the #1 directly and also allows for some extra optimization cycles.
