Let me add my congratulations to the chorus. Well done! I'm due for a sabbatical next year. I had been joking, "It sure would be good timing if someone cracked Go right before that started. Then I'd have plenty of time to pick a new research topic." It looks like AlphaGo has provided. On Wed,

You must be kidding about Lee Sedol. Yes, he is not as dominating as before. (is it because he is weaker or because the other ones got better?) But he is still #3 in Korea having only dropped there this month, being #2 for most of the last year. (btw overtaken by Park Younghoon, who is not really

Ingo and all, Why you care AlphaGo and DCNN so much? Surely DeepMind team did a big leap but the big problems, such as detecting double-ko and solving complex positions are left unchanged. Also it's well known that to attack these weakpoint of MCTS bots, the opponents have to be strong

[Computer-go] AlphaGo MCTS & Reinforcement Learning?

2016-01-31 Thread Greg Schmidt
The articles I've read so far about AlphaGo mention both MCTS and RL/Q-Learning. Since MCTS (and certainly UCT) keeps statistics on wins and propagates that information up the tree, that in and of itself would seem to constitute RL, so how does it make sense to have both? It seems redundant

Explaining why the move is good in human terms is useless goal. Good chess programs cannot do it nor it is meaningful. As the humans and computers have vastly different approach to selecting a move then by the definition have reasons for moves. As an example your second item 'long-term aji', For

Why would they water down their Lee Sedol game by announcing another game before their big game has even happened? No matter if that game would be before or after. Sounds like an awful PR strategy. 2016-02-01 2:51 GMT+01:00 uurtamo . : > It might even be interesting if it took

Just in case that no one knows it. Ke Jie has publicly announced that he is willing to play against AlphaGo, even without any prize money. Since Ke Jie is absolutely the current No.1, it would be a good choice to have another match with Ke Jie, time permitting, no matter AlphaGo wins or loses
