Re: [Computer-go] AlphaGo won first game!

Hi! I think the technique of hashing move pairs from the search tree and reuse them in the playouts if the context matches, could plausibly be the major improvement of Alphago that we witnessed today. Another thing I noticed is that Alphago does not use any statistics from the playouts

Re: [Computer-go] AlphaGo won first game!

In my opinion, the thing that programs do worst is ko. Lee did not play any kos, except one minor irrelevant one in the lower left. This game was so simple that the program could accurately model the whole board. If Lee wants to win, he needs to start 2 or 3 simultaneous kos. Michael Wing

Re: [Computer-go] *****SPAM***** Re: AlphaGo won first game!

Yes, I think the programs will have similar biases. In this game Sedol had some groups that were alive, but needed correct responses to stay alive. Even though the pro's stones won’t die, the playouts sometimes manage to kill them. This makes the program think it is more ahead than it

Re: [Computer-go] *****SPAM***** Re: AlphaGo won first game!

I predicted Sedol would be shocked. I'm still routing for Sedol. From Scientific American interview... Schaeffer and Fotland still predict Sedol will win the match. “I think the pro will win,” Fotland says, “But I think the pro will be shocked at how strong the program is.” > > P.S. Lee

Re: [Computer-go] AlphaGo won first game!

Congratulations to AlphaGo people! Are there strong humans who have an opinion, on whether this advantage at move 26 is real ? In pro games, does it happen often that there is a clear advantage at move 26 ? -- = "I will never sign a

Re: [Computer-go] AlphaGo won first game!

Congratulations, Aja and David! Very remarkable win! Pasky, It's too early to conclude any, I think, because no records of losing games have been published, ie., no weakpoints of AlphaGo are open. I believe that the essential problems which come from current MCTS (bottom-up) framework, such

Re: [Computer-go] AlphaGo won first game!

Aya also thought AlphaGo was ahead 55% - 65% most of game. But it is because Aya thought Black N-18 group is 65% alive at move 75. This Black must live 100%. So I think MCTS tend to think White is ahead. I'm curious whether AlphaGo understands this group is over 80% alive. Thanks, Hiroshi

Re: [Computer-go] AlphaGo won first game!

I found Michael Redmond's commentary very good. Helped a weak player like me understand what was going on, but occasionally went over my head, which I'm sure others appreciated. He came across as a class act. His partner, on the other hand, (I forget his name) was more of a hindrance to the

You may also want to check out AGA's commentary by Andrew Jackson and Myungwan Kim. They don't run out of magnetic stones. https://www.youtube.com/watch?v=YZPKR7HzM_s On 09/03/2016 16:13, Richard Lorentz wrote: > I found Michael Redmond's commentary very good. Helped a weak player > like me

Btw, is there any information on what hardware AlphaGo is running. And how does it compare to the version used against Fan Hui? 2016-03-09 9:31 GMT+01:00 David Fotland : > Many Faces thought alpha go was ahead most of the game. It looked to me > like the turning point

Re: [Computer-go] AlphaGo won first game!

Many Faces thought alpha go was ahead most of the game. It looked to me like the turning point was when Alphago cut in the center then gave up the two cutting stones for gains on both sides (but not so strong…). Congratulations Aja! I watched it at Google in Mountain View with about

Re: [Computer-go] AlphaGo won first game!

The amount of points AlphaGo was ahead is also meaningless because it started playing slow moves when it got ahead. After the big fights were finished it already knew it was going to win easily. On 2016-03-08 23:55, Marc Landgraf wrote: It was pointed out by Lee Sedol after the game and Kim

As Demis said during the press conference, it's roughly the same amount of hardware. On Mar 9, 2016 17:56, "Marc Landgraf" wrote: > Btw, is there any information on what hardware AlphaGo is running. And > how does it compare to the version used against Fan Hui? > >
