I was at the 2003 match of Garry Kasparov vs Deep Junior -- the strongest chess player of all time vs what was at that point the strongest chess playing computer in history. Kasparov drew that match, but it was clear it was the last stand of homo sapiens in the man vs machine chess battle. Back then, people took solace in the game of Go. Many boldly and confidently predicted we wouldn't see a computer beat the Go wor…

I've never felt playing against what is suppose to be an entire room of machines (wether Deep Blue or Watson) to be fair. What would be fair is to limit the total mass of the computer to say 200kg and leave it at that. What is effectively happening is AlphaGo is running on a distributed system of many, many machines. Even Watson took an entire room. Google is paying a premium to push AlphaGo to win.

Seems like a pretty arbitrary limitation. 70 years ago Colossus filled an entire room, now it can be emulated on a Raspberry Pi. The really groundbreaking part is the algorithm.

Has Google talked about the amount of computing resources they're throwing at this match? I'd be very interested to know.

1202 CPUs and 176 GPUs apparently

edit: according to the livestream

This is my generation's Gary Kasparov vs. Deep Blue. In many ways, it is more significant. Several top commentators were saying how AlphaGo has improved noticeably since October. AlphaGo's victory tonight marks the moment that go is no longer a human dominated contest. It was a very exciting game, incredible level of play. I really enjoyed watching it live with the expert commentary. I recommend the AGA youtube chann…

Yep, terrific commentary by Myungwan Kim 9p on the AGA channel. For the folks who aren't as familiar with the game, how did you find the commentary (for any channel)? What would you be interested in hearing for events like these?

I watched the commentary on Youtube and it was fantastic! I don't play go myself but I was glued to the screen the whole way. I particularly enjoyed how the commentators demonstrated why the moves made sense by playing theoretical future moves right on the board they had up.

I don't think AGA had the rights to stream and comment this match.

Where did you find this 9p AGA commentary? I don't see it in the list of AGA videos on youtube.

In case you're not aware, AlphaGo's key component is based on the same type of Deepmind system that learned to play dozens of Atari games, to superhuman levels, by watching the pixels, without any programmatic adaptation to the particular Atari game. At least the version of AlphaGo that played in October was far less specialized for Go than Deep Blue was for chess. Demis Hassabis says that next up after this is getti…

That's incorrect. The features that AlphaGo uses are not pixel level features, but board states - and the architecture between AlphaGo and the Atari network is completely different. It's still an incredibly achievement - but it's important to be accurate.

For AlphaGo, a "pixel" is a point on the board. It uses essentially the same convolutional neural networks (CNNs) that are in state-of-the-art machine vision systems. But yes, the overall architecture is rather different from the Atari system, due to the integration of that CNN with Monte Carlo Tree Search.

> The real world doesn't follow formal game rules. Really? Why not?

Infinite state/belief/world space. Infinite action space. It's not so much that there aren't rules (there are - physics), it's that the complexity of the full set of rules is exponential or super-exponential.

You can do math with continuous and infinite dimensional spaces.

It was live streamed and the archive is now up on The Official AGA Youtube Channel at: AlphaGo ?p vs Lee Sedol 9p, 0400 UTC (8pm PST)[1]

I know absolutely nothing about Go, and I enjoyed the deepmind channel and found the commenting very good. I was actually thinking about playing a game with another total noob, just for fun, since the rules can be explained in 1 minute (unlike chess).

Chess rules can be explained in 1 minute - you just have to talk really, really fast.

Chess engines and processing power have since then advanced to a point where my phone can now reliably beat Carlsen. There is no reason to suppose Go is different in that respect. In 10 years, DeepMind will fit into a phone.

A top smartphone chess program can beat pretty much all but the best few players in the world. Do you think it's fair to pit a 150 gram device against a 70 kg human?

Although a fairer comparison would be against 1 kg of brain. Comparing against a human would need to include all the infrastructure for the device such as energy production or the manufacturing equipment required. But nevertheless, fitting so much computing power in such a small device is a great achievement.

Not really, the brain to operate also needs all the other systems. Just as a CPU needs all the other parts to function. And including the manufacturing equipment is just as false, in the sense that you would have to include his mother (as biological manufacturing)
