alphago is gonna lose

apparently the euro champion played a really amateurish game against alphago

lee sedol will crush alphago under his goban

that was six months ago though. i'm sure it's improved quite a lot since then. as of last week bookies were giving about 1:1 odds incredibly.

here's an annotated view of one of the games with commentary by some other presumably good player analyst:

here's some ppl talking about alphago's play:

thanks for the link, always neat to see a person who knows what they're talking about poke at the game

it definitely feels like google overstepped challenging the World's Greatest Go Master, but tbh in the last couple months the deep dream stuff is doing things (esp. the style transference stuff) i never thought would be possible so

so people might be interested in what it means when they see things like "9dan" or "9p" like in that video's splash screen

go has a ranking system, kind of like chess does, except with three distinct classes that have numerical ranks within them
amateur players are known as "kyu", with a number that usually begins around 20 or so. so if you're totally new, you'd say you're 20kyu or abbreviate it as 20k. this number decreases the better you get, until you're 1kyu. usually there's no real body to evaluate kyu players, so it's more or less done by self-estimation
once you pass 1kyu, you become 1dan, or 1d. "dan" players are advanced but not professional, and are usually given the rank of dan by their region's go association after passing tests and/or tournaments. from here, the number goes up to 7dan to 9dan, depending on the group
past/parallel to that, there is the professional group, which are also referred to as "dan", although some distinction is made in abbreviation by saying that a low-ranked professional is 1p. again, this goes up to 9p

lee sedol, the player tonight, is 9p. this means he is amongst the best of the best, and analogous to a chess grandmaster

I feel as if there's some kind of joke in Google Research pitting their wits against a game with roughly a googol squared possible states but I can't get to it, so

imagine all the atoms in the visible universe. now replace each of them with a whole universes worth of atoms. that number of atoms is still orders of magnitude smaller than the number of legal go positions

yup, and that's legal states. illegal states is something to the order of 10^172, so only about 1% of all theoretical states are considered legal


Symbolic Butt posted:

a good rule of thumb that I learned with Peter Norvig (my computerman hero) with dealing with brute force nowadays is:

brute forcing 1 million to 100 million states (10^6 - 10^8) is trivial, modern computers can do it in a matter of seconds, maybe a minute

at billion states (10^9 - 10^11) it starts getting a little harder, like maybe it'll be like 20 minutes to 3 hours, something like that. if you really want an answer in the worst case you could leave your computer running it for a week? no big deal

now trillion states (10^12 - 10^14)... you're just hosed. you'd need to leave your computer running it for hundreds of years, it's just hopeless. even with the best computers on earth at this point it's still tough as poo poo with a pure brute-force approach.




this board game has around 10^170 possible states

btw I didn't give the number for the actual problem of playing the game which involves searching through the game tree :ssh:

Still better than android clock

quote:

I enjoyed this game and look forward to the next. I think I failed on the opening layout so if I do a better job on the opening aspect I think I will be able to increase my probability of winning

i take that to mean "i didn't really have an anti-computer strategy for an opponent that good" which kinda makes sense cause it's not like anyone has ever needed one before. kasparov said pretty much the same thing after deep blue stomped him in that first game, didn't he?

there was some weirdness with Kasparov's games where he massively overestimated how good deep blue was or something because if a weird endgame and it really threw him

decent writeup here

https://gogameguru.com/alphago-defeats-lee-sedol-game-1/

e:

quote:

“I was so surprised. Actually, I never imagined that I would lose. It’s so shocking.”

“Regarding the game, I got off to a bad start and AlphaGo played well right until the end.”

“Even when I was behind, I still didn’t imagine that I’d lose. I didn’t think that it would be able to play such an excellent game.”

“I heard that the DeepMind CEO Demis Hassabis said that he respects me as a Go player, but I have great respect for both of them [referring to Demis Hassabis and Eric Schmidt] for making this amazing program.”

“I also respect all the programmers who helped to make AlphaGo.”
