Since there was a thread on Microsoft's new AI taking a temporary leave, I figured some users might find this article interesting, there's been a victory on the AI front.

A new aggressive Go AI is crushing through professional competition. It won a 3-0 shutout against one of the best Go players in South Korea.

Quote
Move after move was exchanged and it became apparent that Lee wasn’t gaining enough profit from his attack.
By move 32, it was unclear who was attacking whom, and by 48 Lee was desperately fending off White’s [AlphaGo's] powerful counter-attack.

I can only speak for myself here, but as I watched the game unfold and the realization of what was happening dawned on me, I felt physically unwell.

Generally I avoid this sort of personal commentary, but this game was just so disquieting. I say this as someone who is quite interested in AI and who has been looking forward to the match since it was announced.

One of the greatest virtuosos of the middle game had just been upstaged in black and white clarity. AlphaGo’s strength was simply remarkable and it was hard not to feel Lee’s pain

The last two games will be played regardless of the fact that AlphaGo won. The AI is extremely cunning and makes no mistakes.

EDIT: Just read that games four and five already took place. Lee won game four but game five ended with AlphaGo winning.

EDIT: EDIT: Just read the Wikipedia article on the match, found something interesting:

Quote
Prior to 2015,[11] the best Go programs only managed to reach amateur dan level.[12] On the small 9×9 board, the computer fared better, and some programs managed to win a fraction of their 9×9 games against professional players. Prior to AlphaGo, some researchers had claimed that computers would never defeat top humans at Go.[13] Elon Musk, an early investor of Deepmind, said in 2016 that experts in the field thought AI was 10 years away from achieving a victory against a Go top professional player.[14]

The match AlphaGo versus Lee Sedol is comparable to the 1997 chess match Deep Blue versus Garry Kasparov. There IBM's Deep Blue computer's defeat of reigning champion Kasparov is seen as the symbolic point where computers became better than humans at chess.[15]

AlphaGo is most significantly different from previous AI efforts in that it applies neural networks, in which evaluation heuristics are not hard-coded by human beings, but instead to a large extent learned by the program itself, through tens of millions of past Go matches as well as its own matches with itself. Not even AlphaGo's developer team are able to point out how AlphaGo evaluates the game position and picks its next move. Monte Carlo tree search is also used in a major way to improve the reasoning efficiency of the program.

Go is a Chinese strategy board game, the aim is to surround more territory than your opponent. Creating AI to play Go is considerably harder than creating one for Chess. The strategy involved in a game of Go is much more complex than chess, with a game of Go being able to have 10^170 moves whereas Chess is only 10^120.

What's go

Not an AI, but neat.
