Computer beats human champion at Go

<< < (3/4) > >>

Schmee:
A long, long way away. That ability - to 'jump up a level' of reasoning - is kinda a big thing in AI research.

Masterpiece:
I know. I just watched Ex Machina, and it's a wonderful movie.

hedgie:
Update.  Game 1, the computer beats South Korea's Lee Se-dol.  There are four matches to go however, so maybe the human species will make a comeback.

Akima:
AlphaGo has defeated Lee Sedol 3-0! That is impressive.

Skewbrow:
The final score was 4-1. Lee Sedol won game four. He managed to get an edge in the center in the middle game. Shortly after it realized that it was losing Alphago started making really questionable moves. There have been fun speculations about why Lee Sedol's trick move worked. Apparently the correct continuation was difficult to spot and Alphago's Monte Carlo -approach missed it. Unfortunately I'm not informed enough about either Go or AI to understand the details. Anyway.

* Google reps (and enthusiasts at a go server I frequent) praised that one move by Lee Sedol, but other top ranked pros are not sure it really would have worked.
* Towards the end Alphago made moves that even I understand were no-hopers. Apparently its design does not allow it to look for moves that would give the strongest resistance (and best chance for a human opponent under severe time pressure to make mistakes)
My frogeye perspective observations.

* to some extent Lee Sedol underestimated his opponent before the first game. Apparently Alphago had learned a lot since its match against Fan Hui.
* In games two and three Lee Sedol didn't really have a chance. May be the pressure was too much?
* In games four and five, with the match already decided, Lee Sedol played better. The last game was very close even though he lost it.
Congrats to the team who programmed Alphago. Wonderfully implemented learning algorithms (and the approach of having two grids of computers - one working on the strategy, the other on the local tactics. If only Alphago could also explain why it played the way it did.
