Google’s AlphaGo Defeats Chinese Go Master in Win for A.I

AlphaGo already won the first game, which 5 years ago would have been considered impossible. It is basically over. Google can pour an order of magnitude more computing power at the algorithm to boost its performance if they choose too.

The question of performance as a function of computing power is an interesting one. Demis Hassabis claims that the returns are diminishing quickly when going above the system they are using. In fact Alpha Go Ke Ji uses 10 times less power than Alpha Go Lee Sedol, though the architecture has changed to using Google's own TPUs, so it's not an easy comparison.

In either case Alpha Go Ke Ji is said to be 3 stones stronger than Alpha Go Lee Sedol which the team claims comes nearly completely from algorithm improvements.

Google has stated previously that the Lee Sedol variant also used TPUs.

I suppose that invites the next challenge, a machine that can defeat a human with no more power consumption than a meat brain uses.
