Talk 2: \; Automatically Learning Heuristic Patterns for Computer Go
\;
Go is
an ancient two-player board game that originated in China
over th
ree thousand years ago. It plays an important role in
artificial i
ntelligence research\, being one of the few remaining games
in whi
ch human players still dominate the top computer programs. Top
Go
programs all use Monte-Carlo sampling. Many simulated games are
pl
ayed\, after which the move most often leading to a win is selected.
The moves within the simulated games are semi-random but biased by
both the results of previous simulations and heuristic knowledge.
\; \; \; This presentation focuses on a pattern-recogn
ition heuristic.
Certain local configurations of stones are recogn
ized as good (or bad)
by human Go players. We extracted patterns f
rom a collection of games
played by human experts. Playing moves s
uggested by our
automatically-learned good patterns performed as w
ell as expert hand
crafted patterns. Avoiding moves suggested by b
ad patterns does not
strengthen performance.
