Hi all, I am the first author of Facebook Go AI. Thanks for your interest! This is the first time I post a message here, so please forgive me if I mess up with anything. 1. The estimation of 1d-2d is based on the win rate of free game in the last 3 months (since darkforest launched in Aug). See

Perhaps bots in the style of Darkforest would be good candidates to win the Handicap-29 prize... http://www.althofer.de/handicap-29-prize.html Ingo.   *** Gesendet: Dienstag, 24. November 2015 um 07:00 Uhr Von: "David Fotland"

[Computer-go] Why do Facebook use DNN next-move predictors? Shouldn't they use next-move generators?

2015-11-24 Thread Harald Korneliussen
When I read about Facebook's DCNN-using go program, I remembered another paper that I'd come across on arxiv, namely "How (not) to train your generative model: scheduled sampling, likelihood, adversary?" by Ferenc Huszar (http://arxiv.org/pdf/1511.05101.pdf). A lot of that paper went over my head

2015-11-24 Thread Igor Polyakov
If you train your neural network on pro games, pros never play out ladders that end up in capture, so when a ladder situation happens and it gets played out, the running group is always safe. This is not the case always, but you'd need to specifically play out the ladder to check. On
