I was thinking the same thing. You can easily equip the value network with several outputs, corresponding to several settings of komi, then train as usual. The issue with Japanese rules is easily solved by refusing to play under ridiculous rules. Yes, I do have strong opinions. :) Álvaro. On

I guess that 1 point in such a game matters to the evaluation function. Pretty fascinating. Can you not train for the two different rulesets and just pick which at the beginning? Ignoring Chinese versus Japanese, just training on komi? Or is the problem of Japanese rules the whole issue? (I.e not

How does Zen know it's playing a Japanese rule game? Can it be set to play a Chinese rule game and hope to converge at the end? On Mar 21, 2017 8:03 AM, "Hideki Kato" wrote: > The value network has been trained with Chinese rules and 7.5 > pts komi. Using this for

Why can't you reuse the same self played games but score them with a different komi value ? The policy network does not use the komi to choose its moves so it should make no difference. > On 21/03/2017 21:08, David Ongaro wrote: >>> But how would you fix it? Isn't that you'd need to retrain

Hi, now we see how clever the DeepMind team was (and likely still is). In both matches (against Fan Hui and Lee Sedol) Chinese rules were applied. Some years ago I performed experiments with Monte Carlo search in special non-zero sum games (with

The value network has been trained with Chinese rules and 7.5 pts komi. Using this for Japanese and 6.5, there will be some error in close games. We knew this issue and thought such chances would be so small that postponed correcting (not so easy). Best, Hideki Pawe Morawiecki:
