New version chess engine: Lc0 BT4
LcZero - CEDR Rating=3683 vBT4: Big transformer 4. New network architecture which builds off of BT3 by adding two types of auxiliary heads, future heads and categorical value heads. The categorical value heads predict a distribution over values of q rather than a WDL outcome distribution, and the future heads predict the moves that will be played over the next two plies. The hope is that these heads will give additional information to the net to improve training speed. We've also fixed half-precision training, so this model will be larger. BT4 training started in mid-October and is expected to take a few months. It has 15 layers with 1024 embedding size, 32 heads per layer, and 1536 emb size, for roughly a doubling in size over BT3.

Hey, many thanks for this!! , i just have a question, do you know if in engines tounaments under Arena, if possible to make a competitions with many engines, cause i tried, and i invited 8 engines, and just the first two engines that Arena choose played all the games and without switch sides...
ReplyDeleteHow about writing to Arena Support describing what you have done and what engines you are using. But it works...so it must be your settings.
ReplyDeleteCould you tell me whats the correct settings to do engines tournaments in the right way?
