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.

The Sting engines listing Marek Kwiatkowski as the author are either the lasiest clones ever, or Kwiatkowski is just a terrible coder that is incapable of even finding the author's signature line in the code. Download the engine and install it in whatever GUI you choose and the author that pops up is Tord Romstad and Marco Costalba. A word of advice Marek...while it is perfectly fine to clone open source material like Stockfish, you might want to change at least one line of code....oh wait....two lines of code. One line to make your "own" improvements and the second line to change the original author. What a joke!
