Re: Is this SF NN almost like 20 MB book?

Just NN eval definitely isn't an opening book. But what about policy head? I definitely consider it book ish , Leela being very deterministic also supports it. NNUE just outputs a single eval. No policy. Also: https://github.com/dkappe/leela-chess-weights/wiki/Leela-is-an-opening-book-nonsense I wa...

Re: Stockfish NNUE SV Tests

At this time control (30 sec+ 0.5 ) all latest Stockfish NNUE versions easily passed +100 elo barrier against Stockfish 11 dev. At 1 min + 0.5 sec time control all latest Stockfish NNUE versions easily passed +90 elo barrier against Stockfish 11 dev. But in my tests the performance of latest Stockf...

Re: NNUE at LTC

ELO compression is the biggest factor probably. Take FastGM.de Difference between SF11 and Eth 12.25 is 253 elo at 60+0.6. At 60m+15s it's 170 elo. That doesn't mean Eth scales better than SF11, it's just less likely to blunder away a draw. You can replace Ethereal with most engines on that list. Th...

Re: SF-NNUE going forward...

Rough maths suggests he has at least 1000 cores to do that. If we call several = 5 5 billion fens a day = 50000 fens per second, which if he samples at 25% implies 12500 games per second. One game every 0.08 ms. For massively fast bullet that needs 1000 cores at least, I think. 1000 cores would all...

Re: SF-NNUE going forward...

Haven't read all of this thread so excuse me if it was already mentioned: tttak's fork has a lot of different architectures to try out. I'm interested in the "Gameply40x4" one which effectively holds 4 NNs in one file which get used sequentially switching every 40 plies until the 4th is loaded. Thi...

Efficiently-Updating Neural Network. It's backwards because of some wordplay in Japanese, if I remember correctly.
