Commit ID 9ee58dc7a75d7cdc09935f8782e927bb19700afe
Author Joost VandeVondele

Update default net to nn-3678835b1d3d.nnue New net trained with nnue-pytorch, started from the master net on a data set of Leela (T60.binpack+T74.binpck) and Stockfish data (wrongIsRight_nodes5000pv2.binpack), available as a single interleaved binpack: https://drive.google.com/file/d/12uWZIA3F2cNbraAzQNb1jgf3tq_6HkTr/view?usp=sharing The nnue-pytorch branch used is https://github.com/vondele/nnue-pytorch/tree/wdl, which has the new feature to filter positions based on the likelihood of the current evaluation leading to the game outcome. It should make it less likely to try to learn from misevaluated positions. Standard options have been used, starting from the master net: --gpus 1 --threads 4 --num-workers 4 --batch-size 16384 --progress_bar_refresh_rate 300 --smart-fen-skipping --random-fen-skipping 12 --features=HalfKAv2_hm^ --lambda=1.0 Testing with games shows neutral Elo at STC, and good performance at LTC: STC: https://tests.stockfishchess.org/tests/view/619eb597c0a4ea18ba95a4dc ELO: -0.44 +-1.8 (95%) LOS: 31.2% Total: 40000 W: 10447 L: 10498 D: 19055 Ptnml(0-2): 254, 4576, 10260, 4787, 123 LTC: https://tests.stockfishchess.org/tests/view/619f6e87c0a4ea18ba95a53f ELO: 3.30 +-1.8 (95%) LOS: 100.0% Total: 33062 W: 8560 L: 8246 D: 16256 Ptnml(0-2): 54, 3358, 9352, 3754, 13 passed LTC SPRT: https://tests.stockfishchess.org/tests/view/61a0864e8967bbf894416e65 LLR: 2.94 (-2.94,2.94) <0.50,3.00> Total: 29376 W: 7663 L: 7396 D: 14317 Ptnml(0-2): 67, 3017, 8205, 3380, 19 closes https://github.com/official-stockfish/Stockfish/pull/3808 Bench: 7011501
