Update default net to nn-1ee1aba5ed4c.nnue Created by retraining the master net on a dataset composed by: - adding Leela data from T60 jul-dec 2020, T77 nov 2021, T80 jun-jul 2023 - deduplicating and unminimizing parts of the dataset before interleaving Trained initially with max epoch 800, then increased near the end of training twice. First to 960, then 1200. After training, post-processing involved: - greedy permuting L1 weights with https://github.com/official-stockfish/Stockfish/pull/4620 - greedy 2- and 3- cycle permuting with https://github.com/official-stockfish/Stockfish/pull/4640 python3 easy_train.py \ --experiment-name 2048-retrain-S6-sk28 \ --training-dataset /data/S6.binpack \ --early-fen-skipping 28 \ --start-from-engine-test-net True \ --max_epoch 1200 \ --lr 4.375e-4 \ --gamma 0.995 \ --start-lambda 1.0 \ --end-lambda 0.7 \ --tui False \ --seed $RANDOM \ --gpus 0 In the list of datasets below, periods in the filename represent the sequence of steps applied to arrive at the particular binpack.
