nn-ae6a388e4a1a.nnue\n\nPart 1: PyTorch Training, linrock\n\nTrained with a 10-stage sequence from scratch, starting in May 2023:\nhttps://github.com/linrock/nnue-tools/blob/master/exp-sequences/3072-10stage-SFNNv9.yml\n\nWhile the training methods were similar to the L1-2560 training sequence,\nthe last two stages introduced min-v2 binpacks,\nwhere bestmove capture and in-check position scores were not zeroed during minimization,\nfor compatibility with skipping SEE >= 0 positions and future research.\n\nTraining data can be found at:\nhttps://robotmoon.com/nnue-training-data\n\nThis net was tested at epoch 679 of the 10th training stage:\nhttps://tests.stockfishchess.org/tests/view/65f32e460ec64f0526c48dbc\n\nPart 2: SPSA Training, Viren6\n\nThe net was then SPSA tuned.\nThis consisted of the output weights (32 * 8) and biases (8)\nas well as the L3 biases (32 * 8) and L2 biases (16 * 8), totalling 648 params in total.\n\nThe SPSA tune can be found here:\nhttps://tests.stockfishchess.org/tests/view/65fc33ba0ec64f0526c512e3\n\nWith the help of Disservin , the initial weights were extracted with:\nhttps://github.com/Viren6/Stockfish/tree/new228\n\nThe net was saved with the tuned weights using:\nhttps://github.com/Viren6/Stockfish/tree/new241\n\nEarlier nets of the SPSA failed STC compared to the base 3072 net of part 1:\nhttps://tests.stockfishchess.org/tests/view/65ff356e0ec64f0526c53c98\nTherefore it is suspected that the SPSA at VVLTC has\nadded extra scaling on top of the scaling of increasing the L1 size.\n\nPassed VVLTC 1:\nhttps://tests.stockfishchess.org/tests/view/6604a9020ec64f0526c583da\nLLR: 2.94 (-2.94,2.94) <0.00,2.00>\nTotal: 53042 W: 13554 L: 13256 D:
