Optimization of vondele's nn-33c9d39e5eb6.nnue using SPSA https://tests.stockfishchess.org/tests/view/60ca68be457376eb8bcab28b Setting: ck values are default based on how large the parameters are The new values for this net are the raw values at the end of the tuning (80k games) The significant changes are in buckets 1 and 2 (5-12 pieces) so the main difference is in playing endgames if we compare it to nn-33c9. There is also change in bucket 7 (29-32 pieces) but not as substantial as the changes in buckets 1 and 2. If we interpret the changes based on an experiment a few months ago, this new net plays more optimistically during endgames and less optimistically during openings.
