Re: Yet another parameter tuner using optuna framework

Those are the bishops. Now if we look at the slice plot, the tuner is somewhat confused, the trials are all over the place for the BishopValueEn. Trials are somewhat divided in the 320 to 340 range and also in the 340 to 360 range. The number of trials for those plots are 300 from 24 games/trial at...

Hi Jörg

Thanks a lot for this tunable Stockfish. If possible can you also put NNUE inside, ( whitout) embeeded net :) :)
For what purpose?
If you simply want a configurable Stockfish, for the handcrafted eval that is,
there are some forks around which offer this functionality.

Re: Yet another parameter tuner using optuna framework

@Joerg Could you create a Stockfish where it exposes its material piece value and other evaluation param perhaps and a couple of search parameters. I can make it but may take sometime. I want to test optuna with it and later compare with other tuner like spsa and chess tuning tools and others perha...

Sorry everyone. My problem is not solved but no problem. As some members pointed out, I maybe doing somethi...

Re: Yet another parameter tuner using optuna framework

3. I'm not sure if parameter changes to a 'quick match' change all five parameters at a time, or just one? Sorry I don't understand the question. I guess he wants to know if the tuner changes all parameters at once or one by one for a new trial. In the document they refer to this as relational samp...

Re: Yet another parameter tuner using optuna framework

Thanks Ferdy for making your tool available! I like some of the plots you output for the results. I wanted to point out that Optuna uses tree-structured parzen estimators as their model, which does not model interactions between parameters. Tools based on Gaussian processes (like the chess-tuning-t...
