Re: NNUE nets with depth of 20?

I always saw that there are 12 or 8 depth that is been used
Remains to be proven in a meaningful way that some depth is better than another depth.
I believe Boujin tried d20 networks, with very little success.

Re: HalfKP Structure in NNUE

Apologies for cross-posting on different sites. I've already posted this question on chess.stackexchange, but it seems it does not reach the proper audience there (few views, no replies despite bounty). I took a stab at answering each of your questions: https://chess.stackexchange.com/questions/336...

Re: Komodo Dragon is Kicking Ass in TCEC

Good thing I am not in charge, as your ass would be banned purely on stupidity! Are you always this chippy? Actually, no! However, the statement fits the one it addressed, even if a bit to harsh. Hey Robert. I have a mailing list for people who like to trash talk Dkappe. Reach out if you want to be...

Re: Help with Texel's tuning

Depending on your mathematical education, you can read https://github.com/AndyGrant/Ethereal/blob/master/Tuning.pdf. I recommend atleast some basic knowledge about multivariate calculus. Then it is easy. For more questions on the contents of this, you can also ask Andrew directly I suppose or me he...

The code snippets are not a great source of utility, but the words behind them layout a framework for anyone to follow. ...

Re: The Next very strong Engine will be rofChade NNUE

you really must work on the way you use the forums. Quoting yourself means I just skip the post, since I assume I've already read it. Plus you can delete part of the quote history that is not revelent. Otherwise in a long enough forum, the quote takes up an entire page per posting.
