It is not running on my w10 build 19042.906 (latest) and even on previous build.

Thanks for sharing. Do you have info what options were used to generate these bins? What stockfish version? I've been keep a record and will add the gensfens options sometime soon. Switched to a new configuration that is supposed to be base on the what the current best nnue nets have used as input....

As we all know, the classic evaluation functions are a tradeoff between speed and accuracy but given that most NNUE nets are trained using fixed depth search results, speed would no longer be a factor. I was wondering if much more complex/accurate evaluation functions would result in stronger nets....

If anyone is looking for a source of binpacks, I've been building and releasing them on one of my sites for download.

What is a binpack, exactly?

A format for training and validation files.

I am aware of the random move options. Actually as I have posted before, the way gensfen does this seems to me unsound, because it will score the whole game with the ultimate result, even though a random move inserted in the middle can change the eval significantly, and so really then the previous ...

Hi. During the last couple of days I've been struggling with writing a working king safety evaluation. Every time I try to test it against the oldest version of my engine it seems to either loose 30-60 elo or only gain a negligible 5-10 elo (as compared to the results of others's implementations th...

I have a database of chess games in PGN format. My goal is to index them into a representation that I can search for similarity. For example, let's say I have 2 games in King's Indian and 1 game in Queen's Gambit Declined. Now, I have a new Queen's Gambit Accepted chess PGN game. The closest in the...

I am doing some experiments with https://github.com/bmdanielsson/nnue-trainer and have a couple of questions: 1. What's a typical number of positions for training and validation? 2. I am seeing that the objective values seem to go down with increasing training set size. For example, 5 million posit...
