Re: Pytorch NNUE training

An initial training run by vondele on 256M positions is looking much more promising (also takes about 10 minutes to do an epoch - a pass through the 256M positions, which is great). Getting closer! Note that all training runs so far have been with lambda = 1.0 (train to the evaluation, not the game...

Re: Final Release of Ethereal, V12.75

You can see what Andrew's done on Halogen on my GitHub repo. Andrew's current interest now he isn't working on Ethereal is working on a NN trainer and may very well have a trainer that is better than the one that SF uses to train its NNUE nets. He sometimes trains Halogen networks to test the train...

Re: Future of computer chess: 2 top engines?

Madeleine or whatever is your right name. Explain me ... What is your interest on computer chess! At the moment I can't understand a lot of your messages! In this thread specifically I speculated earlier that if other engines such as Komodo adopted NNUE they may gain a strong enough positional judg...

Re: Pytorch NNUE training

Interesting! One of the experiments I had lined up was disabling the factorizer on the nodchip trainer and seeing how it did. But I’ll take your word for it :). I had already started implementing it, there are some really cool tricks the Shogi folks pulled off - zeroing the initial weights for the ...

Re: Pytorch NNUE training

The adventure continues! So far, I've managed to validate that we can import a quantized SF NNUE net into the pytorch float32 representation, and export it back without any loss (even the same sha for the nnue net). So the quantization/dequantization code looks solid. That's done with https://githu...

Re: A new website for Shredder ...

"Most successful chess program ever". Yeah, that would be Stockfish. Money pushes them to deceive. They ask for 50$ more to get access to the multi-threaded version of Shredder 13. This is a borderline scam, SMP has been a standard feature for many years and is present in the 8-10 free engines stro...

Re: Final Release of Ethereal, V12.75

Mike, I felt that he was evolving in a known paradigm, chasing SF -- similar approach, similar methodology, and, to be honest, I thought it was in part a waste of talent (learning aside). Now, he is on his own path, and with his energy I am sure results could come fast. Anyway, I hope he will conti...

Both Halogen and Seer are comparatively all original. Both just happen to rely on the "efficiently updatable" idea. They probably shouldn't be lumped into the same category as Komodo+NNUE.
+1, Agreed.
