Re: Lozza 2.0

Re: NN. I suspect one can in-line assembly code into Node.js and possibly browsers, but then one is drifting away from the whole point of using Javascript in the first place I guess. I wrote the neural network training code in JavaScript as well. I did not use any other language. It's slow, but wor...

Cheers Tamás; tuning was pretty interesting. But if I had known about NNUE when I started maybe I would have skipped it :)
I haven't dropped the old tuned evaluation yet.
Maybe I won't. Even so, my Neural Network works.
Unfortunately, I have little time to experiment further now.

Re: Lozza 2.0

Thanks, Colin. How do I download it? Hi Graham, long time no speak. In the repo you can click on the green "code" button to download everything (it's not very big) - unzip and grab lozza.js. Or click on lozza.js in the repo (link below) and copy-paste into a local file of the same name. https://git...

Re: tomitankChess 5.0 with NN

I increased the hash size to 512MB!
Please download the latest release again :)
it's called still 5.0, because I don't want to send 1 more version to the rating lists.
There is probably not much difference, but i would be happy when all tester use the updated version for remaing tests.

Re: 256 in NNUE?

https://www.chessprogramming.org/Stockfish_NNUE. In the NNUE network architecture, I can see 256 weights in the first hidden layer. It requires an int16 to keep the weights. Can we reduce the number of hidden layer neurons from say 256 to 128, and it will reduce the size of the weights to int8? Als...

Re: tomitankChess 5.0 with NN

Hello Tamás, This looks awesome. That level of strength with so few lines of code in JavaScript is impressive. Unfortunately, I can't get it to work with node 15.7 under macOS. I tried running the engine with "node tomitankChess.js" and then typing "uci". It then prints what looks like normal UCI i...

Hi, Can you change the hash? And if yes, how ? It does not exceed approx. 350 M. in Arena (I have set the hash for all engines to 2048 M)
Hi,
256 MB is the maximum value now.
In the next version, it will increase to 1GB.

McBrain JS has nothing to do with Javascript. It means that the EXE was compiled by John Stanback.

Re: stockfish NNUE question

What is the function of Features::Side::kFriend? This is defined as: enum class Side { kFriend // side to move }; and it is used as template parameter. But isn't this just a constant, since Side has only one value defined? How is it the "side to move?" --Jon Hi! I know this is not the answer to you...
