Re: Update Speedy Rating List with the latest NNUE engines

You are correct, Orion's search depth prevents a top rating, but the result is still fantastic, quick and dirty CUTE results, TC=40/20: (...) Also that Orion's time control can be improved, 0.45 is an indication that Orion plays too fast. Wow, Orion at ~3100 elo, that's unbelievable :P *** Stop dre...

It is work now
The problem was I renamed the net, in this case don't work
Excellent ! Yes, I'm sorry but the name of the net is "hardcoded" (the NNUE version remains an experiment).
Anyway, thank you for your interest :)

Re: Update Speedy Rating List with the latest NNUE engines

(...) 1000ms result, this is not normal. (...) +507 (!!) (...) 4000ms (...) NICE 1.2 has been generous to Orion, let's see if CUTE is also. Thanks a lot for testing ! The result seems impressive, in fact. But : 1) according to CCRL and CEGT lists, v0.7 is around +130 elo against v0.6 (I think this ...

Re: Orion 0.7 : NNUE experiment

Don't work on Win 7 64bit and Arena gui :cry: I'm so sorry :( 1) Have you downloaded the network file and put it in the same directory than the binaries ? 2) Several binaries are provided to cope with different CPUs' architectures and sets of instuctions ( en passant , note that only 64-bit CPUs ar...

Re: Orion 0.7 : NNUE experiment

For those who are interested, I have just released the result of my NNUE experiment with Orion : see here . As regards my attempt to build a network trainer, I'm not sure to make progress :) I first thought that I could avoid a premature convergence of the optimisation by setting as primary objectiv...

Re: Update Speedy Rating List with the latest NNUE engines

Hi Ed, I saw your post and decided to provide the result of my NNUE experiments with Orion. If you could add new version (v0.7) and its NNUE declinaison (v0.7.nnue) to your Speedy Rating List, it would be great ! Direct link to Orion v0.7.nnue : here . To make it work, you'll have to download and pu...

Hi Graham,

I saw that Orion v0.7 is now listed on CCRL 40/15 list, and that its gauntlet is finished : a great thank you to all the CCRL team for testing it !

Re: Train a neural network evaluation

(...) The net trained in this way gives a mean error of 200cp that is very high. (...) I have exactly the same here, while trying to implement my own NNUE trainer (see here ) ! As far as I am concerned, I'm using as target the static eval from nn-82215d0fd0df.nnue net and my own dataset, built from...

Re: Orion 0.7 : NNUE experiment

Thx for sharing ! Building a neural network trainer is a lot more complex than implementing NNUE :) First, I reused my PBIL framework, used for v0.6 evaluation tuning. I have no doubt that it works. But, despite several attempts, I didn't manage to obtain a network that produced a satisfying eval (t...
