32930 Boost network available

Post by dkappe »

https://github.com/dkappe/leela-chess-w ... t-Networks

Based on my hypothesis on what was the critical element in the success of Antifish, this is 32930 sharpened with CCRL games at a low learning rate and a very few steps. Seems to give around 30 elo extra than the original net. I'll be doing this for a T40 net as well.

Very good idea! Thanks for share!
I am testing Lc0 Boost 32930, Lc0_32930 and Lc0_41871, all with 0.21.1, on Rtx2070 against Stockfish dev. i7 4790S 8 cores

I don't think that this test can talk about anything. Need more games:

Code: Select all

# PLAYER              :  RATING  ERROR  POINTS  PLAYED   (%)  CFS(%)    W    D    L  D(%)
1 32930-boost-1000    :       0     30    33.5      60  55.8      77   12   43    5  71.7
2 32930               :     -25     49    14.0      30  46.7      78    3   22    5  73.3
3 11258               :     -62     50    12.5      30  41.7     ---    2   21    7  70.0

White advantage = 78.53 +/- 24.80
Draw rate (equal opponents) = 82.20 % +/- 7.64
5-3 is not 30 Elo. It is unknown.

I applied this to my own 256x20-se net called Maddex and ran 2+2 for 800 games and got +30 elo. Right now I’m running tests for 500 to 4500 step nets. 32930 may need more steps. TBD.

Test with Silver suite 50x2 game each match:
Lc0 Boost 32930, Lc0_32930 and Lc0_41871, all with 0.21.1 version, on Rtx2070 against Stockfish dev. i7 4790S at 3.6 MGhz. 8 cores at 5 minutes plus 3 seconds under Fritz gui. First half of the test finished with 150 games played.

Lc0 Boost 32930 scored much better than 32930 and almost as good as 41871.

Would it be possible to distill the latest network to 16x2?

I assume you need an Nvidia GPU for it. (Which I don't have)

Stockfish 090419 64 BMI2 - Lc0 v0.21.1_32930 25.0 - 25.0 +7/=36/-7 50.00%

so that the total test result is

Stockfish 090419 64 BMI2 - Lc0 v0.21.1_41871 46.5 - 53.5 +10/=73/-17 46.50%

Stockfish 090419 64 BMI2 - Lc0 v0.21.1_32930 51.5 - 48.5 +16/=71/-13 51.50%

and Lc0 with 32930 Boost gets the best result!

Which T40 net do you think you'll choose ?

The distillation process doesn't work on test 40 and above networks, yet.
Judge without bias, or don't judge at all...

After some additional testing, the boost net at 7000 steps is about the same head 2 head and vs sf10 at 1+1. The style of play is a bit different, however. Would appreciate feedback. https://github.com/dkappe/leela-chess-w ... t-Networks
