Networks for lc0

I got fascinated, but also admitdly lost, with all the recent development on programs able to use neural networks for playing. Is there any resource that would summarize how to build those networks? Also, as I don't have a GPU on my computer, would your recommend any small network to play with on lc0 or similar software?
Thanks in advance.

The LC0 site has instructions on how to participate in network building.
If you want to experiment with LC0, buy yourself an inexpensive GPU. Here is a listing by price performance:

Thanks, Dann. If you don't mind, have another question. Do you think that it would be feasible to feed to lc0 games of a given player to come up with an evaluation function that somehow reproduces his/her style? I know that some programs try to imitate the personality of some players (like PlayMagnus), but I am not so sure that this is the algorithm they use.
Thanks again.

I’ve championed the cause of running lc0 on weak hardware, like integrated gpu, cpu, or even Android. It is possible to get that style of play on very modest hardware.
The best small net (128x10 as opposed to 256x20 or larger) is LD2. It gets very decent performance on cpu as long as you aren’t playing ultra-bullet.

There are also a number of smaller nets distilled from ID 11258.

There are a number of other small nets, but I’d mention Mean Girl, a tiny 32x4 net. It plays on lichess looking at 25 nodes on a raspberry pi 3.

Yes, if you have a collection of 1, 000,000 games of a player.
e.g, You want to learn NN this is a cat, you need to show a million pictures of cats.
Btw, a guy in lichess has played 0.35 million games. He might be the first human in history who played > 1 million record.

Are you sure this "guy" is not a bot?

20 years ago FICS has some blokes with over 200k games ... if you have an account there, you can try fingering some of the prolific names I remember:
theblob, obliviax, andred

I love your work.
Any estimation of Mean Girl's (32x4) 25 node ELO? 2500 Rapid ELO seems hard to believe.
