Re: FGRL - 16 Cores rating list - 2. Fat Fritz 1.1

Leelenstein is defending its title, and in the lead at WCEC https://www.twitch.tv/navratil25 Its 2 RTX gpus with a strong I9. Leela ratio is a little worse than last TCEC season. If he disabled a few threads from SF it matched TCEC's ratio, but this tournament is at full bore. You can see a lot more...

Re: 1.g4 opening is losing?

I debated over using q output that goes from -100 to 100 but decided to use winrate percentage that goes from 0 to 100 instead, since I think it's just a little bit more clear - and the CP output doesn't really mean anything with every engine using a different formula and it being so far removed fro...

Re: 1.g4 opening is losing?

The threshold for a won position is probably about 70% or perhaps slightly higher, 71 or 72%, based on everything I've observed. For 1 g4?, it is about 68% for Black with 1...d5, so probably not a forced win although close enough to the line to leave that as a possibility. Leelenstein 13 already is...

Re: FGRL - 16 Cores rating list - 2. Fat Fritz 1.1

Using the kiudee settings Pohl used? WCEC is using these similar settings: "Threads": 3, "MinibatchSize": 512, "Cpuct": 1.9000 "NNCacheSize": 20000000, "maxCollisionEvents": 32 "CPuctBase": 15000, "CPuctFactor": 2.817, "TradePenalty": 0.0 "TradePenalty2": 0.0 "TempDecayMoves": 0, "TempCutoffMove": 2...

NN-testrun of Lc0 0.23.3k Leelenstein 14 finished - a fantastic result! Massive progress to Leelenstein 13 (+46 Elo) and the clear world's number 1. Congrats to Jjosh - great job.

Re: Can Leela CPU train from a PGN file instead of selfplay?

I'm hoping that it's possible for Leela CPU to train from a large PGN file instead of selfplay. If so, does anyone know how to explain it simply enough for an average Joe to understand it? There are many different levels to do this. If you just use straight PGN it creates a very weak policy head (l...

Re: Can Leela CPU train from a PGN file instead of selfplay?

I wonder what would happen if the entire Lichess database was used to train a neural network. It wouldn't play very strongly but could possibly play in a way indistinguishable from humans. That is what the Darkqueen net is actually. Although latest ones have added a little bit of other data as well.
