Re: Leela Nets for Human Training and "Style"

While I can understand not repeating the position in a test suite, I would still include it. The reason is that the openings would be precisely where a player like Fischer would make the most thought out decisions. His predilection for the Ruy, for 1.e4, for the Najdorf are all a part of his style ...

Re: Alpha Zero vs. Leela Zero

If Leela had access to the same number of games for training as Alpha Zero did then would it be as strong as the Alpha Zero on comparable hardware (something that matches 4 tpu)? Leela has had far more in every one of its runs. The current Leela that played and defeated Stockfish in TCEC was traine...

Re: Leela Nets for Human Training and "Style"

One simple and automatic way is thru personality. Example Fischer, collect positions (with some criteria) where Fischer is to move, make it as a test suite where the bm in the epd is Fischer's move in the actual game, then measure the engine's performance by counting how many moves match the bm in ...

Re: SL vs RL

I found my little test MCTS SL program screwing up in game play because this sort of situation..., Black Q gives check. Check piece is en prise. King has some moves. Policy trained SL gave the king move evasions normal probabilities, 0.25, 0.12 sort of values. But the obvious Q capture (which would...

Re: Question for Nelson Hernandez - TCEC power consumption

Question: What is the precise power draw from the A/B machine and the NN machine in the current TCEC 15 Superfinal? We can calculate this value based on hardware specs, but I want to know based on actual measurements, such as with a Kill-A-Watt or similar. Even better, I'd like to see a power use g...

Re: Amd graphic cards for Leela

I've seen Nvidia benchmarks for Leela but not any AMD ones. Are the latest and best amd cards good for Leela? Any benchmarks? The problem is that there is a huge disparity in performance as the Nvidia GPUs benefit from the CUDA coding, while the AMD cards are restricted to the OpenCL model. This ca...

Re: Can Leela use 2x RTX gpus?

No, I am saying it doesn't scale up with more cores at all . In fact, you will lose performance with more cores, not gain. But for the example I gave - dual 2080 Ti - 3 cores is clearly faster than one. I'm not sure I follow your point. Nor do I understand yours. I told the OP that slow clocks were...
