We ran a test match and ELFv2 lost 34 - 62 against LZ-204 at 1600 visits
each, so that's about +100 Elo in favor of LZ at visits rather than time
parity.

This would mean going 800p -> 400p gives -200 Elo? Seems more than I
would expect.

I think I'd want to do more testing before forming an opinion :-)

Smaller networks have more overhead (heads etc are fixed), so it's
closer to ~60%. Probably depends on the GPU too.

Hi Ingo,


* How strong is the new ELF bot in comparison with Leela-Zero?


from CGOS BayesElo, new ELF(ELFv2) is about +100 stronger than Leela-Zero.

Rating  Network size(Resnet layers x filters)
LZ_05db_ELFv2_p800  355420x256
LZ_d13c_ELFv1_p800  353020x224   second release ELF
LZ_62b541_ELF_p800  350020x224   first release ELF
LZ_204_05d1_p400343340x256   latest(2019-02-13) LZ

p800 means 800 playout/move.
p400 means 800 playout/move.
Leela Zero's playout is half. Because its net size is double.

Re: [Computer-go] A new ELF OpenGo bot and analysis of historical Go games

2019-02-17 Thread Stephan K
"The sudden overall increase in agreement in 2016 also reinforces the
belief that the introduction of powerful AI opponents has boosted the
skills of professional players. That apparent correlation isn't
conclusive — it's possible that humans have gotten markedly better for
some other reason — but it's an example of how a system trained to
carry out a given task can also provide wide-ranging analysis of a
larger domain, both in the present and from a historical perspective.
"

They are using their go AI to measure the strength of human go
players, and use its analysis to 'prove' that copying the moves of AIs
has made humans stronger (or at least, quantify this increase in
strength).

There is a huge bias there. I think this is like asking a fisherman
whether chefs who specialize in fish have better cooking skills than
chefs who specialize in meat...
