Re: Trying out the Leela Hybrid engine (NN with AB)

I think it's important to keep in mind that we assume Auxiliary engine must just help Lc0 tactically, and ideally it's much weaker than both Lc0 and its opponent. Many might be be tempted to use Auxiliary engine the level of SF, while their Lc0 is weaker than SF in some conditions. Even on my power...

Re: Trying out the Leela Hybrid engine (NN with AB)

do you mean lower ST (if you're referring to the threshold value)?

Re: Trying out the Leela Hybrid engine (NN with AB)

even w/ GTX 1080 i'm seeing +50 elo at 1+1, with a sample size caveat. T40 outperformed 32930 over 50 games (+35 elo), -70 elo to SFdev (4 cores @ 4.4ghz). same T40 network was -135 to SFDEV & -30 to 32930 (only 25 games each). using 3 threads for SFdev as aux engine, 1024MB hash, everything else de...

Re: LCZero Network question

i think 35xx+ were precursor training for t40. it was fully trained (all 4 LR drops) & in some way used to initialize T40 training. it should be much better on CPU than 256x20 nets since it's both mature & fast. t50 i don't know anything about; it's got some new parameters & uses 10000 visits instea...

Re: TCEC 14 final: Lc0 just lost 3 games with tactical..

fwiw, i find t40 passing all of these (these being the 3 starkest blunders i've found so far) & avoiding a couple other, less-losing moves i've tested, but have only analyzed the Kf1 blunder at several MNs. 1r1q1rk1/p1pbbp2/7p/8/2PPnP2/1P6/PB2B2p/RN1Q1R1K w - - 0 20 31 [bm Qd3 (??)] 20.

Re: TCEC 14 final: Lc0 just lost 3 games with tactical..

NNs use is & imo will be in revealing long-term plans & concepts; there's simply no way any conceivable-at-present NN can be completely trusted in a thorough analysis without AB-search double-checking it.

Re: TCEC 14 final: Lc0 just lost 3 games with tactical..

i'm not sure that's true, but i haven't seen 2 of them. i do know that t40 avoids the Kf1 blunder (tested id40743) after around ~200KNs, but i don't know how long it takes to find Bxf2+ after Kf1 with clean search: [d]6k1/b3q3/Q3b2p/p2p1p2/4n3/3B1N2/PP3PPP/2rNR1K1 w - - 6 34 when i checked, SFs repl...

Re: Lc0 with latest test30 nets is vastly superior positionally

Yes I still don't understand why Lc0 can play so incredibly strong and yet fall for 1 move tactical blunders. Fortunately that happens quite rarely, but I think that is something that should and will probably be fixed very soon. I mean to be able to see a shallow tactic that is only 3 ply deep cann...
