Re: Fireworks for the Fourth

It's Independence Day in the US, so to celebrate the holiday I'm sharing some recent CyberNezh brilliancies, full of dazzling sacs and daring attacking play, drawing the opponents into a dubious-but-deadly morass of complications.

Re: Leela Nets for Human Training and "Style"

I have tried combining 4 features in the regression instead of 1 feature at a time, so we can get feature coefficients simultaneously. Will try to post this later. Would be interesting to discover their weights and compare it to the weight which was done individually. Sample run with 4 independent ...

Re: Leela Nets for Human Training and "Style"

can you send Mg, Eg for both sides to the model? eg four variables. Could be that a GM is asymmetric Some test result without norm to [0,1], also added the 4 variables on mobility, i.e WMobilityMgCP, WMobilityEgCP, BMobilityMgCP, BMobilityEgCP. Regression summary results when each feature has a val...

Re: Leela Nets for Human Training and "Style"

This is very cool. Have you considered running through 2 chess engines's games on there and take a look at their numbers? Human players are playing distinctively, I wonder if chess engines would look alike because they'd play the same moves on the same situations. Otherwise, some engine could be fo...

Re: Leela Nets for Human Training and "Style"

Nice. Okay, so as I understand this ... Player is white, positions are white to move, game result is a white win, evals are normalised 0-1? Yes Clarifying questions ... where do you get the feature evaluation from? the root or the final move in the PV? Root, as I am using eval command of Stockfish....

Re: Leela Nets for Human Training and "Style"

Different approach, but involves a bit of chess programming.... Build evaluation feature list. mobility for each piece, pieces hanging, pieces attacked, attacks around king, something about pawns, castle status, each piece development, checks, and so on, use your imagination. Sure we can do that. P...
