Yes, it's 0.15 seconds for 128 positions. A minibatch is a small set of samples that is used to compute an approximation to the gradient before you take a step of gradient descent. I think it's not simply called a "batch" because "batch training" refers to computing the full gradient with all the

Is "KGS rank" set 9 dan when it plays against Fuego? For me, the improvement from just using a subset of the training data was one of the most surprising results. As far as I can tell, they use ALL the training data. That's the point. They filter by dan, and the CNN must then have less confide

Follow up question to the testing, how should I interpret the resulting html file from the analyze command? I alternate colors between the engines, Gnu Go is Black in the first game. Both Gnu Go and my engine have a section in the html file with Black Wins x%. Is that the amount of wins for eac
