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

Hi Aja, I hope you enjoy our work. Comments and questions are welcome. I have three questions. I don't understand minibatch. Does CNN need 0.15sec for a positon, or 0.15sec for 128 positions? ABCDEFGHJ 9. White(O) to move. 8...OO Previous Black move is H5(X) 7..XXXOO.. 6

Hi Aja, We've just submitted our paper to ICLR. We made the draft available at http://www.cs.toronto.edu/~cmaddis/pubs/deepgo.pdf 97.2% against GNU Go?! Accuracy is 55%?! Incredible! Thanks for the paper! But it looks playing strength is similar to Clark's CNN. MCTS with CNN is interesting. B
