[Computer-go] Fwd: Representing Komi for neural network

2015-03-20 Thread Hugh Perkins
But then, the komi wont really participate in the hierarchical representation we are hoping that the network will build, that I suppose we are hoping is the key to obtaining human-comparable results? Well... it seems that Hinton, in his dropout paper http://arxiv.org/pdf/1207.0580.pdf , get

2015-03-20 Thread Hugh Perkins
Perhaps what we want is a compromise between convnets and fcs though? ie, either take an fc and make it a bit more sparse, and / or take an fc and randomly link sets of weights together??? Maybe something like: each filter consists of eg 16 weights, which are assigned randomly over all
