I think I am missing something from your description. In ANN we need to
compute K+1 weight matrices: W1(NxH1), W2(H1xH2), ... WK(HKxM), where N is the
number of inputs (size of feature space), M is the number of outputs, K is the
number of hidden layers, Hi is the size of i-th hidden layer. (Also there are
bias vectors but we can forget about them for the sake of simplicity). Could
you suggest why do you have only two matrices in your description?
