I was finally able to convert a numpy matrix, given in depth, row, col, format to a single sheet of column vectors (per image). In MATLAB I would have done something like: output = reshape(imStack,[row*col,depth]) In Python this seems to translate to: import numpy as np output=...
% Obtain Theta1 and Theta2 back from nn_params Theta1 = reshape(nn_params(1:hidden_layer_size * (input_layer_size + 1)), hidden_layer_size, (input_layer_size + 1)); Theta2 = reshape(nn_params((1 + (hidden_layer_size * (input_layer_size + 1))):end), num_labels, (hidden_...
