Matconvnet output of deep network's marix is uniform valued instead of varying values?
问题 Im trying to achieve a density map from network output of dimension 20x20x1x50. Here 20x20 is the output map and 50 is the batch size. The issue is that the value of output X is equal 0.098 across each output matrix..20x20. There is no gaussian shape like density map but a flat similar valued output map 20x20x1x50. The issue is shown in the figure attached. What am i missing here? The euclidean loss for backpropagation is given as: case {'l2loss'} res=(c-X); n=1; if isempty(dzdy) %forward Y =
