Hi,
Nice code! For the sake of completeness, I think it would be great to add
Simple feature map visualization
CAM only (no grad) through "Learning Deep Features for Discriminative Localization" (http://cnnlocalization.csail.mit.edu/)
(I think Grad-CAM is this ref "Grad-CAM: Visual Explanations from Deep Networks via Gradient-based Localization" not the previous one)
