The standard for visualizing intermediate layer #17

Hi, thank you for providing an excellent toolbox. I have a question for setting the target saliency layer. In the code and evaluation comparison, the saliency layer is set as feature.9 of vgg16 and layer.3 of resnet50.

Why the saliency propagation is stopped at the intermediate layer?

What is the difference between saliency map of feature.1 and feature.9 in vgg network? I saw that the performance of pointing game (Excitation backprop )is decreased when I set the saliency map as feature 1.

Thank you and have a nice day. Nam
