[State Key Laboratory for Novel Software Technology at Nanjing University]

This repo is the official implementation of "Group-CAM: Group Score-Weighted Visual Explanations for Deep Convolutional Networks".

Updates

• 2021/08/18 *

• Adding Grad-CAM, Guided_BP, IG, RISE, Score-CAM and Smooth Grad
• Cluster methods for grouping are supported in Group-CAM
• Adding demo for insertion and deletion

Approach

Figure 1: Pipeline of Group-CAM.

Target layer

ResNet: 'layer4.2', Vgg19: 'features.35'

Demo

To visualize a heatmap, run:

python demo.py --arch vgg19 --target_layer features.35 --input Images/ILSVRC2012_val_00000073.JPEG --output base.png

with insertion and deletion curves:

python demo.py --arch vgg19 --target_layer features.35 --input Images/ILSVRC2012_val_00000073.JPEG --output base.png --ins_del
