Pytorch Visual Attribution Methods

A collection of visual attribution methods for model interpretability

Including:

• Vanilla Gradient Saliency
• Grad X Input
• Integrated Gradient
• SmoothGrad
• Deconv
• Guided Backpropagation
• Excitation Backpropagation, Contrastive Excitation Backpropagation
• GradCAM
• PatternNet, PatternLRP
• Real Time Saliency
• Occlusion
• Feedback
• DeepLIFT
• Meaningful Perturbation

Setup

Prerequisities

• Linux
• NVIDIA GPU + CUDA (Current only support running on GPU)
• Python 3.x
• PyTorch version == 0.2.0 (Sorry I haven't tested on newer versions)
• torchvision, skimage, matplotlib

Getting Started

• Clone this repo:

git clone [email protected]:yulongwang12/visual-attribution.git
cd visual-attribution

• Download pretrained weights

cd weights
bash ./download_patterns.sh  # for using PatternNet, PatternLRP
bash ./download_realtime_saliency.sh # for using Real Time Saliency

Note: I convert caffe bvlc_googlenet pretrained models in pytorch format (see googlenet.py and weights/googlenet.pth).

Visual Saliency Comparison

see notebook saliency_comparison.ipynb. If everything works, you will get the above image.

Weakly Supervised Object Localization
