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 git@github.com: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

TBD
