Demo GradCAM & Guided GradCAM

Open In Colab

On Dogs vs. Cat data

Architecture: ResNet50 & ResNet50 + FC layers

An interactive demo for GradCAM and Guided GradCAM, implemented with Tensorflow 2.x

Detailed analysis and training notebook: https://www.kaggle.com/nguyenhoa/dog-cat-classifier-gradcam-with-tensorflow-2-0

Prerequisite

  • Python 3.6
  • Required packages
bash requirements.txt

Demo

You can run on your own resources with the file Visualization.ipynb

Otherwise, you can run on Google Colab easily via this link: https://colab.research.google.com/github/nguyenhoa93/GradCAM_and_GuidedGradCAM_tf2/blob/master/Visualization.ipynb (Don't forget to change your runtim to Python3 and choose GPU as your hardware accelerator.)

  • Model: There are two trained models, which are
    • VanilaResNet50: Keep the same architecture of ResNet50, replace the output layer on ImageNet and re-train with Dog vs. Cat data.
    • ResNet50PlusFC: Add 2 fully connected layers between Average Pooling layer and output layer and train on Dog vs. Cat data.
  • Image: There are some available sample images in assets/samples, if you want to run your own ones, put them in this folder to be displayed on the dropdown list.
  • Class: This will be the class for GradCAM and Guided GradCAM visualization.
