Explainable AI for Medical Images

This repository shows an example of how to use MATLAB to produce post-hoc explanations (using Grad-CAM and image LIME) for a medical image classification task.

Both methods (gradCAM and imageLIME) are available as part of the MATLAB Deep Learning toolbox and require only a single line of code to be applied to results of predictions made by a deep neural network (plus a few lines of code to display the results as a colormap overlaid on the actual images).

Example of gradCAM results.
Example of imageLIME results.

Experiment objective

Given a chest x-ray (CXR), our solution should classify it into Posteroanterior (PA) or Lateral (L) view.

Dataset

A small subset of the PadChest dataset1.

Requirements

Suggested steps

  1. Download or clone the repository.
  2. Open MATLAB.
  3. Edit the contents of the dataFolder variable in the xai_medical.mlx file to reflect the path to your selected dataset.
  4. Run the xai_medical.mlx script and inspect results.

Additional remarks

  • You are encouraged to expand and adapt the example to your needs.
  • The choice of pretrained network and hyperparameters (learning rate, mini-batch size, number of epochs, etc.) is merely illustrative.
  • You are encouraged to (use Experiment Manager app to) tweak those choices and find a better solution.

Notes

[1] This example uses a small subset of images to make it easier to get started without having to worry about large downloads and long training times.
