Limitations / Considerations

The project's license is currently unknown, which may affect its use in commercial applications
The complexity of the methods may require a steep learning curve for new users

LIME: A Python package for explaining the predictions of any classifier in a model-agnostic manner, but it is not specific to computer vision tasks.
SHAP: A game theoretic approach to explain the output of any machine learning model, also not limited to computer vision.
Captum: A PyTorch library for model interpretability, which offers a range of methods but may not be as specialized in computer vision as pytorch-grad-cam.
