WebIntegrated gradients is a simple, yet powerful axiomatic attribution method that requires almost no modification of the original network. It can be used for augmenting accuracy metrics, model debugging and feature or rule extraction. Captum provides a generic implementation of integrated gradients that can be used with any PyTorch model.
