WebJul 20, 2024 · First you need to verify that your data is valid since you use your own dataset. You could do this by visualizing the minibatches (set the cfg.MODEL.VIS_MINIBATCH to True) which stores the training batches to /tmp/output. You might have some outlier data that cause the losses to spike. Set your learning rate to something very very low and see ... 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.
