Captum is an open-source, extensible PyTorch library for model interpretability, supporting multi-modal models and facilitating research in interpretability algorithms.
Captum is an open-source model interpretability library for PyTorch. It provides tools to understand and attribute the predictions of PyTorch models across various modalities like vision and text. Built directly on PyTorch, Captum supports most PyTorch model types and integrates with them with minimal modification. It is designed to be extensible, allowing researchers and developers to easily implement and benchmark new interpretability algorithms. Captum offers a generic framework for attributing the importance of inputs, features, or layers to the output of a neural network. It is intended for use by machine learning practitioners and researchers who want to gain insights into their model's behavior and improve its transparency.

Calculates the integral of the gradients of the model's output with respect to the input features along a path from a baseline input to the actual input. Provides a smooth approximation of feature importance.
Computes the gradient of the model's output with respect to the input features at the input point. Highlights the regions of the input that most influence the model's prediction.
Attributes the contribution of each layer in the neural network to the final output. Useful for understanding which layers are most important for a specific prediction.
Attributes the contribution of individual neurons to the final output. Allows for fine-grained analysis of which neurons are most influential.
Compares the activations of each neuron to its 'reference activation' and assigns contribution scores based on the differences. Handles non-linearities better than simple gradients.
