mihifepe, or Model Interpretability via Hierarchical Feature Perturbation, is a library implementing a model-agnostic method that, given a learned model and a hierarchy over features, (i) tests feature groups, in addition to base features, and tries to determine the level of resolution at which important features can be determined, (ii) uses hypothesis testing to rigorously assess the effect of each feature on the model's loss, (iii) employs a hierarchical approach to control the false discovery rate when testing feature groups and individual base features for importance, and (iv) uses hypothesis testing to identify important interactions among features and feature groups.
mihifepe is based on the following paper:
Lee, Kyubin, Akshay Sood, and Mark Craven. 2019. “Understanding Learned Models by Identifying Important Features at the Right Resolution.” In Proceedings of the AAAI Conference on Artificial Intelligence, 33:4155–63. https://doi.org/10.1609/aaai.v33i01.33014155.
