Accurate estimation of feature importance faithfulness for tree models

no code implementations4 Apr 2024 Mateusz Gajewski, Adam Karczmarz, Mateusz Rapicki, Piotr Sankowski

In this paper, we consider a perturbation-based metric of predictive faithfulness of feature rankings (or attributions) that we call PGI squared.

Improved Feature Importance Computations for Tree Models: Shapley vs. Banzhaf

no code implementations9 Aug 2021 Adam Karczmarz, Anish Mukherjee, Piotr Sankowski, Piotr Wygocki

Using the computational techniques developed for Shapley values we deliver an optimal $O(TL+n)$ time algorithm for computing Banzhaf values based explanations.
