Shapley values for feature selection: The good, the bad, and the axioms

no code implementations22 Feb 2021 Daniel Fryer, Inga Strümke, Hien Nguyen

The Shapley value has become popular in the Explainable AI (XAI) literature, thanks, to a large extent, to a solid theoretical foundation, including four "favourable and fair" axioms for attribution in transferable utility games.

We state theoretical properties for $k$-means clustering of Symmetric Positive Definite (SPD) matrices, in a non-Euclidean space, that provides a natural and favourable representation of these data.
