Web22 Feb 2024 · 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. The Shapley value is provably the only solution concept satisfying these axioms. In this paper, we introduce the Shapley value … WebBesides efficiency, the Shapley values uniquely satisfy three other desirable properties [27]. Linearity: for two value functions v 1 and v 2, we have ˚ i( 1v 1 + 2v 2) = 1˚ i(v 1) + 2˚ i(v 2). This guarantees that the Shapley value of a linear ensemble of models is a linear combination of the individual models’ Shapley values.
