WebThe Shapley value is defined by an axiomatic approach: it is the unique solution concept that satisfies the efficiency, symmetry, null player, and additivity properties. An explicit formula is provided for the Shapley value of a coalitional game, as a linear function of the worths of the various coalitions. Web5 Nov 2024 · Project description. Shparkley is a PySpark implementation of Shapley values which uses a monte-carlo approximation algorithm. Given a dataset and machine learning model, Shparkley can compute Shapley values for all features for a feature vector. Shparkley also handles training weights and is model-agnostic. shoe store perinton https://poolconsp.com

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.
