Shapley Values for Feature Selection: The Good, the Bad, and the Axioms
IEEE Access, 2021 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.

Model independent feature attributions: Shapley values that uncover non-linear dependencies [PDF]
PeerJ Computer Science, 2021 Shapley values have become increasingly popular in the machine learning literature, thanks to their attractive axiomatisation, flexibility, and uniqueness in satisfying certain notions of ‘fairness’. The flexibility arises from the myriad potential forms

VMD-WSLSTM Load Prediction Model Based on Shapley Values
Energies, 2022 Accurate short-term load forecasting can ensure the safe operation of the grid. Decomposing load data into smooth components by decomposition algorithms is a common approach to address data volatility. However, each component of the decomposition must be

GPUTreeShap: massively parallel exact calculation of SHAP scores for tree ensembles [PDF]
PeerJ Computer Science, 2022 SHapley Additive exPlanation (SHAP) values (Lundberg & Lee, 2017) provide a game theoretic interpretation of the predictions of machine learning models based on Shapley values (Shapley, 1953).

Shapley Values as a Strategy for Ensemble Weights Estimation
Applied Sciences, 2023 This study introduces a novel performance-based weighting scheme for ensemble learning using the Shapley value. The weighting uses the reciprocal of binary cross-entropy as a base learner’s performance metric and estimates its Shapley value to measure ...

On weighted Shapley values [PDF]
International Journal of Game Theory, 1987 Nonsymmetric Shapley values for coalitional form games with transferable utility are studied. The nonsymmetries are modeled through nonsymmetric weight systems defined on the players of the games. It is shown axiomatically that two families of solutions of this type are possible.

Some Properties of Interval Shapley Values: An Axiomatic Analysis
Games, 2023 Interval games are an extension of cooperative coalitional games, in which players are assumed to face payoff uncertainty. Characteristic functions thus assign a closed interval instead of a real number.
