Webb2 mars 2024 · Shapley interaction indices extend the Shapley value to define any-order feature interaction scores. Defining a unique Shapley interaction index is an open research question and, so far, three definitions have been proposed, which differ by their choice of axioms. Moreover, each definition requires a specific approximation technique. Webb9.2.4 Shapley Value and Interaction Index Shapley value measures the overall importance of each criteria in terms of its contribution to the score of each group of criteria.

In game theory, Grabisch and Roubens [11], Lundberg et al. [16] proposed and used the Shapley interaction index based on Shapley values [22]. Sorokina et al. [26] proposed an approach to detect interactions of input variables in an additive model.
