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.

WebbInteractions between input variables of deep models have been widely investigated in recent years. 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. Webb14 feb. 2024 · We propose a new interaction index called Shapley-Taylor interaction index. It decomposes the value of the game into terms that model the interactions between subsets of players, analogous to how the Taylor series represents a function in terms of its derivatives of various orders. We axiomatize the method using the standard Shapley …

WebbHowever, extending the Shapley value to assigning attributions to interactions rather than individual players, an interaction index, is non-trivial: as the natural set of axioms for the original Shapley values, extended to the context of interactions, no longer specify a unique interaction index.
