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. WebbShapley, Banzhaf, and chaining interaction indices as well as the M˜obius transform are characterized by imposing additional axioms. Previous to this, we also yield representation theorems for cardinal-probabilistic interaction indices. In order to avoid a heavy notation, we adopt that used in [13].

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. Webb16 sep. 2024 · It can be considered that the interaction index when S is a singleton amounts to the importance index, which leads to two types of interaction indices, one based on the Shapley value and the other based on the Banzhaf index.
