Shapley interaction index
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. WebbUsing the Shapley value and the Interaction Index, the insight into the preferences of customers, along with interaction among criteria, can be explored. • To introduce a new toolbox, the Rfmtool package, for customer preferences …

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 … Webb1 jan. 2024 · A Shapley-Owen Index for Interaction Quantification Semantic Scholar The recent work of Owen has introduced the Shapley value as an importance measure for global sensitivity analysis (Shapley effect) in Uncertainty Quantification.

Two of them are proposed: at first a recursive axiom is used by extension of the one of Grabisch and Roubens [10], and subsequently we work out the reduced-partnership- consistency axiom using the concept of partnership [5]. 2.
WebbBART models and compute Sobol index and Shapley e ect estimates is found in [46]. Regarding computation, it is challenging to encode an arbitrary (e.g. nonorthogonal) input design with full support into a BART model. This can be possibly achieved by replacing the volume of each hyperrectangle used to compute BART-based Sobol indices and Shapley
