Webbtry. These interaction indices extend the Banzhaf and Shapley values when using in addition two equivalent recursive axioms. Lastly, we give an expres-sion of the Banzhaf and Shapley interaction indices in terms of pseudo-Boolean functions.

Webb20 feb. 2024 · Further, we propose a new type of interaction index, i.e., the sum interaction index, and investigate its properties with respect to the additive, subadditive and superadditive monotone measures. Some comparison analyses of the sum interaction index with the Shapley interaction index are also given by several illustrative examples. 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]. inci name witarix mct c8

Webbdefinition to the elementary interaction component and the Shapley-Taylor index among various variables, respectively. These studies quantified the significance of interaction for each possible specific combination of variables, instead of providing a single metric to quantify interactions among all combinations of variables. 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

WebbThe Shapley value of a feature value is the average change in the prediction that the coalition already in the room receives when the feature value joins them. 9.5.3.3 Estimating the Shapley Value All possible coalitions (sets) of feature values have to be evaluated with and without the j-th feature to calculate the exact Shapley value.
