It is one of the few … Webb18 juli 2024 · It is possible to do this by passing a function handle to shapley.This function handle needs to output the score for the class of interest. Also, shapley expects inputs and outputs for the function handle to be row vectors rather than column vectors, so some transposes are needed. Below is an example using the Fisher Iris data:

Webb26 nov. 2024 · It provides three main “explainer” classes — TreeExplainer, DeepExplainer and KernelExplainer. The first two are specialized for computing Shapley values for tree … Webb16 juli 2008 · This paper presents the first general results on weighted Shapley network design games. First, we give a simple example with no pure-strategy Nash equilibrium. This motivates considering the price of stability with respect to α -approximate Nash equilibria—outcomes from which no player can decrease its cost by more than an α … dapsone topical directions
