Webb14 juli 2024 · The formula for the SHAP value-based feature importance proposed by Lundberg is specified as an average of the absolute value of each feature’s SHAP value for all instances in the dataset [ 9 ]. However, the conventional SHAP value-based feature importance metric does not reflect the impact of variance in data distribution. Webblets us unify numerous methods that either explicitly or implicitly define feature importance in terms of predictive power. The class of methods is defined as follows. Definition 1. Additive importance measures are methods that assign importance scores ˚ i2R to features i= 1;:::;dand for which there exists a constant ˚
