Shapley value sampling
Webb20 nov. 2024 · What is SHAP. As stated by the author on the Github page — “SHAP (SHapley Additive exPlanations) is a game-theoretic approach to explain the output of any machine learning model. It connects optimal credit allocation with local explanations using the classic Shapley values from game theory and their related extensions”. Webbclassification trees and SHapley Additive exPlanations (SHAP) analysis to explore the errors in the prediction of lightning occurrence in the NASA GEOS model, ... these techniques calculate SHAP values through sampling the predictions of a given model by replacing some model input values with random values from that input distribution.
