Webb4 jan. 2024 · Indeed, SHAP is about local interpretability of a predictive model. A power set of features. By way of example, we will imagine a machine learning model (let’s say a linear regression, but it could be any other machine learning algorithm) that predicts the income of a person knowing age, gender and job of the person.

Webb12 feb. 2024 · This post will dive into the ideas of a popular technique published in the last few years call SHapely Additive exPlanations (or SHAP). It builds upon previous work in this area by providing a unified framework to think about explanation models as well as a new technique with this framework that uses Shapely values. Webb2 maj 2024 · Herein, we evaluate a recent methodological variant for exact calculation of Shapley values using tree-based methods and present new applications of the SHAP approach including interpretation of DNN models for the generation of multi-target activity profiles of compounds and regression models for potency prediction.
