[Feature Request]: add SHAP analysis / shapley value explanation to machine learning module #2875

Open rd24911 opened 2 months ago

rd24911 commented 2 months ago

Description

thank you for expanding the feature importance function with flexible permutation times in the machine learning module in the latest update! While the permutation-based feature importance is sometimes unstable and without consideration of feature dependence, would it be possible to add SHAP analysis / shapley value explanation to machine learning module?

Purpose

improve the explainability of machine learning models

Describe the solution you would like

add SHAP analysis into machine learning module, either under each of machine learning models or a separate function, and give mean of shapley values of each feature in addition to case-wise explanation
