Webb25 nov. 2024 · The SHAP library in Python has inbuilt functions to use Shapley values for interpreting machine learning models. It has optimized functions for interpreting tree-based models and a model agnostic explainer function for interpreting any black-box model for which the predictions are known. In the model agnostic explainer, SHAP leverages …
