Webb8 okt. 2024 · This package creates SHAP (SHapley Additive exPlanation) visualization plots for ‘XGBoost’ in R. It provides summary plot, dependence plot, interaction plot, and force plot. It relies on the ‘dmlc/xgboost’ package to produce SHAP values. Please refer to ‘slundberg/shap’ for the original implementation of SHAP in Python. Webbshap.values returns a list of three objects from XGBoost or LightGBM model: 1. a dataset (data.table) of SHAP scores. It has the same dimension as the X_train); 2. the ranked variable vector by each variable's mean absolute SHAP value, it ranks the predictors by their importance in the model; and 3. The BIAS, which is like an intercept.
