WebbXGBoost LightGBM h2o kernelshap fastshap shapr treeshap DALEX For XGBoost, LightGBM, and H2O, the SHAP values are directly calculated from the fitted model. CatBoost is not included, but see Section “Any other package” how to use its SHAP calculation backend with {shapviz}. 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. onslowarmsclandon.co.uk
