WebbFor 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}. See vignette “Multiple shapviz objects” for how to deal with multiple models or multiclass models. WebbXGBoost is an optimized distributed gradient boosting library designed to be highly efficient, flexible and portable . It implements machine learning algorithms under the Gradient Boosting framework. XGBoost provides a parallel tree boosting (also known as GBDT, GBM) that solve many data science problems in a fast and accurate way.

Webb9 aug. 2024 · To do this we need to “post-process” the SHAP values by adding all the values for one categorical feature together. Unfortunately, there is no straightforward way to do this. We need to manually update the SHAP values object ourselves. We have seen that by using CatBoost we can avoid this process. WebbWhen using the Learning API, xgboost.train expects a train DMatrix, whereas you're feeding it X_train. 使用Learning API时， xgboost.train需要一个火车DMatrix ，而您正在X_train 。 You should be using: 你应该使用： xgb.train(param, train)
