Scaling SHAP Calculations With PySpark and Pandas UDF

WebbOne line of code creates a “shapviz” object. It contains SHAP values and feature values for the set of observations we are interested in. Note again that X is solely used as explanation dataset, not for calculating SHAP values. In this example we construct the “shapviz” object directly from the fitted XGBoost model. Webb3 nov. 2024 · The SHAP package contains several algorithms that, when given a sample and model, derive the SHAP value for each of the model’s input features.
