WebbThese plots require a “shapviz” object, which is built from two things only: Optionally, a baseline can be passed to represent an average prediction on the scale of the SHAP values. Also a 3D array of SHAP interaction values can be passed as S_inter. A key feature of “shapviz” is that X is used for visualization only. WebbPlotting results. The package currently provides 4 plotting functions that can be used: Feature Contribution (Break-Down) On this plot we can see how features contribute into the prediction for a single observation. It is similar to the Break Down plot from iBreakDown package, which uses different method to approximate SHAP values.
