Shap plots bar
WebbSometimes it is helpful to transform the SHAP values before we plots them. Below we plot the absolute value and fix the color to be red. This creates a richer parallel to the standard shap_values.abs.mean(0) bar plot, since the bar plot just plots the mean value of the dots in the beeswarm plot.

WebbCreate a SHAP dependence scatter plot, colored by an interaction feature. Plots the value of the feature on the x-axis and the SHAP value of the same feature on the y-axis. This shows how the model depends on the given feature, and is like a richer extenstion of classical parital dependence plots.

Also a 3D array of SHAP interaction values can be passed as S_inter.
