Shap summary_plot sort
WebbThe Shapley summary plot colorbar can be extended to categorical features by mapping the categories to integers using the "unique" function, e.g., [~, ~, integerReplacement]=unique(originalCategoricalArray). For classification problems, a Shapley summary plot can be created for each output class. WebbSHAP scores only ever use the output of your models .predict () function, features themselves are not used except as arguments to .predict (). Since XGB can handle NaNs they will not give any issues when evaluating SHAP values. NaN entries should show up as grey dots in the SHAP beeswarm plot. What makes you say that the summary plot is ...
