WebbDecision plots can show how multioutput models arrive at predictions. In this example, we use SHAP values from a Catboost model trained on the UCI Heart Disease data set. There are five classes that indicate the extent of the disease: Class 1 indicates no disease; Class 5 indicates advanced disease. WebbTo visualize SHAP values of a multiclass or multi-output model. To compare SHAP plots of different models. To compare SHAP plots between subgroups. To simplify the workflow, {shapviz} introduces the “mshapviz” object (“m” like “multi”). You can create it in different ways: Use shapviz() on multiclass XGBoost or LightGBM models.
