WebbThis may lead to unwanted consequences. In the following tutorial, Natalie Beyer will show you how to use the SHAP (SHapley Additive exPlanations) package in Python to get … WebbSHAP value (also, x-axis) is in the same unit as the output value (log-odds, output by GradientBoosting model in this example) The y-axis lists the model's features. By default, … 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. dewalt garage shelving
