WebbBy default a SHAP bar plot will take the mean absolute value of each feature over all the instances (rows) of the dataset. [60]: shap.plots.bar(shap_values) But the mean absolute value is not the only way to create a global measure of feature importance, we can use any number of transforms. WebbShapley values may be used across model types, and so provide a model-agnostic measure of a feature’s influence. This means that the influence of features may be compared across model types, and it allows black box models like neural networks to be explained, at least in part. Here we will demonstrate Shapley values with random forests. hilkka kirjautuminen
