Interpretability

Train interpretable regression models and interpret complex regression models

Use inherently interpretable regression models, such as linear models, decision trees, and generalized additive models, or use interpretability features to interpret complex regression models that are not inherently interpretable.

To learn how to interpret regression models, see Interpret Machine Learning Models.
