WebJan 2, 2024 · Scikit-Learn version 0.22 introduced StackingClassifier and StackingRegressor classes, which aggregate multiple child estimators into an integral whole using a parent (aka final) estimator. Stacking is closely related to voting. The main difference is about how the weights for individual child estimators are obtained. WebStacking is provided via the StackingRegressor and StackingClassifier classes. Both models operate the same way and take the same arguments. Using the model requires …
