WebClones the classifiers for stacking classification if True (default) or else uses the original ones, which will be refitted on the dataset upon calling the fit method. Hence, if use_clones=True, the original input classifiers will remain unmodified upon using the StackingClassifier's fit method. WebStack of estimators with a final classifier. Stacked generalization consists in stacking the output of individual estimator and use a classifier to compute the final prediction. …
