WebStacking is an ensemble learning technique to combine multiple classification models via a meta-classifier. The StackingCVClassifier extends the standard stacking algorithm (implemented as StackingClassifier) using cross-validation to prepare the input data for the level-2 classifier. WebFirst of all, the estimators need to be a list containing the models in tuples with the corresponding assigned names. estimators = [ ('model1', model ()), # model () named model1 by myself ('model2', model2 ())] # model2 () named model2 by myself Next, you need to use the names as they appear in sclf.get_params () .
