WebNov 26, 2024 · The documentation on sklearn for StackingClassifier says: Base estimators which will be stacked together. Each element of the list is defined as a tuple of string (i.e. name) and an estimator instance. An estimator can be set to ‘drop’ using set_params. So a correct list would look the following: http://rasbt.github.io/mlxtend/api_subpackages/mlxtend.classifier/

http://onnx.ai/sklearn-onnx/_modules/skl2onnx/_supported_operators.html 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 () .
