WebDec 10, 2024 · We create a StackingClassifier using the second layer of estimators with the final model, namely the Logistic Regression. Then, we create a new StackingClassifier with the first layer of estimators to create the full pipeline of models. As you can see the complexity of the model increases rapidly with each layer.

In recent versions, these modules are now under sklearn.model_selection, and not any more under sklearn.grid_search, and the same holds true for train_test_split ( docs ); so, you should change your imports to: from sklearn.model_selection import RandomizedSearchCV from sklearn.model_selection …
WebWhen using the ‘threshold’ criterion, a well calibrated classifier should be used. k_bestint, default=10 The amount of samples to add in each iteration. Only used when criterion='k_best'. max_iterint or None, default=10 Maximum number of iterations allowed. Should be greater than or equal to 0.
