Description:

In the Jupyter Notebook for Machine Learning Tutorial Python - 21: Ensemble Learning - Bagging (link to file), the parameter base_estimator used in BaggingClassifier is outdated.

###Suggested Fix:
Replace:

BaggingClassifier(base_estimator=DecisionTreeClassifier())

With:

BaggingClassifier(estimator=DecisionTreeClassifier())
