Tree-based AdaBoost regression

AdaBoost models are usually built with decision trees as the base estimators. Let's give this a try now and see if model performance improves even further.

We'll use twelve estimators as before to have a fair comparison. There's no need to instantiate the decision tree as it is the base estimator by default.
