Adjust model complexity
To make good predictions, you need to adjust the complexity of your model. Simple models can only represent simple data structures, while complex models can represent fine-grained data structures.
In this exercise, you are going to create trees of different complexities by altering the hyperparameters of a regression tree.
The training data chocolate_train is pre-loaded in your workspace.
