Machine learning decision tree.

This grid search builds trees of depth range 1 → 7 and compares the training accuracy of each tree to find the depth that produces the highest training accuracy. The most accurate tree has a depth of 4, shown in the plot below. This tree has 10 rules. This means it is a simpler model than the full tree.
