First, they allow redundant test of boolean variables to be omitted. For example, in the tree for x 1 ∧ x 2, both branches in the test of x 2 on the left lead to 0, so there really is no need to test x 2 at all. We can simplify this WebExamples: Decision Tree Regression. 1.10.3. Multi-output problems¶. A multi-output problem is a supervised learning problem with several outputs to predict, that is when Y is a 2d array of shape (n_samples, n_outputs)..
