Plot the decision surface of a decision tree on the iris
9 hours ago Plot the decision surface of a decision tree trained on pairs of features of the iris dataset. See decision tree for more information on the estimator. For each pair of iris features, the decision tree learns decision boundaries made of combinations of simple thresholding rules inferred from the training samples. We also show the tree structure

Decision Tree Regression — scikitlearn 1.0.1 documentation
6 hours ago Decision Tree Regression¶. A 1D regression with decision tree. The decision trees is used to fit a sine curve with addition noisy observation. As a result, it learns local linear regressions approximating the sine curve. We can see that if the maximum depth of the tree (controlled by the max_depth parameter) is set too high, the decision trees learn too fine details of the training data and
