★ ★ ★ ★ ☆

Actually, RBF is the default kernel used by SVM methods in scikit-learn. Random Forests When used for regression, the tree growing procedure is exactly the same, but at prediction time, when we arrive at a leaf, instead of reporting the majority class, we return a representative real value, for example, the average of the target values.
