Extra tree python
WebWhat is extra tree classifier in Python? Extra trees (short for extremely randomized trees) is an ensemble supervised machine learning method that uses decision trees and is used by the Train Using AutoML tool. See Decision trees classification and regression algorithm for information about how decision trees work. WebAn extra-trees regressor. This class implements a meta estimator that fits a number of randomized decision trees (a.k.a. extra-trees) on various sub-samples of the dataset and uses averaging to improve the predictive …
