WebApr 11, 2024 · Random Forest is an application of the Bagging technique to decision trees, with an addition. In order to explain the enhancement to the Bagging technique, we must first define the term “split” in the context of decision trees. The internal nodes of a decision tree consist of rules that specify which edge to traverse next. WebBuild a decision tree classifier from the training set (X, y). Parameters: X {array-like, sparse matrix} of shape (n_samples, n_features) The training input samples.
