WebbLightGBM Documentation Decision Tree is a supervised algorithm used in machine learning. It is using a binary tree graph (each node has two children) to assign for each data sample a target value. The target values are presented in the tree leaves. To reach the leaf, the sample is propagated through nodes, starting at the root node.
