    May 31, 2017 Decision Tree Classifier in Python using Scikit-learn. Decision Trees can be used as classifier or regression models. A tree structure is constructed that breaks the dataset down into smaller subsets eventually resulting in a prediction. There are decision nodes that partition the data and leaf nodes that give the prediction that can be followed by traversing

    Jun 22, 2020 A 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 to the leaf, the sample is propagated through nodes, starting at the root node. In each node a decision is made, to which
