Decision Trees in Machine Learning (ML) with Python Tutorial

This tutorial's code is available on Github and its full implementation as well on Google Colab. A decision tree is a vital and popular tool for classification and prediction problems in machine learning, statistics, data mining, and machine learning [4]. It describes rules that can be interpreted by humans and applied in a knowledge system such as databases. It classifies cases by commencing at the tree's root and passing through it unto a leaf node. A decision tree uses nodes and leaves to make a decision.
