A decision tree is a flowchart-like tree structure where an internal node represents a feature (or attribute), the branch represents a decision rule, and each leaf node represents the outcome. The topmost node in a decision tree is known as the root node. It learns to partition on the basis of the attribute value. Decision trees carry huge importance as they form the base of the Ensemble learning models in case of both bagging and boosting, which are the most used algorithms in the machine learning domain. Again due to its simple structure and interpretability, decision trees are used in several human interpretable models like LIME.
