WebA 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. WebDecision trees leaf creation. When making a decision tree, a leaf node is created when no features result in any information gain. Scikit-Learn implementation of decision trees allows us to modify the minimum information gain required to split a node. If this threshold is not reached, the node becomes a leaf.
