Information gain calculator decision tree
Information gain is the basic criterion to decide whether a feature should be used to split a node or not. The feature with the optimal split i.e., the highest value of information gain at a node of a decision tree is used as the feature for splitting the node. The concept of information gain function falls under the C4.5 algorithm for generating the decision trees and selecting the optimal split for a decision tree node. Some of its advantages include: Web26 apr. 2024 · A decision tree is a logical model that helps you make a prediction based on known data.
