C4.5 is an algorithm used to generate a decision tree developed by Ross Quinlan. C4.5 is an extension of Quinlan's earlier ID3 algorithm. The decision trees generated by C4.5 can be used for classification, and for this reason, C4.5 is often referred to as a statistical classifier. In 2011, authors of the Weka machine … See more C4.5 builds decision trees from a set of training data in the same way as ID3, using the concept of information entropy. The training data is a set $${\displaystyle S={s_{1},s_{2},...}}$$ of already classified samples. Each sample See more Quinlan went on to create C5.0 and See5 (C5.0 for Unix/Linux, See5 for Windows) which he markets commercially. C5.0 offers a number of improvements on C4.5.

WebMar 6, 2024 · Tree algorithms: ID3, C4.5, C5.0 and CART: CART ( Classification and Regression Trees) is very similar to C4.5, but it differs in that it supports numerical target variables (regression) and does not compute rule sets. CART constructs binary trees using the feature and threshold that yield the largest information gain at each node.
