4.3
C4.5 is a series of algorithms used in machine learning and data mining. Its goal is supervised learning: given a data set, each tuple can be described by a set of attribute values, and each tuple belongs to one of the mutually exclusive categories. The goal of C4.5 is to find a mapping from attribute value to category through learning, and this mapping can be used to classify new entities with unknown category.
