Abstract

Abstract:

This paper presents the characters of intelligent guidance system, and describes the principles of C4.5 algorithm of exploring decision trees, builds a model which is used to evaluate the effect of students’ study on line. Using classify rules from the models, the system predicts, some data and a form of accuracy evaluation are given which empirically shows to be more efficiency in computational efficiency and more flexibility in algorithm.

Key words: intelligent guidance system, exploring decision trees, C4.5 algorithm, data mining
