Application of Exploring Decision Trees in Evaluation Subsystem in Intelligent Guidance System
Wen Li · Computer and Modernization · 2009
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.
