Illustrates the decision tree classifier which is still important in data mining techniques for classifying, and discusses the algorithm of ID3 and C4.5 in decision tree inductive classification, and states that how to choose the decision attributes. Analyzes the algorithm implemen-tation by instance, results that the algorithm of C4.5 has many advantages compared with the algorithm of ID3, especially it is more cor-rect and reasonable on dealing with the data that have many attribute.
