An Improved C4.5 Algorithm and Its Application on Customer Value Analysis

Abstrcat The key to the management of a modern company is the customer value analysis. The classification algorithm can deal with this analysis very well. The Decision Tree Algorithm, especially C4.5, is an important kind of classification algorithm. However, C4.5 Algorithm has some shortcomings in accuracy. An improved and C4.5 based algorithm is introduced by adding boosting techniques, which thus improves accuracy. The paper uses the new algorithm to analyze supermarket customer data. The experiment proves that the accuracy of the improved algorithm is better than C4.5.
