改进的C4.5算法的研究与应用
Research and Application of Improved C4.5 Algorithm
摘要
Abstract
In view of the research on the construction of the characteristic decision tree method of the existing C4.5 algorithm, it is found that the method has low accuracy,which leads to the lack of convenience in the use of the model. Therefore,in-depth study of the C4.5 algorithm in the process of data mining,this paper proposes an improved algorithm,namely C4.5-W algorithm, the main idea of the algorithm is the C4.5 algorithm in parameter W is introduced,the adjustment measure attribute information gain ratio range,so as to construct the decision tree model to find out the characteristics of people forecast. The experiment shows that the algorithm can effectively improve the accuracy of the predicted person involved in the process of use. Therefore,the C4.5-W algo?rithm can improve the accuracy of the decision tree model.关键词
