Electric Power Marketing Data Mining Based on C5.0 Decision Tree Algorithm

In order to effectively mine the operation data from different departments in electric power enterprises,a decision tree algorithm of C5.0 is proposed and analyzed deeply,so as to provide valuable decision support information for managers.Firstly,the principle of advanced C5.0 decision tree algorithm in data mining is analyzed,and the original attribute selection method is improved by introducing information entropy,which improves the calculation speed of information gain ratio.Then,according to the designed sales relationship model,the data in the power plant management information system are mined.The experimental results on UCI machine learning data set and power marketing data set show that the improved C5.0 decision tree algorithm has good classification performance,and can quickly and accurately classify users in the power sales market,with an accuracy rate of 86.5%.
