| Abstract: | This thesis uses decision tree to analyze data for TV Station.Firstly a questionnaire is designed to allow the audiences to fill out and the surveys are the samples which are to be excavated.This thesis makes use of classical decision tree algorithm-C4.5,and constructs a decision tree from the sample set.By analyzing of the decision tree,the factors which can influence the TV ratings are got,and make programs reasonably. |
