| Abstract: | According to different application, the computation formulas of information entropy were improved. These formulas to choose evaluating indexes and acquire their evaluation weight were applied. Based on decision tree that created by utilizing information gain, the detail rules of indexes rating were given. Finally, through constructing credit risk evaluating system of individual housing loan, the practicality of these methods was proved. |
