Embodiment Construction
[0038]The present invention will be further described below in conjunction with the accompanying drawings and specific preferred embodiments, but the protection scope of the present invention is not limited thereby.
[0039] Such as figure 1 As shown, the present embodiment is based on the credit rating method of the classification rule classifier, and the steps include:
[0040] S1.RIPPER rating model training: obtain the user credit information set used for model training, respectively extract the feature attributes corresponding to each information in the user credit information set to form a training set, and use the RIPPER classifier for training to obtain the RIPPER rating model;
[0041] S2. Credit rating: Input the credit information of the user to be evaluated and extract the corresponding feature attributes, input the extracted feature attributes into the RIPPER rating model for classification, and obtain the output of credit rating results.
[0042] RIPPER (rule in...
