Specific embodiment
Below in conjunction with attached drawing in the embodiment of the present invention, technical solution in the embodiment of the present invention carries out clear, complete
Ground description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Usually exist
The component of the embodiment of the present invention described and illustrated in attached drawing can be arranged and be designed with a variety of different configurations herein.Cause
This, is not intended to limit claimed invention to the detailed description of the embodiment of the present invention provided in the accompanying drawings below
Range, but it is merely representative of selected embodiment of the invention.Based on the embodiment of the present invention, those skilled in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
It should be noted that for the ease of difference, herein, the personal reference report name that People's Bank of China is provided
It is reported for personal reference, and the report that the method through the embodiment of the present invention generates is named as personal reference backtracking report.
Referring to Fig. 1, the present embodiment has illustratively provided a kind of personal reference report retrogressive method, this method include with
Lower step:
Step 1, the credit information of each body of the report is obtained.The body of the report is to refer to being queried for personal reference report
Person, i.e. individual subscriber, credit information can be obtained from each business bank or associated mechanisms, i.e., from being arranged in business bank or phase
It is obtained in the server of shutting mechanism.
Step 2, it is directed to each body of the report, based on the credit information of this report main body, seeks this report main body
Risk rating.Specifically, it can realize in the following ways:
It is comprehensive to multiple dimensions of each loan of the body of the report to carry out risk mapping, it takes in the multiple dimension most
The risk rating that high-risk grade is provided a loan as this chooses the risk rating maximum value of all loans as this report main body
Risk rating.
As an example, the multiple dimension may include four dimensions, be longest continuously overdue issue, account status respectively
(normally, close, produce, is overdue, bad accounts), five-category (normally, pay close attention to, is secondary, suspicious, lose, is unknown), special deal
(duration of an exhibition, guarantor go back, pay a debt with the capital, payment beforehand, producing, other in generation), risk class can be preferably divided into 0-5 totally 6 etc.
Grade can carry out risk mapping according to rule as shown in Figure 2.Longest therein continuously overdue issue, account status and Pyatyi
These three dimensions of classifying can individually carry out risk mapping, and for special deal, then it can be continuously overdue in conjunction with longest
Issue is comprehensive to carry out risk mapping, for example, if the type of transaction of special deal is " guarantor's generation is also " or " paying a debt with the capital ", wind
Dangerous grade is mapped as 5, and for another example, if the type of transaction of special deal is " duration of an exhibition ", and continuously overdue issue is not the longest provided a loan
0, then risk class is mapped as 4, if the type of transaction of special deal is " duration of an exhibition ", and continuously overdue issue is 0 to the longest provided a loan,
Then risk class is mapped as 0.
Citing, the credit information based on certain body of the report obtain the longest of a certain pen loan continuously overdue issue, account shape
State, five-category, special deal this four dimensions risk class be respectively 3,3,4,2, then the pen of this report main body is borrowed
The risk rating of money is 4, and this report main body is provided a loan for 3 totally, and in addition the risk ratings of two loans are respectively 2,3, then should
The risk rating of the body of the report is 4.
Step 3, the risk rating of all body of the report is sought out according to step 2.
Step 4, risk rating cut-off is set, risk rating is lower than to the body of the report mark of the risk rating cut-off
Knowing is white label (or being white list), and the body of the report equal to or higher than the risk rating cut-off is identified as black label
(or being blacklist).
Generally, when setting risk rating cut-off, the risk partiality according to business demand is needed, suitable risk is selected
Grading cut-off.For example, the risk partiality of small amount consumer credit class loan is provided a loan higher than wholesale home mortgage class, the former can be selected
It selects 3 and is used as risk rating cut-off, the latter can choose 2 and be used as risk rating cut-off.Under normal conditions, risk rating cutting
Point suggests being selected as 2 or 3 (the case where being directed to 6 risk class).Too low risk rating cut-off to noise-sensitive,
The accuracy of model is reduced when constructing Credit Model, excessively high risk rating cut-off is excessive to signal screening, can reduce model
Applicability.
Step 5, setting backtracking time point and backtracking rule, are recalled according to the backtracking rule, generate backtracking time point
Personal reference backtracking report, individual's reference backtracking report has sample identification, specifically, being identified as the report of white label
The personal reference backtracking report of main body is identified preferably sample, is identified as the personal reference backtracking report of the body of the report of black label
Announcement is identified as bad sample.The personal reference backtracking report of generation can be exported to the service of the lending agencies such as each business bank
In device, using the sample as building Credit Model.Or it can also be in personal reference backtracking report component of the local based on generation
After good Credit Model, output carries out credit evaluation for the server in the server of the lending agencies such as each business bank.
For white label, any loan is normally to provide a loan, it is possible to when selecting the granting of any loan
Between as backtracking time point.For black label, the loan that only risk rating is higher than risk rating cut-off is only abnormal loan, and
Loan is only the judgement reason for causing this report main body to be identified as black label extremely for these, therefore can only select any risk
Grading is higher than the Time Of Release of the loan of risk rating cut-off as backtracking time point.Therefore in this step, for recalling time point
Setting the Time Of Release of any loan can be set as backtracking time point for white label, and for black label, then
Need to set Time Of Release of any risk rating higher than the loan of risk rating cut-off as backtracking time point.
And as more preferably set-up mode, for white label, it can choose the granting of the loan of loan time the latest
Time is as backtracking time point;For black label, can choose the loan time the latest and risk rating be higher than risk rating cutting
The Time Of Release of one loan of point is as backtracking time point.The loan of selection loan time the latest, i.e., selection is near existing
The backtracking time, can farthest reduce as information backtracking caused by historical information lose, guarantee establishing credit
There is information as much as possible can use when model.
Backtracking rule described in this step refers to that included field is reported in personal reference backtracking.Personal reference backtracking report
Field in announcement can be arranged with reference to the field in personal reference report, i.e., to whole fields in the report of personal reference, first
Determine which field is not influenced and can be retained by recalling, the influence which field will receive backtracking can not retain and can only delete
It removes, which field is influenced but can retain and need to do correspondingly to adjust by recalling.For example, loan principal balance field is
Dynamic field, can with refund carry out and change because can not know the refund behavior of the specific body of the report, thus the field without
Method retains, and needs to delete.Loan agreement amount field, be static fields, just had determined that in loan origination and will not with also
Money carries out and changes, therefore the field can retain, and be not required to adjust.Loan status deadline field, the generation dependent on report
Date can be known, therefore the field can protect after the backtracking time of report has been determined (date of formation of i.e. new report)
It stays, but needs to adjust.In addition, to whole records in the report of personal reference, record occurs between backtracking time point and current time point
Need to delete, record is that can retain before recalling time point occurs.
In this step, the generating mode of personal reference report is copied, according to backtracking rule, the first personal basic letter of backtracking
Then breath recalls credit transaction information, then summarized again based on the information after these backtrackings for informative abstract, then recalled public
Information finally recalls query information.The final personal reference backtracking report for obtaining backtracking time point end to end plus report.
Different backtracking time point available more part personal reference backtracking reports of one body of the report in reality, but
The generally unified a individual's reference time for use (Time Of Release of a nearest loan is as backtracking time point) the latest in practical application
It traces back report, ignores other personal reference backtracking reports earlier.So in practical applications, the body of the report and its people's reference are returned
One-to-one relationship is presented in report of tracing back.
Report that the difficult point that assessing credit risks is carried out to establish quantitative model is according to personal reference at present: 1) in individual
Reference report generation time point, i.e., before loan origination, the not no black and white tag identifier of the body of the report, thus can not be according to supervised learning
Method personal reference is modeled, afterwards can not before loan origination to application main body carry out default risk assessment.2)
Due to whether breaking a contract the generation of this event after offering loans, it is contemplated that answering utilization of a loan to the actual effect of reference report
Collage-credit data before granting is modeled, if still using after offering loans reference report modeling, will affect reference for
The accuracy of risk assessment.And the middle above method, the personal reference backtracking that specified time point can be generated are reported through this embodiment,
And the sample identification of good bad sample is had in report, i.e. the body of the report has black/white label, provides for building Credit Model
Sample is supported, may be implemented to construct Credit Model by machine learning method, is conducive to the accuracy for improving credit evaluation.
Using the present embodiment above method, sample set when building Credit Model can be expanded first.By taking XX project as an example,
By analyzing the distribution characteristics of user, filter out two datasets: 1) the personal reference report generation time loan origination just
User in negative a quarter loan period, including the white label of the black label in 107 families and 535 families.2) reference report generation
The user in a quarter period to 3 years after loan origination time, including the white label of the black label in 277 families and 1385 families.The
The reference report of a kind of user group can be used directly to measure the reference state of applicant at that time.Due to the second class customer group's
Reference report generally lags behind loan origination time point, can not accurately describe applicant in the reference state of loan origination time point.
Using the reference retrogressive method stated herein, reference report is pushed back into loan origination time point, reduces use to the full extent
Reference state of the family before loan origination time point, has expanded modeling sample significantly, has preferably depicted the feature between black/white label
Difference plays major contribution for the foundation of subsequent Credit Model.
Variable and explained variable secondly can be explained using this method to model in the supervised learning of identical time point.With
For YY project, 18 black labels are defined with 3 for risk rating cut-off to 877 samples of total amount.Based on the sample set
It is total to construct six credit history, overdue history, debt burden, contractual capacity, financial strain, recent credit demand Index modules
45 indexs are counted, as shown in Figure 3.Final logistic regression and random forests algorithm in supervised learning method, Credit Model
Performance on test set, (Area Under of the Curve of ROC, as area under ROC curve, value exist AUC
0-1, if a white label and black label are randomly selected in AUC expression, model correctly judges that the value of black label is higher than the value of white label
Probability, AUC=0.5 indicates that random guess, model do not have a separating capacity, and AUC is higher than 0.5, and the area for indicating model closer to 1
Point ability is higher) be 0.6 or so, KS (Kolmogorov-Smirnov is examined, to examine two experiences distributions whether different,
Whether the distribution i.e. to the distribution and white label of examining black label is different, and the difference of good black label distribution is bigger, and KS value is bigger,
The separating capacity of model is stronger) it is 0.4 or so, show the personal reference obtained using the method for the present invention backtracking report as sample
It is trained, the Credit Model constructed separating capacity with higher, it can credit relatively accurately is carried out to individual and is commented
