Reject inference in credit scoring using Semi-supervised Support Vector Machines

作者:

Highlights:

• Semi-supervised Support Vector Machines for reject inference are proposed.

• The method uses information of both the accepted and rejected applicants.

• The method deals with labelled and unlabelled classes of the outcome.

• The model is tested on real consumer loans with a low acceptance rate.

• Predictive accuracy is improved by the new model compared to traditional methods.
