| Outline of Final Research Achievements |
The purpose of this research is to develop novel technology to detect fraudulent transactions in the mail-order industry with the Informatics. In order to compensate for the working experiences, conventional technology, such as pattern identification was employed. In this study, analyses were performed based on the transaction recode came from a mail-order company. As a result, the weak learners have high generalization performance of detection accuracy. The results of this research can be expected to 1) improve the accuracy of credit management at the time of shipment, and 2) The risk of post-payed systems for the mail-order companies will be reduced.
