A SOM-Based Framework for Regional Segmentations of Customers

Segmentations of customers gained in one area could not be used to predict customers' characteristics in other areas, because regional influences on customers were different. This paper proposed a self-organizing map framework to get regional segmentations of customers. In order to verify the validity of this framework, it was applied to the credit card holders of a famous bank in China. Examination results demonstrated that this framework could get reliable regional segmentations of customers.
