will give a talk on

Abstract:
Data mining becomes a cutting-edge information technology tool in today’s competitive business world. It helps the company discover previously unknown, valid, and actionable information from various and large databases for crucial business decisions. This presentation provides a promising approach of data mining to classify the credit cardholders’ behavior through multiple criteria linear programming. After reviewing the history of linear discriminant analyses, we will describe first a model for classifying two-group (e.g., bankruptcy and current) credit cardholder behaviors. Then three-group (e.g., bankruptcy, delinquent, and current) and four-group (e.g., bankrupt charge-off, non-bankrupt charge-off, delinquent, and current) models will be illustrated. Besides the discussion of the modeling structure, we will utilize the well-known commercial software package SAS or Linux platform to implement these technologies by using a real-life credit card data warehouse. A number of potential business and financial applications will be finally summarized.
