A Multi-criteria Convex Quadratic Programming model for credit data analysis

Speed and scalability are two essential issues in data mining and knowledge discovery. This paper proposed a mathematical programming model that addresses these two issues and applied the model to Credit Classification Problems. The proposed Multicriteria Convex Quadric Programming (MCQP) model is highly efficient (computing time complexity O(n(1.5-2))) and scalable to massive problems (size of O(10(9))) because it only needs to solve linear equations to find the global optimal solution. Kernel functions were introduced to the model to solve nonlinear problems. In addition, the theoretical relationship between the proposed MCQP model and SVM was discussed. (c) 2007 Elsevier B.V.
