Abstract
On the basis of the traditional SVM principle and a "one-by-one" classifier constructing strategy, a new multi-class SVM, named Binary Tree Multistage Support Vector Machine (BTMSVM), is proposed. This classifier is simple and results in less duplicating training samples. The credits of 96 listed companies of China in 2000 are evaluated with this SVM credit scoring model, and the simulation results show that a high classification accurate rate of up to 98.11% is attained.
