Abstract: AUC(Area Under the ROC Curve)evaluation criterion is widely used to measure the performance of classification algorithms in binary datasets. In this papaer, fistly we introduce the SVM Multi-class classification method; then we systematically introduce the AUC method; finally, we use the experiments to compare the AUC of various SVM Multi-class classification method in Multi-class datasets. The results indicated that the AUC value is closely related with the kernel functions and multi-class transformation method.

Key words: SVM, AUC, Kernel Functions, Multi-class transformation method
