Improved polynomial SVM classifier for text categorization
一种改进的多项式核支持向量机文本分类器 *

Polynomial kernel is investigated and widely used for text categorization because of it's high generalization perfor-mance.For the polynomial kernel low study performance's fault,this paper combined conditionally positive definite kernel which had high study performance with polynomial kernel as an improved polynomial kernel.The experiment results show that the improved polynomial kernel SVM classifier for text categorization is superior to polynomial kernel SVM classifier for text categorization.
