【Abstract】 According to the particular property of text categorization, this paper carefully analyzes the theory of least squares support vector machine and constructs a multiclass text classifier based on least squares support vector machine. The experiments show that this classifier can improve the training efficiency and preserve the high precision and recall. This method of multiclass text categorization is workable.更多还原
