摘要
In order to conquer the hard outputs defect of Support Vector Machine (SVM) and extend its application, an improved target recognition method based on Multi-class Support Vector Machine (MSVM) is proposed. Firstly, the typical Probability Modeling methodologies of MSVM were deeply analyzed. Secondly, the structure of one-against-one multi-class method which matches with Basic Probability Assignment (BPA) outputs of evidence theory by coincide, so a special Multi-class BPA output method is derived, and multi-sensor target recognition model based on MSVM and two-layer evidence theory is constructed. Finally, the results of experiments show that the proposed approach can not only conquer the overlap area of one-against-one multi-class method, but also improve classification accuracy.
