摘要: 在一般支持向量机中,训练集的每个元素(xi,yi),i=1,2,…,l,对输入xi有确定的类别标号yi 。而在许多实际问题中,xi的类别往往是不确定的,常常是以概率zi+属于正类的概率zi-属于负类。针对这种实际情况,改造训练集,把原来的yi,用zi+,zi-代替,然后建立分类最优先模型,构建不确定中心支持向量机。

Abstract: In ordinary Support Vector Machine,for each elment(xi,yi),i=1,2,…,l of a training set,input of xi has a definite class number yi.While in practice,class of xi is rarely fixed,xi generally belongs to positive Class with probability of zi+ or xi generally belongs to negative class with probability of zi-.In that light,this paper has modified the training set,In which yi is replaced by zi+,zi- and classification optimal model and Uncertain Proximal Support Vector Machine are construct in turn.
