基于孪生支持向量机的二叉树多分类 结合TSVM，依据类间距和类内距离构建二叉树的层次结构-TSVM MATLAB

多分类孪生支持向量机,主体是-1 1的2分类孪生支持向量机，采用onevsone改编成多分类的孪生支持向量机(multi classification twin support vector machine, kernel code is binary-classification twin support vector machine ,constructed it as a multi classification twin support vector machine by using O
