For binary classifying problem,we discuss the degeneracy of linear support vector machine(LSVM) which is applied for linearly separable or approximately linearly separable cases: derive necessary and sufficient conditions for the occurrence of degenerate solution and give their geometric explanations.
对二类分类问题,在线性可分或近似线性可分情况下,对线性支持向量分类机的平凡解进行了讨论,得出了解为平凡解的充要条件,说明了其几何意义,指出了避免出现这一现象的解决办法。
SP functions form a linearly separable series with a clear logical meaning and the set of PSP functions is only a special subset of SP functions.
SP函数是一类具有明确逻辑意义的线性可分结构系 ,PSP函数是SP函数的特殊子集 。
