Support Vector Classifier 可以看到mmc其实已经有了相当好的分类方向,为什么不能称呼其为分类器呢?其原因也许在于它无法处理所有的数据。在某些情况下,我们无法找出哪怕一条hyperplane来分类数据。在这种情况下,引出了support vector classifier, 也被称为soft margin classifier。其意义在于允许一些点进入margin的范围,甚至...
所谓的support vector machine其实是一种叫做maximal margin classifier分类器的泛化。本篇将按照以下顺序来介绍: 介绍Maximal Margin Classifier,一种适用于线性数据的二分类学习器 介绍Support Vector Classifier,对于1的一种衍生,可以用于更广阔的的分类任务 介绍Support Vector Machine 基于2的进一步亚盛,可以用于非线性的...

In support vector classifier, asymmetric kernel functions are not used so far, although they are frequently used in other kernel classifiers. The applicable kernels are limited to symmetric semipositive definite ones because of Mercer's theorem. In this paper, SVM is extended to be applicable to ...
4. When the data are 3 dimensional, the support vector classifier is a 2-dimensional plane. In mathematical jargon, a plane is a "flat affine 2-Dimensional subspace". When the data are in 4 or more dimensions, the Support Vector Classifier is a hyperplane. In mathematical jargon, a hyperp...
