SVM 是 supervised learning(有监督学习)— classification(分类)中的一种,是在训练样本的特征空间求能把两类样本没有错误分开的最大间隔。对于样本数很少的情况将会得到很好的结果,即SVM适合小样本分类问题,是一个小样本方法 训练样本集分为 线性可分(画一条直线即可区分开○和×)和 非线性可分/线性不可分(无...
Support Vector Machines We first discuss a general mechanism for converting a linear classifier into one that produces non-linear decision boundaries. We then introduce the support vector machine, which does this in an automatic way. Classification with Non-linear Decision Boundaries ...
Top Abstract As machine learning techniques, support vector machines are quadratic programming models and are recent revolutionary development for classification analysis. Primal and dual formulations of support vector machine models for both two-class and multi-class classification are discussed. The dual ...
