漫谈支持向量机(support vector machines,SVM ) 第一部分、概述 支持向量机(support vector machines,SVM) 一种二分类分类模型。 基本模型:定义在特征空间上的间隔最大的线性分类器 学习算法:求解凸二次规划的最优算法。 学习策略:间隔最大化,可形式化为一个求解凸二次规划(convex quadratic programming)的问题,也...
在超平面的描述中和等式(1.1)(1.2)中出现的向量ω被称为超平面的法相量(normal vector),标量b被称为超平面的截距(intercept),其中法向量ω决定了向量空间中超平面的方向(原文为orientation),||ω||和b的比值(并非由b单独决定)决定了超平面与向量空间Rn的原点之间的距离。法向量ω与所有与超平面平行的向量正交(感...
