寒假闲来无事,阅读了些文章重新温故一下概念,发现我之前所理解的支持向量机(support vector machine)和支持向量分类器(support vector classifier)严格上来说不是同一个东西。严格的来说支持向量机是支持向量分类器的一个拓展。如果更细的划分,支持向量分类器其实又是maximal margin classifier的一个拓展。因此概括的来...
无法解决线性不可分的情况,即如果不存在分离平面,那么最大边际分类器就失效了。 鲁棒性较差。如果添加一个观测数据,可能会导致最大边际超平面产生较大变化。 针对这两个问题,引入支持向量分类器(Support Vector Classifier)。其大致思想是:以小范围的错误,换取更大范围的正确。即边际未必完美地将数据分离成两类,允许...
图2-5中 H 1 H1在这些训练样本上表现不佳,本身就带有分类错误; H 2 H2和 H 3 H3如果作为这个二分类问题的线性模型,在训练集上的表现是完美的。然而,这些分类模型最终都是要应用在未知分布的测试数据集上,因此我们更加关注如何最大限度的为未知分布的数据提供足够的待预测空间。比如,有一个黑色样...
The SVM classifier is created like so: C# Copy var svm = new SupportVectorMachine("poly", 0); svm.gamma = 1.0; svm.coef = 0.0; svm.degree = 2; The “poly” argument is really a dummy value because the SVM is hardcoded to use a polynomial kernel function. The 0 argument is a...
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 ...
