One-class support vector machine (OC-SVM) is a common algorithm to solve one-class classification (OCC) problem. Weighted OC-SVM (WOC-SVM) is an improved algorithm based on OC-SVM, which assigns a weight to each sample through a specific weight calculation method so as to improve the ...
One-Class Support Vector Machine在过去20里逐渐流行,就是为了解决这样的问题。本篇博客对One-Class SVM进行介绍,而One-Class SVM也会应用到我的论文中。 1. Just One Class? 首先先看下我们的问题,我们希望确定新的训练数据是否属于某个特定类?怎么会有这样的应用场景呢?比方说,我们要判断一张照片里的人脸,...
看原理就懂了,下面给大家讲SVDD的原理,SVDD是叫support vector domain description,想必你第一反应就是想到support vector machine(SVM),的确,它的原理和SVM很像,可以用来做one class svm,如果之前你看过SVM原理,那么下面的讲解你将会感到很熟悉。凡是讲模型,都会有一个优化目标,SVDD的优化目标就是,求一个中心为a...
Among the variety of methods and algorithms proposed to deal with this problem, boundary based methods include One-class support vector machine (OC-SVM) is considered as an effective and outstanding one. Nevertheless, extremely sensitivity to the presence of outliers and noises in the training set...
