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...

Tax et al. first introduced a method of adapting the support vector machine (SVM) methodology to the one-class classification problem, called support vector data description (SVDD). In this paper, we incorporate the concept of fuzzy set theory into the SVDD. We apply a fuzzy membership to ...

inspired by the support vector machine by Vapnik, called the support vector domain description (SVDD). This data description can be used for novelty or outlier de- tection. A spherically shaped decision boundary around a set of objects is constructed by a set of support vectors describing the ...

After selecting the SV machine type, the user must decide which kernel to use. 3.5 Setting the Kernel Type Option 2 from the SV machine parameters menu allows the kernel type to be chosen. For a detailed description of the kernel types see the appendix. The menu will look like this: ...
