Mar 06, 2016 · I use the svm function in package e1071. As far as I understand, svm basic functionality can separate two linearly separable classes with an hyperplane (Support vectors). More …
https://stats.stackexchange.com/questions/270187/svm-why-does-the-number-of-support-vectors-decrease-when-c-is-increased
I am learning how to use libsvm through sklearn.svm in python. I read here about what happens and why when you change the C value as part of your model. My intuition from what I've learned would be that lower C values would use less support vectors to make a more general classification, while higher C values would use more support vectors to attempt to 'overfit' and account for all outliers.

Mar 22, 2016 · Lets say, we are given a training dataset of n points of the form A support vector is a vector of a datapoint xi that lies on the hyperplane(s) In order to choose the support vectors, we want to maximize the margin m and that implies we reduce the...

This is achieved by limiting the number of support vectors and by allowing support vectors (or, more precisely, basis functions) that are not necessarily training vectors. The new features of version V3.00 are described here. This implementation is an instance of SVM struct. More information on SVM struct is available here. Source Code

An alternative way to manage support vectors is to reduce their numbers during training by specifying a larger box constraint, such as 100. Though SVM models that use fewer support vectors are more desirable and consume less memory, increasing the value of the box constraint tends to increase the training time. Remove MdlSV and Mdl from the ...
