Currently, SVMs don't have built-in multiclass support. Logistic Regression supports multiclass, as do trees and random forests. It would be great to add multiclass support for SVMs as well. There is some ongoing work on generic multiclass-to-binary reductions: https://issues.apache.org/jira/bro

Hi Robert, I would say, taking the sign of the numbers represent the class of the input-vector. What kind of data are you using, and what kind of traning-set do you use. Fundamentally a SVM is able to separate only two classes, you can do one vs the rest as you mentioned. I don't see how LVQ can
