How can I determine w.x+b? What I mean is does w,x refer to in svm? Also, the rest of the properties that model struct holds is unclear to me. I am talking in the context of libsvm in matlab?
A nice tutorial on SVM can be found at
http://www.autonlab.org/tutorials/svm.html
Take a look at these documents for details on LIBSVM
