I'm looking to implement a linear and non-linear SVM in R but having some confusion over which argument to use in
svm(). For the linear SVM I want to add in the penalty $\gamma$ for soft margin. This is the
gamma = argument, correct? How is it different from the
cost = or
epsilon = argument?
Secondly, under the RBF kernel in the non-linear SVM, what is the sigma/bandwidth argument called?
