Hello all, In my research work I need to go for RBF kernel in SVM classification and I do not want to use inbuilt function. So I had composed the RBF function on my own as shown below. My query is that I am not getting how do we include the values of kernel parameter C in this function . Any help in this regard will be highly appreciated.
function G = myrbf(U,V)
gamma = 0.016;
sig = 1/sqrt(gamma);
c = 0.18;
G = exp(-((norm(U-V))^2)/(2*(sig^2)));
end
where U and V receives the training features (dimension 10000 X 2) and training label (10000 X 1) respectively.
