Do you guys have experience with an efficient multiclass SVM package? I am currently using libsvm, but on 300k instances and 200 features it takes a very long time (24+ hours) to train.
Thanks!

what kind of kernel do you need? – fatih Jan 27 '14 at 10:50

Try this: http://www.loria.fr/~lauer/MSVMpack/ It is very user friendly and uses all available cores on the machine. – soufanom Jan 28 '14 at 13:42

I am using a RBF kernel. Thanks soufanom for the pointer, I will check out MSVMpack. – langLord Jan 29 '14 at 00:14

With that dimension and that many examples you might not be in luck using an RBF kernel. I would give it a try with the linear kernel or with LIBLINEAR (http://www.csie.ntu.edu.tw/~cjlin/liblinear/)
