Value of C in EVOSVM

Question

Hi what would be a good starting value for the C parameter when starting to use the EVOSVM learner, I am using 0,0 and its still running after 11 hrs.  Failing this can I use grid parameter optimisation in RM and if so how.

Thanks guys for the excellent info.

Hi,
the EvoSVM has many advantages, but it has a great disadvantage about the other SVM implementations: It's a little bit slower. If you need greatest performance, you should change to the LibSVM or JMySVM if you don't need the specialties of the evolutionary approach.

What is remarkable about your question is that there is an example of C optimisation for SVM in the samples! Can you not find it? For values of C check out http://www.csie.ntu.edu.tw/~cjlin/papers/guide/guide.pdf.
