Value of C in EVOSVM

c1borg

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.

.

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.

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.
