Dear all!
I hope you can give me some answers on why my model is running for multiple hours and doesn't give any output.
I want to apply a SVM learner, I tried the normal SVM learner under Mining, the LIBSVM, the WEKA libSVM, SMO and the SMOreg. I tried all the SVM learner nodes I could find. The SMOreg node didn't work and the others run for a very long time.
Only the WEKA libSVM learner worked, however the WEKA predictor gave the error that there where no nominal or string variables. But i changed my predictor variable in a string so this was a realy strange error.
So I have 3 questions:
1. Are there more people that have the problem that it takes a long time, if so, how did you solve this?
2. What can I do so that the WEKA predictor doesn't give me this error anymore?
3. Is there a maximum in the usage of variables and/or cases for the SVM learners?
I really hope that you can help me!
