SVM attributes weights

[Damian.s]

Hi All,
Is there a way to extract weights of attributes from LibSVM ?
I've seen the class SVMAttributeEval, but it only gives ranking. What's more, I can't get it separated for each class (except doing manual one-vs-all).

Thanks.
Damian.

Did you try using the LibSVM classifier directly?

Hi.
As far as I know LibSVM doesn't give attributes' weights as output.
