 Dear all

I want to know how to use Knime for 

   SVM-RFE Recursive Feature Elimination with Support Vector Machines

and get the features ranked and the peforamnce

Hi Malik,

we don't have a dedicated node for this and I don't know the details of the implementation.

But you can use our Backward Feature Elimination Loop together with the SVM nodes?

Or this might be something for the Recursive Loops. Than you need to do the filtering on your own.

Hi Iris

Thanks for your reply. Do you know if your suggestion was implemented and where one can find it?

What about using the WEKA node?

Hi Malik,

no this was not implemented. It was just an idea :-)

Hi Iris
How i can get the coefficients of the attributes/features when applying SVM?
