SVM & Nomogram Problem

Postby Guest » Sun Aug 27, 2006 8:27

Hi, I'm getting an error message each time I try to use the nomogram visualization for the SVM. Am I doing something incorrectly? Thank you!

Make sure that you check the "For nomogram if possible" check box in your SVM. This is used in current version of a SVM widget as a temporary fix, and uses a SVM as implemented by Aleks (http://ai.fri.uni-lj.si/~aleks/orng/). We have recently newly ported the SVM to Orange (used when above button is not checked), but have yet to include the support for nomograms.
