Hi,
I'm a student and I've just started using Knime. I've tried to make a sentiment analysis model using a MultiClassClassifier and a Weka Predictor, however a minute after the process starts I get an error saying: 'Cannot handle numeric class' and I really don't understand why this is happening. Any ideas or suggestions would be appreciated.
Thank you.
Regards,
IB
Hi ib381,
this is difficult to tell without seeing your workflow.
Weka nodes do need the exact columns as specified in the dialog. A multiclassclassfier can only predict categorical class columns and no numerical ones. You can convert them with the Number to String node.
Hope this helps,
Iris
