Question concerning the CFS attribute selection

Hello everyone,

I wondered if in case the locallyPredictive option of CFSSubsetEval is
turned off, will the class label still be considered in the evaluation???
Or will it just consider the correlation between two features without
knowing the actual class?

Is there another way in weka to exclude highly correlated features?

Thanks in advance,

Cheers,
Sebastian

CFS is a supervised attribute selection method. It has to consider  
the class.
