title: Weka Attribute Selection
body: <p>I'm trying to perform Attribute Selection in Weka. I would like to use InfoGainAttributeEval as an evaluator, because I read that it is equivalent to mutual information, and Ranker as a search method. Should I perform attribute selection to both training and test set? Also, how can I choose the correct value for the N parameter?</p>
  
  <p>Thanks a lot for your time,</p>
