The blank still sort of concerns me. I remember mention in the past that the CSV conversions sometimes had problems. I might still suggest getting the date into the format indicated in the arff spec yourself might be an idea. I think it mentioned any format that would work with java SimpleDateFormat. But I usually preprocess csv files in R and convert to arff with RWeka. I haven’t done that a lot for dates. I’m not sure what the dateAttributes in the GUI actually means. _______________________________________________ Wekalist mailing list -- [email protected] Send posts to [email protected] To unsubscribe send an email to [email protected] To subscribe, unsubscribe, etc., visit https://list.waikato.ac.nz/postorius/lists/wekalist.list.waikato.ac.nz List etiquette: http://www.cs.waikato.ac.nz/~ml/weka/mailinglist_etiquette.html
