> Whatever is parsing the ARFF file for the ARFFVectorIterable (As far as I can
> tell, it's the class itself) doesn't handle '?' as a marker for unknown
> value. See: http://www.cs.waikato.ac.nz/~ml/weka/arff.html
> I just started looking at Mahout classifiers this week, so I'm not sure how
> to handle this yet. If I figure it out, I'll post a patch, but until then,
> guidance would be helpful!
