Scott Hajek commented on MADLIB-1129:
-------------------------------------
[~fmcquillan], I like the interface you proposed. It works for the
classification case when you want to know which points were used for each
classification.
I've also had times where I just wanted to find the nearest neighbors but not
do any classification. You could still use this interface for that too, you'd
just have to provide a dummy label field. If there were an interface where you
don't have to provide a label field and just get the nearest neighbor IDs it
would be cleaner for that use case.
