Jeff Eastman commented on MAHOUT-284:
-------------------------------------
This patch is obsolete and after a couple of hours trying to apply it manually
have given up. It has a lot of special case tests for strongCluster and
corresponding branching to avoid dividing by zero in the computeProbWeight
calculation (which currently has the only test for distance == 0, substituting
1e-10). I wonder about the importance of fixing this in general, but would like
to keep looking for a more elegant solution that doesn't involve so much
special case testing.
