Gibb's sampling implementation
------------------------------

                 Key: MAHOUT-29
                 URL: https://issues.apache.org/jira/browse/MAHOUT-29
             Project: Mahout
          Issue Type: New Feature
            Reporter: Isabel Drost


Copied over from original issue:

> EM clustering can also be changed very slightly by assigning points to single 
> clusters chosen at random according to the probability of membership. This
> turns EM clustering into Gibb's sampling. The important property that is 
> changed is that you now can sample over the distribution of possible samplings
> which can be very important if some parts of your data are well defined and 
> some parts not so well defined.
