Ted Dunning commented on MAHOUT-668:
------------------------------------
So sorry... I didn't look enough at context.
I was referring to the things that inherit from OnlineLearner.
You are correct that Bayes isn't online or updatable as it stands. However,
that isn't necessary since all that Bayes depends on are counts which are
easily merged.
That will require a bit of spelunking to figure out where the counts are stored
and how to merge them.
