Subject Re: How to find characteristics of the clusters with mahout?

I think you want to know why vectors are being assigned to any 
particular cluster.
Different clustering algorithms work in different way, so, I think some 
code will be needed for it.

The way I do it, is by taking a small set of vectors, and debug the 
clustering algorithm using their sequential version.
Its fast and makes things clear.

There are certain cluster evaluators also, which might help, but I don't 
know much about them, try to have a look at them also.
