------------------------------------
I guess, I will correct the first point Jeff mentioned on list.
> One possible alternative might be to add a sort of iterator mechanism in the

+1 to that. Maybe we could add that functionality after the patch is comitted,
enhance the vector implementation after that? There were a few other points
that Jeff mentioned. I would rather like to keep this patch focussed on the
k-Means and Canopy classes and rather not touch the matrix stuff in it.
The alternative would be to wait with the patch until the proposed
functionality is available in the matrix stuff.

> Issue Type: Task
> Components: Clustering
> Affects Versions: 0.1
> Reporter: Jeff Eastman

>
> Canopy and KMeans clustering implementations use Float[] representations
> instead of the new Vector package. They need to be migrated and the Vector
> package may need some enhancement to support the notion of payloads. This
> would be a good project for somebody new to the project who wants to get
> involved. If somebody wants to implement this, just assign the issue to
> yourself and I will hold off doing it myself.
