Reinis,
The documentation has several Jira¹s open - with one with my name on it.
Fortunately, the canopy cluster technology has a good page (as well as
some outdated pages).
Please see this link for your question:
http://mahout.apache.org/users/clustering/canopy-clustering.html
as I believe that it is well written.
To directly answer your question:
Remember that T1 > T2 and points within T2 are added to the cluster and
removed from the "input set", while points within T1 are added to the
cluster but NOT removed from the ³input set" (and therefore may be added
to another cluster later in the process).
