So, I'm messing around with a clustering problem where I want to move
items from cluster to cluster and maintain centroids. Lazy person that
I am, I am using the Canopy class. But it looks to me like I have to
recreate the Canopy when I pull something out. Have I missed anything?
Sean, Jack, the PR is an excellent idea, I was not even thinking about it,
but a tweaked version of the PageRank algorithm can absolutely work for
this, and is relatively easy to implement.
Ted, straight question, thank you. You are right, I'm not working for a
washing powder company nor a laundry
And further linear Markov chains can be expressed as matrix products which
can be computed efficiently using SVD's.
Zoltan, is this literally the problem that you are working on? Or is this
a shadow of the problem that you are interested in?

Hi everyone!
I'm trying to use DistributedRowMatrix in my class code but I'm getting the
same error all the time: "FileNotFoundException"
I have put a file in my hdfs directory under /user/hduser/diffuse. And I run
the progam with "diffuse" as input and output directory. The code looks like:
It may further help to note that PageRank is a special case of a Markov
chain, and this washing system may well be described by a Markov chain
model.

Hi,
I posted this on stack overflow, but I've been informed that the mailing
list is the appropriate forum to ask questions like this.
What I need is actually just a hint where I can start, as I'm not sure
which direction to go. Although this is not a classic machine learning
problem, AFAIK Mahou
