Vector has both dot() and cross() products. Are you looking at the
latest .diff?
I can easily move the vector package stuff back into matrix. It used to
be there and I moved it into its own package just to "organize" it
better. You are correct; however, that having them in the same package

That should be quite possible. K-means is an approximate implementation of

Ted noted an easy fix to my Excel use case that I wasn't aware of, so my
point is agreeably moot.
I concur that we ought to have additional Writable representations to
make intra-Hadoop transfers more streamlined. This is certainly *not*
too late to pursue. I would encourage you to propose a reco

Sounds good, I was mistakenly under the impression that this was
something you were going to donate...
These other implementations are also good for feeding the same input
and comparing results, I would imagine, although I don't think one for
one results comparison is necessary.

Hi Ankur,
I haven't had a chance to look at this yet, but I will most likely
after the 12 since I am swamped at work right now. I do want to get
it in Mahout, so if some other committer has the time before than,
that would be good too.

Ok, I'll look into it through the weekend -- there is a JIRA task for this (and

What about encouraging your students to submit their work at Mahout? Just a
naive thought of mine.
Those students I'm in charge of have their area of interest defined already --

I do see a few advantages of using static variables, actually -- I just wasn't
sure if it's contractual for Hadoop jobs to run in isolation from other jobs.
This is a refactoring rather than functionality improvement, so I'll leave the

The Excel scenario doesn't really convince me much, Jeff. For one thing, I don't
have Excel, but this is a minor issue, for another -- I don't think anyone will
actually import stuff that's supposed to be very large (that's why we do it in
Hadoop, don't we) into a spreadsheet.
