Hi,
I am new to mahout.
i have text data in fomat as
Id,age,income,perwt,sex,city,product
1,23,2200,40,2,Boston,product #1
I want to perform kmeans clustering based on 2 feilds that is age and
income.And i also want perform in specific number of clusters.
I have already performed clustering by
How are u converting your data to sequencefile?
If you are not sure check this link:
http://stackoverflow.com/questions/13663567/mahout-csv-to-vector-and-running-the-program
Are you getting any clusteredpoints after running k-means?
It would help if you could list the commands you had
Thanks for your response
yes,I get clustered points after running Kmeans. I have done clustering
sucessfully with 20newsdata and reuters data.Clusterdump also works
properly with above stated examples.
Now,
i have text data in fomat as
Id,age,income,perwt,sex,city,product

Yes. You definitely need custom code for this.
You also need to think about your data and why you want clusters.
What does age mean to a cluster? Are

Ok, so i was fairly easily able to build some DSL for our matrix
manipulation (similar to breeze) in scala:
inline matrix or vector:
val a = dense((1, 2, 3), (3, 4, 5))
val b:Vector = (1,2,3)
block views and assignments (element/row/vector/block/block of row or
vector)
a(::, 0)
a(1, ::)
a(0
Dmitriy,
This is very pretty.

Yeah, I'm totally on board with a pretty scala DSL on top of some of our
stuff.
In particular, I've been experimenting with with wrapping the
DistributedRowMatrix
in a scalding wrapper, so we can do things like
val matrixAsTypedPipe =
DistributedRowMatrixPipe(new DistributedRowMatrix(numRows,
That looks great Dmitry!
The thing about Breeze that drives the complexity in it is partly
specialization for Float, Double and Int matrices, and partly getting the
syntax to just work for all combinations of matrix types and operands etc.
mostly it does just work but occasionally not.
Hi,
I am Samiran. I participated in 3 day local workshop at ICFOSS (
http://community.apache.org/mentoringprogramme-icfoss-pilot.html). I am
looking forward to contribute to Mahout project.

I think that contrib modules would be very interesting. Specifically, good
Scala DSL, pig integration and so on.

You're right on that - so far doubles is all I've needed and all I can
currently see needing.
I'll take a look at your project and see how easy it is to integrate with my
Spark ALS and other code - syntax wise it looks almost the same so swapping out
the linear algebra backend would be
Well one fundamental step to get there in Mahout realm, the way i see it,
is to create DSLs for Mahout's DRMs in spark. That's actually one of the
other reasons i chose not to follow Breeze. When we unwind Mahout DRM's, we
may see sparse or dense slices there with named vectors. To translate that

Not sure, but if we are having it I think we should focus on what's left for

Can someone w/ more Hadoop experience look at this? We are getting:

Never mind the noise here, I misread this!
Still, we have some error going on w/ random failures.
