Actually, I was confused between MLlib and Samsara, thanks Pat. I was already 
reading the documentation of MLlib. 

Cheers.

Re: Clustering options

[Pat Ferrel]

Mahout Samsara is more about rolling your own algo, though it has already 
implemented several as examples. If you want to build your own clustering you 
will find a lot of what you need in the R-like DSL. 

But if you want something already built you may want to look at Spark’s MLlib 
kmeans.

People often ask; what is the difference between Mahout and MLlib? MLlib is a 
collection of algos, Mahout is an optimized tensor math engine with many 
extensions and several algos. You can’t do the matrix A’B in MLlib because it’s 
not an algo, it’s a bit of math—a very useful bit.

[Dmitriy Lyubimov]

Xavier,
there are no exact equivalents in public domain to algorithms existed for
MR clustering as of yet. My understanding some of them are on the roadmap
though.

depending on the level of sophistication you require, some of them are very
easy to build though.

Clustering options

[FRANCISCO XAVIER SUMBA TORAL]

Hi,

Since clustering algorithms are deprecated in mahout samsara. How can I
make use of mahout to run a clustering algorithm. Basically, I use mahout
to cluster paper's keywords. I take a bunch of keywords and I cluster them
to find groups of related keywords. How can I update my code to mahout
samsara any suggestion?

Cheers

Kmeans clustering options

[Kate Ericson]

Hi all,

I just got the latest update to the first 6 chapters of Mahout In
Action, and it still says that '-r' is an option to k-means
clustering.  I'm working with 0.4, and I'm not seeing it as an option
off of -h.
I'm just looking for a sanity check - can you set the number of
reducers for k-means?

Thanks,

Kate

RE: Kmeans clustering options

[Jeff Eastman]

Only using a -Dmapred.reduce.tasks=n parameter. The explicit CLI argument was 
dropped in 0.4. Looks like the book has a typo.
