Szymon Chojnacki updated MAHOUT-588:
------------------------------------
Attachment: mahout-588_distribution.pdf
PDF file:
mahout-588_distribution.pdf
contains an analysis of the relationship between the minCount cutoff set in
seq2sparse and maximum cardinality of tfidf-vectors or centroids.
> Benchmark Mahout's clustering performance on EC2 and publish the results

> For Taming Text, I've commissioned some benchmarking work on Mahout's
> clustering algorithms. I've asked the two doing the project to do all the
> work in the open here. The goal is to use a publicly reusable dataset (for
> now, the ASF mail archives, assuming it is big enough) and run on EC2 and
> make all resources available so others can reproduce/improve.
> I'd like to add the setup code to utils (although it could possibly be done
> as a Vectorizer) and the publication of the results will be put up on the
> Wiki as well as in the book. This issue is to track the patches, etc.
