Szymon Chojnacki updated MAHOUT-588:
------------------------------------
Attachment: TamingSubsetMapper.java
TamingSubset.java
Two classes:
TamingSubset.java
TamingSubsetMapper.java
can be used to extract a subset of vectors from e.g. a /tfidf-vectors/
directory. It is useful to get some results when clustering runs too long with
available resources (or throws heap error).
Usage:
TamingSubset [inputPath] [outputPath] [percentage to retain (0,100)]
> 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.
