Ted Dunning commented on MAHOUT-550:
------------------------------------
This seems not nearly as good as the implementation that is part of Dmitriy's
random projection SVD.
In particular, there is no need to cache the results. It is better to compute
them on the fly every time.
Also, most of these tests are redundant relative to the tests that should be
inherited from the standard matrix tests.
I don't think this is ready for inclusion.
