> Since alternative flow using Cholesky decomposition is extremely easy to add
> to existing computations of BB', I am thinking of just adding an option that
> chooses between B-pipeline with QR step and B-pipeline with Y'Y-Cholesky
> step.
> Ongoing work and some initial code (Y'Y step) is here
> https://github.com/dlyubimov/mahout-commits/tree/MAHOUT-797.
> I also want to fix what's left unfixed in MAHOUT-638.
