Description
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.
