MapReduce SSVD: provide alternative B-pipeline per B=R' ^{-1} Y'A
-----------------------------------------------------------------
Key: MAHOUT-797
URL: https://issues.apache.org/jira/browse/MAHOUT-797
Project: Mahout
Issue Type: Improvement
Reporter: Dmitriy Lyubimov
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.
I also want to fix what's left unfixed in MAHOUT-638.
