Linear algebra routines for Scalding.
Right now contains Tall-Skinny QR Factorization, based on the paper by Constantine and Gleich:
The direct Q calculation is from a preprint by Benson, Demmel and Gleich:
SVD via random projection based on the approach of Halko, Martinsson and Tropp:
Also investigating to see if there is a good parallel NMF algorithm suitable for Hadoop.
