"A fast randomized algorithm for the approximation of matrices,"
*Applied and Computational Harmonic Analysis*, 25 (3): 335-366, 2008: pdf.This article provides a generally preferable alternative to the classical pivoted "

*QR*" decomposition algorithms (such as Gram-Schmidt or Householder) for the low-rank approximation of arbitrary matrices. Constructing a low-rank approximation is the core step in computing several of the greatest singular values and corresponding singular vectors of a matrix. - Vladimir Rokhlin and Mark Tygert,
