Cross-Validation for the SVD (Bi-Cross-Validation)

CRAN Package

Methods for choosing the rank of an SVD (singular value decomposition) approximation via cross validation. The package provides both Gabriel-style "block" holdouts and Wold-style "speckled" holdouts. It also includes an implementation of the SVDImpute algorithm. For more information about Bi-cross-validation, see Owen & Perry's 2009 AoAS article (doi:10.48550/arXiv.0908.2062) and Perry's 2009 PhD thesis (doi:10.48550/arXiv.0909.3052).
