softImpute_1.0 uploaded to CRAN
..., to avoid overly expensive operations.
* warm starts can be used to move from one solution to a new solution with a different value for the nuclear-norm regularization parameter lambda (and/or a different rank)
* with lambda=0 and a specified rank, one automatically gets an implementation of "hardImpute" - iterative svd imputation
* softImpute has an option "type" which can be "svd" or "als" (alternating least squares), for specifying which of the two approaches above should be used.
*included in the package is svd.als, an efficient rank-restricted svd algorithm...
