svd_lapack_driver{“gesdd”, “gesvd”}, default=”gesdd”. Whether to use the more efficient divide-and-conquer approach ( "gesdd") or more general rectangular approach ( "gesvd") to compute the SVD of the matrix B, which is the projection of M into a low dimensional subspace, as described in [1]. New in version 1.2. TīmeklisRandomized partial SVD. Source: R/randomSVD.R. An algorithm for partial SVD (or PCA) of a Filebacked Big Matrix based on the algorithm in RSpectra (by Yixuan Qiu and Jiali Mei). This algorithm is linear in time in all dimensions and is very memory-efficient. Thus, it can be used on very large big.matrices.
