Classically, highly +accurate deterministic matrix algorithms are used for this task. However, the +emergence of large-scale data has severely challenged our computational +ability to analyze big data. The concept of randomness has been demonstrated +as an effective strategy to quickly produce approximate answers to familiar +problems such as the @dfn{singular value decomposition} (SVD). This package +provides several randomized matrix algorithms such as the randomized singular +value decomposition (@code{rsvd}), randomized principal component +analysis (@code{rpca}), randomized robust principal component +analysis (@code{rrpca}), randomized interpolative decomposition (@code{rid}), +and the randomized CUR decomposition (@code{rcur}). In addition several plot +functions are provided.") + (license license:gpl3+))) |
