Title: Regularized Non-Negative Matrix Factorization
BugReports: https://github.com/shabbychef/rnnmf/issues
Description: A proof of concept implementation of regularized
        non-negative matrix factorization optimization. A non-negative
        matrix factorization factors non-negative matrix Y
        approximately as L R, for non-negative matrices L and R of
        reduced rank. This package supports such factorizations with
        weighted objective and regularization penalties. Allowable
        regularization penalties include L1 and L2 penalties on L and
        R, as well as non-orthogonality penalties. This package
        provides multiplicative update algorithms, which are a
        modification of the algorithm of Lee and Seung (2001)
        <http://papers.nips.cc/paper/1861-algorithms-for-non-negative-matrix-factorization.pdf>,
        as well as an additive update derived from that multiplicative
        update.  See also Pav (2024) <doi:10.48550/arXiv.2410.22698>.
