Description: Nonnegative matrix factorization (NMF) is a technique to
        factorize a matrix with nonnegative values into the product of
        two matrices. Covariates are also allowed. Parallel computing
        is an option to enhance the speed and high-dimensional and
        large scale (and/or sparse) data are allowed. Relevant papers
        include: Sevinc V., Kontemeniotis N., Perdikis T. and Tsagris
        M. (2026). Non-negative matrix factorization using the R
        package nnmf <doi:10.48550/arXiv.2607.20084>, Wang Y. X. and
