%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: Wang Y. X. and Zhang Y. J. (2012).
