2019 arXiv   pre-print
We present a software package called PLANC (Parallel Low Rank Approximation with Non-negativity Constraints), which implements our solution and allows for extension in terms of data (dense or sparse, matrices  ...  to compute the low-rank approximation.  ...  In this paper, we present an open-source software package called Parallel Low-Rank Approximation with Non-negativity Constraints (PLANC) that currently includes six algorithmic options, and we describe  ...

2019 arXiv   pre-print
Due to the compute-intensive nature of applications that must perform repeated NMF, several parallel implementations have been developed in the past.  ...  In this paper, we devise a parallel NMF algorithm based on the HALS (Hierarchical Alternating Least Squares) scheme that incorporates algorithmic transformations to enhance data locality.  ...  D Number of columns in A and H K Low rank Table 2 : 2 Previous studies on parallelization of NMF Author Machine Platform Algorithm Battenberg et al.
