Abstract

Non-negative matrix factorization (NMF) and non-negative tensor factorization (NTF) have attracted much attention and have been successfully applied to numerous data analysis problems where the elements of the data are necessarily non-negative such as chemical concentrations, spectrometry signal intensities, and digital image pixels. Especially, Andersson and Bro's PARAFAC algorithm with non-negativity constraints (AB-PARAFAC-NC) provided the state-of-the-art NTF algorithm, which uses Bro and de Jong's non-negativity-constrained least squares with single right hand side (NLS/S-RHS). However, solving an NLS with multiple right hand sides (NLS/M-RHS) problem by multiple NLS/S-RHS problems is not recommended due to hidden redundant computation. In this paper, we propose an NTF algorithm based on alternating large-scale non-negativity-constrained least squares (NTF/ANLS) using NLS/M-RHS. In addition, we introduce an algorithm for the regularized NTF based on ANLS (RNTF/ANLS). Our experiments illustrate that our NTF algorithms outperform AB-PARAFAC-NC in terms of computing speed on several data sets we tested.
