Summary:Many applications in computer vision, biomedical informatics, and graphics deal with data in the matrix or tensor form. Non-negative matrix and tensor factorization, which extract data-dependent non-negative basis functions, have been commonly applied for the analysis of such data for data compression, visualization, and detection of hidden information (factors). In this paper, we present a fast and flexible algorithm for sparse non-negative tensor factorization (SNTF) based on columnwise coordinate descent (CCD). Different from the traditional coordinate descent which updates one element at a time, CCD updates one column vector simultaneously. Our empirical results on higher-mode images, such as brain MRI images, gene expression images, and hyperspectral images show that the proposed algorithm is 1–2 orders of magnitude faster than several state-of-the-art algorithms. ► We present a columnwise coordinate descent (CCD) algorithm for sparse non-negative tensor factorization (SNTF). ► Different from the traditional coordinate descent, CCD updates one column vector simultaneously. ► The proposed algorithm is 1–2 orders of magnitude faster than several state-of-the-art algorithms.
