Robustness of Minimum-Volume Nonnegative Matrix Factorization under an Expanded Sufficiently Scattered Condition
Giovanni Barbarino, Nicolas Gillis, Subhayan Saha
Minimum-volume nonnegative matrix factorization (min-vol NMF) has been used successfully in many applications, such as hyperspectral imaging, chemical kinetics, spectroscopy, topic…
Identifiability of Nonnegative Tucker Decompositions -- Part I: Theory
Subhayan Saha, Giovanni Barbarino, Nicolas Gillis
Tensor decompositions have become a central tool in data science, with applications in areas such as data analysis, signal processing, and machine learning. A key property of many…
Computing cone-constrained singular values of matrices
Giovanni Barbarino, Nicolas Gillis, David Sossa
This paper deals with the numerical computation of the least singular value of a rectangular matrix relative to a pair of closed convex cones , which is defined as the o…
