DOI: 10.1109/access.2025.3626026
Abstract: This paper proposes a novel lightweight non-negative variant of Parallel Factor Analysis 2 (PARAFAC2), coined as LNN-PARAFAC2, that simultaneously enforces non-negativity and reduces computational complexity. Non-negativity is imposed through the application of Lagrange multipliers with… read more here.
