LNN-PARAFAC2: Lightweight Non-Negative PARAFAC2 With Applications in Cross-Lingual Document Classification

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 multiplicati...
