Near-Universal Multiplicative Updates for Nonnegative Einsum Factorization arXiv:2602.02759v1 Announce Type: new Abstract: Despite the ubiquity of multiway data across scientific domains, there are few user-friendly tools that fit tailored nonnegative tensor factorizations. Researchers may use gradient-based automatic differentiation (which often struggles in nonnegative settings), choose between a limited set of methods with mature implementations, or…
