Researchers have published a new analysis of the Sinkhorn-Knopp (SK) algorithm, focusing on its local convergence properties. The study provides the first nonasymptotic local analysis that matches existing asymptotic Jacobian-based rates, demonstrating that SK can be a polynomial-time algorithm for doubly stochastic matrix scaling under specific connectivity conditions. The work also introduces accelerated variants and improves the complexity for dense matrices. AI
