Uniform Statistical Convergence of Empirical Sinkhorn Potentials with Exponential and Polynomial Dependence on the Regularization Parameter
AI InsightThis study proves a non-asymptotic statistical rate of n^{-1/2} for empirical Sinkhorn potentials under uniform loss, with constants growing exponentially in 1/ε; it then identifies conditions preserving this rate with polynomial growth. This establishes a concrete convergence benchmark for entropic OT potential estimation.Key TakeawayEmpirical Sinkhorn potential convergence shifts from no clear bound to n^{-1/2} rate with explicit constant dependence.Why It MattersThis completes the statistical theory for entropic OT inference, affecting error analysis and credibility in high-dimensional applications, though constant issues remain.Who's Affected- AI ResearchersGet theoretical boundaries for Sinkhorn potential estimability, guiding algorithm design and error correction.
- DevelopersModels using OT distances can reference this rate for precision estimation, but exponential constants remain a practical concern.
