On the sample complexity of entropic optimal transport

P Rigollet, AJ Stromme - The Annals of Statistics, 2025 - projecteuclid.org
We study the sample complexity of entropic optimal transport in high dimensions using
computationally efficient plug-in estimators. We significantly advance the state of the art by …

Tight stability bounds for entropic Brenier maps

V Divol, J Niles-Weed, AA Pooladian - arxiv preprint arxiv:2404.02855, 2024 - arxiv.org
Entropic Brenier maps are regularized analogues of Brenier maps (optimal transport maps)
which converge to Brenier maps as the regularization parameter shrinks. In this work, we …
