Beyond entropic regularization: Debiased Gaussian estimators for discrete optimal transport and general linear programs
Shuyu Liu, Florentina Bunea, Jonathan Niles-Weed
This work proposes new estimators for discrete optimal transport plans that enjoy Gaussian limits centered at the true solution. This behavior stands in stark contrast with the per…
