Limit distributions and sensitivity analysis for empirical entropic optimal transport on countable spaces

Authors Hundrieser S, Klatt M, Munk A Journal The Annals of Applied Probability Citation Ann. Appl. Probab. 34(1B): 1403-1468. Abstract For probability measures on countable spaces we derive distributional limits for empirical entropic optimal transport quantities. More precisely, we show that the empirical optimal transport plan weakly converges to a
