摘要: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 centered Gaussian process and that the empirical entropic optimal transport value is asymptotically normal. The results are valid for a large class of cost functions and generalize distributional limits for empirical entropic optimal transport quantities on finite spaces. Our pro...

摘要:Consider the Monge-Kantorovich problem of transporting densities rho(0) to rho(1) on R-d with a strictly convex cost function. A popular regularization of the problem is the one-parameter family called the entropic cost problem. The entropic cost K-h, h> 0, is significantly faster to compute and hK(h) is known to converge to the optimal transport cost as h goes to zero. We are interested in the rate of convergence. We show that the difference between K-h and 1/ h times the optimal cost of tran...
