我们建立了时间稳定性,w.r.t.迭代比例拟合过程的边缘,也称为Sinkhorn算法,用于解决熵正则化的最优运输问题。我们的结果是定量的,并表示在1-Wasserstein度量。作为推论,我们建立了薛定谔桥的定量稳定性结果。
We establish the uniform in time stability, w.r.t. the marginals, of the Iterative Proportional Fitting Procedure, also known as Sinkhorn algorithm, used to solve entropy-regularised Optimal Transport problems. Our result is quantitative and stated in terms of the 1-Wasserstein metric. As a corollary we establish a quantitative stability result for Schr\"odinger bridges.
