Webunbalanced optimal transport to million-scale datasets. 1 Introduction The optimal transport (OT) distance is an effective tool to compare measures and is used in a variety of fields. The applications of OT include image processing [45, 50, 23], natural language processing [38, 52], biology [57, 43, 26], and generative models [4, 54]. WebThe Monge formulation of optimal transport restricts itself to transportation between two uniform discrete densities whose support has the same size n n. In particular, it seeks a mapping from one density α α to another β β, where. α = n ∑ i=1aiδxi, β = n ∑ j=1bjδyj α = ∑ i = 1 n a i δ x i, β = ∑ j = 1 n b j δ y j.
