Optimal transport ot layer
WebSep 24, 2024 · Optimal transport gives us a way to quantify the similarity between two probability density functions in terms of the lowest total cost incurred by completely shoveling one pile into the shape and location of the other. Formally, the general optimal transport problem between two probability distributions and over a space is defined as:

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.
