Web26 Feb 2024 · When the distance matrix is based on a valid distance function, the minimum cost is known as the Wasserstein distance. There is a large body of work regarding the solution of this problem and its extensions to continuous probability distributions. WebThe first Wasserstein distance between the distributions u and v is: l 1 ( u, v) = inf π ∈ Γ ( u, v) ∫ R × R x − y d π ( x, y) where Γ ( u, v) is the set of (probability) distributions on R × R … chew resistant plush dog toys
