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 whose marginals are u and v on the first and second factors respectively. If U and V are the respective CDFs of u and v, this distance also equals to: WebSep 2, 2024 · Over the past ten years, optimal transport has become a fundamental tool in statistics and machine learning: the Wasserstein metric provides a new notion of distance …
