Such metric spaces are …
Webdistance, we resort to its Kantorovich-Rubinstein duality [13]: W(P r,P θ)=sup f L≤1 E x∼Pr [f(x)]−E x∼P θ [f(x)] For the vanilla GAN, the goal is to find the optimal configuration of the parameters φ of discriminator (f = D). When the discriminator is optimized, the maximized Wasserstein distance can be used as reward in the policy WebOct 24, 2024 · An easy consequence of Kantorovich-Rubinstein duality is the following: if is Lipschitz and , then where denotes the Wasserstein (or Earth Mover's) Distance. We prove …
WebKeywords— Duality, bi-Duality, Lipschitz Spaces, Compact Metric Spaces, Distance For a compact metric space (K,ρ), the predual of Lip(K,ρ) can be identified with the normed space M(K) of finite (signed) Borel measures on K equipped with the Kantorovich-Rubinstein norm, this is due to Kantorovich [20]. WebKantorovich-Rubinstein duality is considerably more general since it deals with two arbitrarymeasureswhile we require one of the measures to be the Lebesgue measure ν = dx. However, it is relatively easy to see that if both measures are allowed to be singular, one cannot get a better bound than k∇fkL∞: pick µ and ν to be two
WebThe Kantorovich-Rubinstein norm [5, x8.3] is closely related to the 1-Wasserstein distance and hence, to optimal transport problems. It will turn out that this ... ally, is similar to the Kantorovich-Rubinstein duality and shows the relation to optimal transport.
