The kantorovich-rubinstein duality
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 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

WebDec 7, 2024 · Wasserstein GANs (WGANs), built upon the Kantorovich-Rubinstein (KR) duality of Wasserstein distance, is one of the most theoretically sound GAN models. However, in practice it does not always outperform other variants of GANs. This is mostly due to the imperfect implementation of the Lipschitz condition required by the KR duality. …
