WebAn Optimal Transportation (OT) View of Generative Adversarial Networks (GANs) - Part 1 David Xianfeng Gu SUNY Stony Brook Generative Adversarial Net (GAN) is a powerful machine learning model, and becomes extremely successful recently. The generator and the discriminator in a GAN model competes each other and reaches the Nash equilibrium. WebOptimal Transport Distance Between r and c Given a d×dcost matrix M, the cost of mapping r to c using a transport matrix (or joint probability) P can be quantified as hP,M i. The problem defined in Equation (1) dM(r,c) := min P∈U(r,c) hP,M i. (1) is called an optimal transport (OT) problem between r and c given cost M. An optimal table P⋆

Brenier Optimal Transportation Theorem/Alexandrov Convex Polytope Theorem The algorithm is based on the classical Brenier optimal transportation theorem, which claims that the optimal transportation map is the gradient … WebJun 15, 2024 · We introduce COT-GAN, an adversarial algorithm to train implicit generative models optimized for producing sequential data. The loss function of this algorithm is formulated using ideas from Causal Optimal Transport (COT), which combines classic optimal transport methods with an additional temporal causality constraint.

Web2.3 Optimal transport Another important background in this paper is optimal transport. Suppose there are two probability densities, p(x) and q(y) where x;y 2X. Let us consider the cost for transporting one unit of mass from x ˘p to y ˘q. The optimal cost is called Wasserstein distance.
