Optimal transport gan
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⋆ 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. Throughout this paper, we
