WebApr 24, 2024 · This takes advantage of the fact that 1-dimensional Wassersteins are extremely efficient to compute, and defines a distance on d -dimesinonal distributions by taking the average of the Wasserstein distance between random one-dimensional projections of the data. WebSep 17, 2024 · Wasserstein distance is a meaningful metric, i.e, it converges to 0 as the distributions get close to each other and diverges as they get farther away. Wasserstein Distance as objective function is more stable than using JS divergence. The mode collapse problem is also mitigated when using Wasserstein distance as the objective function. claw graphic
