Pytorch wasserstein distance
WebSliced Wasserstein barycenter and gradient flow with PyTorch ===== In this exemple we use the pytorch backend to optimize the sliced Wasserstein: loss between two empirical distributions [31]. In the first example one we perform a: gradient flow on the support of a distribution that minimize the sliced: Wassersein distance as poposed in [36]. WebApr 1, 2024 · Eq.(1): Wasserstein distance. Where .,. is the Frobenius product and E(α, β) the set of constraints.The Wasserstein distance has to be computed between the full measures α and β.Unfortunately, it has a cubical complexity in the number of data O(n^3), making it non suitable for Big Data applications.Variants of OT problem came out such as the …

It is based on a closed form expression for 1D measures of the Gromov-Wasserstein distance (GW) [2] that allows a sliced version of GW akin to the Sliced Wasserstein distance.
WebMar 12, 2024 · After I train the critic (lets say 5 times) If I estimate the Wasserstein distance between real and fake samples like (critic (real) - critic (fake)) it gives me a positive real number. After few epochs the Wasserstein distance between becomes negative and goes on decreasing. So, my question is basically what does this positive distance imply ?
