Web12 Apr 2024 · SciPy is an open-source scientific computing library for the Python programming language. Since its initial release in 2001, SciPy has become a de facto standard for leveraging scientific ... WebLet us define the smoothed 2-Wasserstein distance: W 2, e ( p, q) = inf π ∈ Π ( p, q) ∑ i, j π i, j d 2 ( i, j) − λ E ( π) The benefit of the entropy term is that the resulting function is strongly concave [Peyre 2024] and that we can therefore more easily find a solution.

WebIn mathematics, the Wasserstein distance or Kantorovich – Rubinstein metric is a distance function defined between probability distributions on a given metric space . It is named … WebTo be more precise, consider as a canonical example the process of using the Wasserstein distance in the Wasserstein GAN application [1]. The general goal is to fine tune a neural network to generate synthetic data that is similar in some sense to a target data set. The network is trained in order to minimize the Wasserstein distance.

See the documentation. Copyright (C) 2024-2024 Patrick T. Komiske III Web26 Dec 2024 · In particular, the Wasserstein distance is the Euclidean distance on the half-plane H = { ( μ, σ) σ > 0 }. On the other hand, the Fisher metric is hyperbolic, with metric d s 2 = 1 σ 2 ( d μ 2 + 2 d σ 2). As a result, when the variance is large enough, the distance in the Fisher-Rao metric will be smaller than in the Wasserstein metric.
