Gromov–Wasserstein distances between Gaussian distributions

open access: yesJournal of Applied Probability, 2022
AbstractGromov–Wasserstein distances were proposed a few years ago to compare distributions which do not lie in the same space. In particular, they offer an interesting alternative to the Wasserstein distances for comparing probability measures living on Euclidean spaces of different dimensions. We focus on the Gromov–Wasserstein distance with a ground

Shape Analysis with Hyperbolic Wasserstein Distance. [PDF]

open access: yesProc IEEE Comput Soc Conf Comput Vis Pattern Recognit, 2016
Shape space is an active research field in computer vision study. The shape distance defined in a shape space may provide a simple and refined index to represent a unique shape. Wasserstein distance defines a Riemannian metric for the Wasserstein space. It intrinsically measures the similarities between shapes and is robust to image noise.

Free complete Wasserstein algebras [PDF]

open access: yesLogical Methods in Computer Science, 2018
We present an algebraic account of the Wasserstein distances $W_p$ on complete metric spaces, for $p \geq 1$. This is part of a program of a quantitative algebraic theory of effects in programming languages.

On a Linear Gromov–Wasserstein Distance

open access: yesIEEE Transactions on Image Processing, 2022
Gromov-Wasserstein distances are generalization of Wasserstein distances, which are invariant under distance preserving transformations. Although a simplified version of optimal transport in Wasserstein spaces, called linear optimal transport (LOT), was successfully used in practice, there does not exist a notion of linear Gromov-Wasserstein distances ...

Federated Wasserstein Distance

open access: yes, 2023
We introduce a principled way of computing the Wasserstein distance between two distributions in a federated manner. Namely, we show how to estimate the Wasserstein distance between two samples stored and kept on different devices/clients whilst a central entity/server orchestrates the computations (again, without having access to the samples).

Generalized Wasserstein distance and its application to transport equations with source [PDF]

open access: yes, 2012
In this article, we generalize the Wasserstein distance to measures with different masses. We study the properties of such distance. In particular, we show that it metrizes weak convergence for tight sequences.

The “Unreasonable” Effectiveness of the Wasserstein Distance in Analyzing Key Performance Indicators of a Network of Stores

open access: yesBig Data and Cognitive Computing, 2022
Large retail companies routinely gather huge amounts of customer data, which are to be analyzed at a low granularity. To enable this analysis, several Key Performance Indicators (KPIs), acquired for each customer through different channels are associated

Alignment of density maps in Wasserstein distance. [PDF]

open access: yesBiol Imaging
Abstract In this article, we propose an algorithm for aligning three-dimensional objects when represented as density maps, motivated by applications in cryogenic electron microscopy. The algorithm is based on minimizing the 1-Wasserstein distance between the density maps after a rigid transformation.

Unified topological inference for brain networks in temporal lobe epilepsy using the Wasserstein distance

open access: yesNeuroImage, 2023
Persistent homology offers a powerful tool for extracting hidden topological signals from brain networks. It captures the evolution of topological structures across multiple scales, known as filtrations, thereby revealing topological features that ...

Tanaka Theorem for Inelastic Maxwell Models [PDF]

open access: yes, 2006
We show that the Euclidean Wasserstein distance is contractive for inelastic homogeneous Boltzmann kinetic equations in the Maxwellian approximation and its associated Kac-like caricature.
