Earth mover’s distance as a measure of CP violation

open access: yesJournal of High Energy Physics, 2023
We introduce a new unbinned two sample test statistic sensitive to CP violation utilizing the optimal transport plan associated with the Wasserstein (earth mover’s) distance.

Multimedia Analysis and Fusion via Wasserstein Barycenter

open access: yesInternational Journal of Networked and Distributed Computing (IJNDC), 2020
Optimal transport distance, otherwise known as Wasserstein distance, recently has attracted attention in music signal processing and machine learning as powerful discrepancy measures for probability distributions.

Fused Gromov-Wasserstein Distance for Structured Objects

open access: yesAlgorithms, 2020
Optimal transport theory has recently found many applications in machine learning thanks to its capacity to meaningfully compare various machine learning objects that are viewed as distributions.

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 linearization of quadratic Wasserstein distance

open access: yesCoRR, 2022
This paper studies the problem of computing a linear approximation of quadratic Wasserstein distance $W_2$. In particular, we compute an approximation of the negative homogeneous weighted Sobolev norm whose connection to Wasserstein distance follows from a classic linearization of a general Monge-Ampére equation. Our contribution is threefold.

Kernel Wasserstein Distance

open access: yesCoRR, 2019
The Wasserstein distance is a powerful metric based on the theory of optimal transport. It gives a natural measure of the distance between two distributions with a wide range of applications. In contrast to a number of the common divergences on distributions such as Kullback-Leibler or Jensen-Shannon, it is (weakly) continuous, and thus ideal for ...

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

Matricial Wasserstein-1 Distance [PDF]

open access: yesIEEE Control Systems Letters, 2017
In this note, we propose an extension of the Wasserstein 1-metric ($W_1$) for matrix probability densities, matrix-valued density measures, and an unbalanced interpretation of mass transport. The key is using duality theory, in particular, a "dual of the dual" formulation of $W_1$.

Graph Diffusion Wasserstein Distances [PDF]

open access: yes, 2021
Optimal Transport (OT) for structured data has received much attention in the machine learning community, especially for addressing graph classification or graph transfer learning tasks. In this paper, we present the Diffusion Wasserstein (DW) distance, as a generalization of the standard Wasserstein distance to undirected and connected graphs where ...

Subspace Robust Wasserstein Distances

open access: yesCoRR, 2019
Making sense of Wasserstein distances between discrete measures in high-dimensional settings remains a challenge. Recent work has advocated a two-step approach to improve robustness and facilitate the computation of optimal transport, using for instance projections on random real lines, or a preliminary quantization of the measures to reduce the size ...
