Irregularity of Distribution in Wasserstein Distance [PDF]

open access: yesJournal of Fourier Analysis and Applications, 2020
We study the non-uniformity of probability measures on the interval and the circle. On the interval, we identify the Wasserstein-$p$ distance with the classical $L^p$-discrepancy. We thereby derive sharp estimates in Wasserstein distances for the irregularity of distribution of sequences on the interval and the circle.

The Gromov–Wasserstein Distance: A Brief Overview

open access: yesAxioms, 2014
We recall the construction of the Gromov–Wasserstein distance and concentrate on quantitative aspects of the definition.

Basic statistics for probabilistic symbolic variables: a novel metric-based approach

open access: yes, 2013
In data mining, it is usually to describe a set of individuals using some summaries (means, standard deviations, histograms, confidence intervals) that generalize individual descriptions into a typology description. In this case, data can be described by

Scalar conservation laws seen as gradient flows: known results and new perspectives

open access: yesESAIM: Proceedings and Surveys, 2016
We review some results in the literature which attempted (only partly successfully) at linking the theory of scalar conservation laws with the Wasserstein gradient flow theory.

Towards Inverse Modeling of Landscapes Using the Wasserstein Distance

open access: yesGeophysical Research Letters, 2023
Extricating histories of uplift and erosion from landscapes is crucial for many branches of the Earth sciences. An objective way to calculate such histories is to identify calibrated models that minimize misfit between observations (e.g., topography) and

High-Dimensional Distributionally Robust Mean-Variance Efficient Portfolio Selection

open access: yesMathematics, 2023
This paper introduces a novel distributionally robust mean-variance portfolio estimator based on the projection robust Wasserstein (PRW) distance. This approach addresses the issue of increasing conservatism of portfolio allocation strategies due to high-

Universally Accurate or Specifically Inadequate? Stress‐Testing General Purpose Machine Learning Interatomic Potentials

open access: yesAdvanced Intelligent Discovery, EarlyView.
We investigate MACE‐MP‐0 and M3GNet, two general‐purpose machine learning potentials, in materials discovery and find that both generally yield reliable predictions. At the same time, both potentials show a bias towards overstabilizing high energy metastable states. We deduce a metric to quantify when these potentials are safe to use.

Wasserstein distance, Fourier series and applications [PDF]

open access: yesMonatshefte für Mathematik, 2021
We study the Wasserstein metric $W_p$, a notion of distance between two probability distributions, from the perspective of Fourier Analysis and discuss applications. In particular, we bound the Earth Mover Distance $W_1$ between the distribution of quadratic residues in a finite field $\mathbb{F}_p$ and uniform distribution by $\lesssim p^{-1/2}$ (the ...

First and second moments for self-similar couplings and Wasserstein distances

open access: yes, 2014
We study aspects of the Wasserstein distance in the context of self-similar measures. Computing this distance between two measures involves minimising certain moment integrals over the space of \emph{couplings}, which are measures on the product space ...

Inverse Design of Alloys via Generative Algorithms: Optimization and Diffusion within Learned Latent Space

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work presents a novel generative artificial intelligence (AI) framework for inverse alloy design through operations (optimization and diffusion) within learned compact latent space from variational autoencoder (VAE). The proposed work addresses challenges of limited data, nonuniqueness solutions, and high‐dimensional spaces.
