Skorohod Representation Theorem Via Disintegrations [PDF]

open access: yes
Let (µn : n >= 0) be Borel probabilities on a metric space S such that µn -> µ0 weakly. Say that Skorohod representation holds if, on some probability space, there are S-valued random variables Xn satisfying Xn - µn for all n and Xn -> X0 in probability.

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

open access: yesInternational Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Optimal transport on gas networks

open access: yesEuropean Journal of Applied Mathematics
Optimal transport tasks naturally arise in gas networks, which include a variety of constraints such as physical plausibility of the transport and the avoidance of extreme pressure fluctuations.

DOTmark – A Benchmark for Discrete Optimal Transport

open access: yesIEEE Access, 2017
The Wasserstein metric or earth mover's distance is a useful tool in statistics, computer science and engineering with many applications to biological or medical imaging, among others. Especially in the light of increasingly complex data, the computation

Surgical tagging of Atlantic mackerel (Scomber scombrus): electroanaesthesia and survival in captivity and the field

open access: yesJournal of Fish Biology, EarlyView.
Abstract Electroanaesthesia using electric fish handling gloves induced rapid and reversible sedation of Atlantic mackerel (Scomber scombrus) during surgical tagging without observable adverse effects on behaviour or tag retention. In the laboratory, survival analyses revealed that longer handling times and smaller body sizes significantly reduced ...

On the Stochastic Convergence of Representations Based on Wasserstein Metrics

open access: yesThe Annals of Probability, 1993
Under some regularity conditions an optimal coupling of two probability measures on a Hilbert space can be found in the form \((X,H(X))\) for some monotone function \(H\). It is shown that convergence of \(P_ n\) to \(P\) in distribution implies a.s. convergence of the optimal coupling functions \(H_ n\) in the finite-dimensional case. For the infinite-

Validation of machine learning based scenario generators

open access: yesJournal of Risk and Insurance, EarlyView.
Abstract Machine learning (ML) methods are becoming increasingly important for designing economic scenario generators for internal models. Validating data‐driven models requires different methods than validating classical, theory‐based models. We discuss two novel aspects of such validation: first, checking the multivariate distribution of risk factors,

Hybrid Proximal Policy Optimization—Wasserstein Generative Adversarial Network Framework for Hosting Capacity Optimization in Renewable-Integrated Power Systems

open access: yesEnergies
The rapid integration of distributed energy resources (DERs) such as photovoltaics (PV), wind turbines, and energy storage systems has transformed modern power systems, with hosting capacity optimization emerging as a critical challenge.

Bounding adapted Wasserstein metrics

open access: yes
The Wasserstein distance $\mathcal{W}_p$ is an important instance of an optimal transport cost. Its numerous mathematical properties as well as applications to various fields such as mathematical finance and statistics have been well studied in recent years.
