New Perspectives on Regularization and Computation in Optimal Transport-Based Distributionally Robust Optimization
Daniel Kuhn, Florian Dörfler, Soroosh Shafieezadeh Abadeh
We study optimal transport-based distributionally robust optimization problems where a fictitious adversary, often envisioned as nature, can choose the distribution of the uncertain problem parameters by reshaping a prescribed reference distribution at a f ...
2023Equilibria in Network Constrained Energy Markets
We study an energy market composed of producers who compete to supply energy to different markets and want to maximize their profits. The energy market is modeled by a graph representing a constrained power network where nodes represent the markets and lin ...
Elsevier2023Modelisation of fiber reinforced DEAs
The aim of this "Face Reconstruction" project is to enable people with paralysis in one half of their face to recover facial expressions. To do this, we’ll replace the paralyzed muscle with an DEA which we’ll connect to the nerve on the other side of the f ...
2023Reusability Assessment of Obsolete Reinforced Concrete Structural Components
Corentin Jean Dominique Fivet, Maléna Bastien Masse, Célia Marine Küpfer, Julie Rachel Devènes
The production of concrete, the most widely used construction material, detrimentally affects the environment. Obsolete reinforced concrete (RC) load-bearing structures, even when still in good condition, are today prematurely crushed and landfilled or rec ...
Springer2023What about Diamond Open Access?
Diamond Open Access is a scholarly publishing model characterized by journals and platforms that do not impose fees nor on authors neither on readers. These journals typically operate as community-driven, academically-led, and academically-owned initiative ...
2023Beyond Time-Average Convergence: Near-Optimal Uncoupled Online Learning via Clairvoyant Multiplicative Weights Update
Efstratios Panteleimon Skoulakis
In this paper we provide a novel and simple algorithm, Clairvoyant Multiplicative Weights Updates (CMWU), for convergence to \textit{Coarse Correlated Equilibria} (CCE) in general games. CMWU effectively corresponds to the standard MWU algorithm but where ...
2022Finite element method–discrete element method bridging coupling for the modeling of gouge
Jean-François Molinari, Guillaume Anciaux, Antonio Joaquin Garcia Suarez, Manon Eugénie Voisin--Leprince
We discuss the multiscale modeling of a granular material trapped between continuum elastic domains. The amorphous granular region, usually termed “gouge,” is under high confinement pressure, to represent the loading of faults at depth. We model the granul ...
2022Principal Portfolios
We propose a new asset pricing framework in which all securities' signals predict each individual return. While the literature focuses on securities' own-signal predictability, assuming equal strength across securities, our framework includes cross-predict ...
WILEY2022Mixed Nash Equilibria in the Adversarial Examples Game
This paper tackles the problem of adversarial examples from a game theoretic point of view. We study the open question of the existence of mixed Nash equilibria in the zero-sum game formed by the attacker and the classifier. While previous works usually al ...
2021A Simulation-Based Heuristic to Find Approximate Equilibria with Disaggregate Demand Models
Michel Bierlaire, Virginie Janine Camille Lurkin, Stefano Bortolomiol
Oligopolistic competition occurs in various transportation markets. In this paper, we introduce a framework to find approximate equilibrium solutions of oligopolistic markets in which demand is modeled at the disaggregate level using discrete choice models ...
