Substantive Agency and Computational Non-Anticipability: An Axiomatic Route to a Conditional Separation of P and N P
Jérome Clech
This paper characterises substantive agency and identifies the additional bridges under which it has a standard complexity-theoretic consequence: conditionally, P __ = N P . The co…
Computational free will as global selection: from sheaf-theoretic gluing to a conditional separation of P and NP
Jerome Clech
We formalise computational free will by separating locally constrained admissibility from the selection of one global continuation. Global sections of a finite choice presheaf form…
Signed Networks: theory, methods, and applications
Fernando Diaz-Diaz, Elena Candellone, Miguel A. Gonzalez-Casado +4
Signed networks provide a principled framework for representing systems in which interactions are not merely present or absent but qualitatively distinct: friendly or antagonistic,…
No Such Thing as Free Brain Time: For a Pigouvian Tax on Attention Capture
Hamza Belgroun, Franck Michel, Fabien Gandon
In our age of digital platforms, human attention has become a scarce and highly valuable resource, rivalrous, tradable, and increasingly subject to market dynamics. This article ex…
Web Crawler Restrictions, AI Training Datasets \& Political Biases
Paul Bouchaud, Pedro Ramaciotti
Large language models rely on web-scraped text for training; concurrently, content creators are increasingly blocking AI crawlers to retain control over their data. We analyze craw…
Perceptual Noise-Masking with Music through Deep Spectral Envelope Shaping
Clémentine Berger, Roland Badeau, Slim Essid
People often listen to music in noisy environments, seeking to isolate themselves from ambient sounds. Indeed, a music signal can mask some of the noise's frequency components due…
Getting There and Getting In: How Mobility and Sorting Keep Women out of Top Startup Accelerators
Chuan Chen, Michele Fioretti, Junnan He +1
Startup accelerators are a leading gateway to venture capital, but top programs often require founders to relocate to a venture hub. From a hand-collected census of U.S. accelerato…
Expressing One's Identity Online: Left-Right and cross EU-country variation in self-representation in social media
Carlo Romano Marcello Alessandro Santagiustina, Jean-Philippe Cointet, Pedro Ramaciotti Morales
We examine how social media users from eight European Union (EU) member states express their socio-political identities, focusing on users' online self-presentation and group ident…
An Incremental Clustering Baseline for Event Detection on Twitter
Marjolaine Ray, Qi Wang, Frédérique Mélanie-Becquet +2
Event detection in text streams is a crucial task for the analysis of online media and social networks. One of the current challenges in this field is establishing a performance st…
Capacity, Technology Portfolios, and the Paradox of Concentration
Michele Fioretti, Junnan He, Jorge Tamayo
Does limiting the largest firm's capacity always lower prices? We model firms competing in supply schedules with multiple technologies, each with constant marginal cost up to capac…
Towards Transparency: Exploring LLM Trainings Datasets through Visual Topic Modeling and Semantic Frame
Charles de Dampierre, Andrei Mogoutov, Nicolas Baumard
LLMs are now responsible for making many decisions on behalf of humans: from answering questions to classifying things, they have become an important part of everyday life. While c…
The Neutrality Fallacy: When Algorithmic Fairness Interventions are (Not) Positive Action
Hilde Weerts, Raphaële Xenidis, Fabien Tarissan +2
Various metrics and interventions have been developed to identify and mitigate unfair outputs of machine learning systems. While individuals and organizations have an obligation to…
Impacts of electric carsharing on a power sector with variable renewables
Adeline Guéret, Wolf-Peter Schill, Carlos Gaete-Morales
Electrifying the car fleet is a major strategy for mitigating emissions in the transport sector. As electrification cannot solve all negative externalities associated with cars, re…
The matching problem with linear transfers is equivalent to a hide-and-seek game
Alfred Galichon, Antoine Jacquet
Matching problems with linearly transferable utility (LTU) generalize the well-studied transferable utility (TU) case by relaxing the assumption that utility is transferred one-for…
Modelling pyro-convection phenomenon during a mega-fire event in Portugal
Cátia Campos, Flavio Tiago Couto, Jean-Baptiste Filippi +2
The present study contributes to an increased understanding of pyro-convection phenomena by using a fire-atmosphere coupled simulation, and investigates in detail the large-scale m…
Algorithmic Unfairness through the Lens of EU Non-Discrimination Law: Or Why the Law is not a Decision Tree
Hilde Weerts, Raphaële Xenidis, Fabien Tarissan +2
Concerns regarding unfairness and discrimination in the context of artificial intelligence (AI) systems have recently received increased attention from both legal and computer scie…
Evaluating end-to-end entity linking on domain-specific knowledge bases: Learning about ancient technologies from museum collections
Sebastian Cadavid-Sanchez, Khalil Kacem, Rafael Aparecido Martins Frade +4
To study social, economic, and historical questions, researchers in the social sciences and humanities have started to use increasingly large unstructured textual datasets. While r…
Game theory: An appropriate tool for strategic analysis ?
Marc-Olivier Boisset, Jean Langlois-Berthelot, Didier Bazalgette
According to one of its founders, game theory would soon be a little over a hundred years old . A well-known theory in the academic and strategic fields, it is often the subject of…
Multidimensional political polarization in online social networks
Antonio F. Peralta, Pedro Ramaciotti, János Kertész +1
Political polarization in online social platforms is a rapidly growing phenomenon worldwide. Despite their relevance to modern-day politics, the structure and dynamics of polarized…
How research programs come apart: the example of supersymmetry and the disunity of physics
Lucas Gautheron, Elisa Omodei
According to Peter Galison, the coordination of different ``subcultures'' within a scientific field happens through local exchanges within ``trading zones''. In his view, the worka…
The Value of Information and Circular Settings
Stefan Behringer, Roman V. Belavkin
We present a universal concept for the Value of Information (VoI), based on the works of Claude Shannon's and Ruslan Stratonovich that can take into account very general preference…
Motivation literally. Construction and expression of educational aspirations on Parcoursup
Marie-Paule Couto, Marion Valarcher
This paper analyses the framing and expression of French high school students' aspirations. It sheds new light on the inequalities in tracking between academic versus technological…
Order-disorder transition in the zero-temperature Ising model on random graphs
Armin Pournaki, Eckehard Olbrich, Sven Banisch +1
The zero-temperature Ising model is known to reach a fully ordered ground state in sufficiently dense random graphs. In sparse random graphs, the dynamics gets absorbed in disorder…
Monotone Comparative Statics for Equilibrium Problems
Alfred Galichon, Larry Samuelson, Lucas Vernet
We introduce a notion of substitutability for correspondences and establish a monotone comparative static result, unifying results such as the inverse isotonicity of M-matrices, Be…
