Placement of Distributed Machine Learning Services for AI- and Smart Grid-Enabled IoT Platforms
No full textInternational audienceArtificial intelligence, fog computing, and smart grids allow for better energy management and personal data control. However, such heterogeneous platforms complexify service placement due to hardware and network heterogeneity. This paper proposes a distributed machine learning service for fog computing platforms model, and two new algorithms that aim to reduce time and energy consumption. The first algorithm groups services geographically, while the second places services vertically in the topology to reduce network usage. The Batsim simulator have been used to deploy distributed AI applications for measuring their duration and energy usage of the fog architecture. Results show that the first algorithm induces higher time and energy consumption than the second one, which outperforms multiple baseline algorithms for both metrics
Eating, inventing, and caring together: Ephemeral commensality in an experimental restaurant
No full textInternational audienceThis article examines how sociological research on food practices and emotions is ‘co-invented’ within experimental settings, treating cooking and eating as central to social organization. Drawing on two studies conducted at an experimental restaurant – a modular, camera-equipped space replicating cooking and dining environments – we analyze specific moments from our research through the lens of feminist reflections on the work of care in scholarly practice. Using methodographic analysis, we conceptualize eating in an experimental restaurant as a form of embodied collaborative invention emerging from interactions among humans, food, technical setups, and spatial arrangements. We identify three analytical knots: care for what bodies do and represent; care for playing with the field; and care for ephemeral commensality in collaborative cook–eat–think encounters. We argue that attention to small, often mundane moments of collaborative inventiveness nourishes an ongoing, situated quest for care in qualitative food research
Limit theorems for non linear (compound marked) Hawkes processes
No full textIn this article, we fill a gap in the literature on Hawkes processes. In particular, we derive a CLT for a non linear compound marked Hawkes process. We also provide an upper bound on the convergence rate using the functional 1-Wasserstein distance. This result is obtained by discretizing the time line and reducing the problem to the quantification of the distance between finite marginal vectors, as well as between the discretized process and the original one.</div
« Portraits de divas italiennes : Entre apparition et effacement (1560-fin xviiie siècle) »: Scènes émancipatrices, Clio. Femmes, Genre, Histoire, 2025/2 n° 62, 2025. p.41-65.
No full textInternational audienceLe texte explore l’effacement iconographique des comédiennes italiennes entre le xvie et le xviiie siècle malgré leur forte présence scénique. Si certaines comme Isabella Andreini (1562-1604) ont construit activement leur image, la plupart restent anonymes ou absentes des représentations picturales. Cette invisibilité résulte de facteurs religieux (Contre-Réforme), sociaux (misogynie), mais aussi artistiques (refus de promouvoir les comédiennes comme figures publiques). Le texte distingue sources directes (contrôlées par les artistes ou actrices) et indirectes (objets décoratifs, gravures), révélant une tendance à sexualiser ou figer les actrices. Au xviiie siècle, malgré la documentation littéraire de leurs rôles (notamment chez Goldoni), aucune iconographie ne leur survit. Cette absence de portraits souligne le paradoxe entre la visibilité scénique des actrices et leur effacement pictural. Il semblerait que l’image muette de la diva contredise la puissance expressive de son jeu, fondé sur la palette des passions. L’iconographie relative aux comédiennes dell’arte reproduit un théâtre figé, alors que leur répertoire était né avec la scène de folie fondatrice d’Isabella Andreini (La pazzia d’Isabella, Florence, 1589)

Postdoc report (PO2.1): Détection dans l'Internet des Objets
No full textLe postdoc 2.1 du PEPR Superviz vise à travailler sur la détection d’intrusion dans le cadre de réseaux composés d’objets connectés. Ce travail comporte deux volets principaux, correspondant à deux tâches T1 et T2.— Tâche T1 : compléter les travaux d’une précédente thèse réalisée au LAAS-CNRS sur la détection d’intrusion embarquée dans des contrôleurs Bluetooth Low Energy (BLE).— Tâche T2 : proposer une approche alternative aux travaux précédents en considérant une implémentation des mécanismes de détection d’intrusion dans une pile BLE en source libre
Block-Additive Gaussian Processes under Monotonicity Constraints
No full textInternational audienceWe generalize the additive constrained Gaussian process framework to handle interactions between input variables while enforcing monotonicity constraints everywhere on the input space. The block-additive structure of the model is particularly suitable in the presence of interactions, while maintaining tractable computations. In addition, we develop a sequential algorithm, MaxMod, for model selection (i.e., the choice of the active input variables and of the blocks). We speed up our implementations through efficient matrix computations and thanks to explicit expressions of criteria involved in MaxMod. The performance and scalability of our methodology are showcased with several numerical examples in dimensions up to 120, as well as in a 5D real-world coastal flooding application, where interpretability is enhanced by the selection of the blocks
