The 2024 doctoral fellowship from the LIA has been awarded to the Cornet team. Several topics have been proposed, and they are available on the Adum platform. In alphabetical order by title: Interested candidates should apply on the Adum platform. Most importantly, before doing so, contact the researchers who propose the topics to discuss them further.
As part of the national synchronized recruitment campaign for teaching and research faculty in 2024, Avignon University is offering a position for an Assistant Professor in Computer Science. Teaching will take place at the Avignon University Institute of Technology, mainly in the field of Data Science, and research will be conducted at the LIA (Avignon University CS Lab). The position description is available here (in French): https://univ-avignon.fr/wp-content/uploads/2024/02/4222-IUT-MCF-27.pdf
The next seminar of the Cornet team will take place on February 23, 2024, at 11:35 a.m. in S3, and will consist of two parts. First, Sylvie Chaddad (LIA) will present her thesis topic on Stochastic Control for Optimizing Crowdfunding Project Dynamics. Then, Lorena Garrido (University of Veracruz) will present her work titled On the Monge-Kantorovich divergence. Abstract: The Monge-Kantorovich divergence is a measure of closeness between probability distributions. Historically, it arises from an optimal transport problem of sand movement, in the area of civil engineering. Today, the Monge-Kantorovich problem has given rise to many theoretical studies, as well as various applications, including data analysis. In this talk, a couple of applications in data analysis will be mentioned.
Congratulations to Grace Tessa Masse and Abderrahim Benslimane, for the best paper award they obtained at International Conference on Computing, Networking and Communications (IEEE ICNC 2024) Title: A Secure Hierarchical Federated Learning Using Dirichlet-based Trust Management Abstract—Hierarchical Federated Learning (HFL) is a distributed machine learning training system in which a server works with several clients and edge nodes while maintaining data privacy. Distributed machine learning training systems are also known as Federated Learning, but HFL is a type of Federated Learning that utilizes a hierarchical network architecture to address computational issues when dealing with a high number of clients. However, HFL is vulnerable to attacks such as data poisoning, which may jeopardize the entire training process and result in misclassifications. As system defenders, we have to tackle this issue. Using a label-flipping attack, we investigate the effect of data poisoning attacks on HFL training. We propose a trust management-based strategy to mitigate data poisoning attacks, which assesses client trustworthiness using a Dirichlet distribution. We maintain a record of previous activities, allowing the server to enhance its knowledge based on client reliability. We demonstrate the proposed approach’s effectiveness through improvements in model performance after removing malicious clients, using the MNIST dataset Plus d'infos
Thibault Roux will organize a debate on the subject mentioned below: “Recent advances in technology have raised many questions and concerns about their impact on our societies. Many people are concerned about military use, mass surveillance or disinformation. From a more global perspective, Nick Bostrom, a philosopher, theorizes the vulnerable world hypothesis which predicts that science will destroy humanity.In this debate, we will question our own biases as researchers and try to answer the ethical questions raised by this hypothesis. Is science a threat to humanity? Should we stop science? Or more seriously, can we find a solution to prevent ourselves from self-destruction ?”
À l’occasion de la journée internationale des femmes en sciences, qui a lieu cette année le dimanche 11 février, le comité égalité-diversité du LIA organise une journée de conférences le vendredi 16 février 2024. Ces conférences seront menées par Cécile Favre, de l’université Lyon 2. Conférence 1: (de 10h à 11h30) Lieu : Amphi Ada Lovelace Titre : La « science des données » au prisme des études de genre : objet de recherche et source de questionnements méthodologiques pour la scientométrie. Le cas du défi EGC 2020. Résumé : Cette communication s’appuie sur le défi lancé par l’association EGC (Extraction et Gestion des Connaissances) qui rassemble des chercheuses et des chercheurs travaillant au croisement de l’informatique et des statistiques, en « science des données ». Pour la 20ème édition de sa conférence annuelle, l’association a mis à disposition des matériaux la concernant en vue de leur analyse. Les matériaux empiriques proposés sont notamment les actes publiés, l’ensemble des emails envoyés sur sa liste de diffusion. Nous avons complété ces matériaux avec des éléments récoltés sur le site Web concernant l’organisation des 19 éditions de la conférence tels que les conférences invitées, les comités de lecture, les comités d’organisation, etc. Plus d'infos
