**Designing attacks on the software supply chain** Binary function classifiers are generic methods that play a crucial role in monitoring the software integrity of a system, in particular by detecting backdoors, vulnerabilities and malicious code. Many classifiers are based on machine learning …

The question of whether the use of AI is justified is outdated, explains researcher Jean-Claude Planque, who argues in an article for 'Monde' that every student should be trained to make optimum use of these tools, with a sufficiently critical eye. Article in 'Le Monde' by Jean-Claude Planque, …

The study of different strategies for the '100 prisoners game' and its variants leads to interesting combinatorial problems. 'Pour la Science' article No. 57 by Jean-Paul Delahaye, Professor Emeritus in Computer Science at the University of Lille and researcher at the CRIStAL laboratory

On Tuesday 29 April, the Faculty of Science and Technology was delighted to host the regional final of the 'Faites de la Science' competition, organised by the Conference of Deans of Science (CDUS) as part of its 18th national edition. The aim of the competition is to promote scientific culture …

Like every year, CRIStAL is taking part in the 'Mai à vélo' collective chalenge. The collective aim is to cover as many kilometres as possible over 1 month (from 1 to 31 May). Last year, the University of Lille finished No.1 in the teaching category and the CNRS No.1 in the employer category.

By Jenny Sorce, CNRS Research Fellow in Cosmology, CRIStAL Laboratory Respondent Alain Vienne, Director of the Lille Astronomy Laboratory Mardi 29 avril 2025 à 18h30 The universe is infinite, as evidenced by its inordinate size, its geometric shape that is still unclear, with a rather flat …

Title: Artificial Learning: Putting into perspective half a century of evolution. Speaker: Antoine Cornuéjols The search for algorithms capable of learning bagan immediately after the definition of the Turing machine in 1936 and the development of the first computers. Recently, the …

Mathematicians disagree with each other about the nature of infinity, and in particular about the infinity of the set world. The aim of the talk will be to explain in as simple a language as possible this discussion, which is at the heart of infinity theory today. By Jean-Paul Delahaye, Professor …
