présentation

Lens Computer Science Research Lab (CRIL UMR 8188) is a joint laboratory between Université d’Artois and CNRS, that has a strong research focus on Artificial Intelligence and its applications. It groups together about 70 members, including researchers, lecturers, PhD students, postdocs and administrative or technical staff.

The CRIL is a member of the Confederation of Laboratories for Artificial Intelligence Research in Europe of the regional humAIn alliance. It is funded by Ministère de l’Enseignement Supérieur et de la Recherche, CNRS, Université d’Artois and Hauts de France region.

CRIL is located in two different places in Lens: at the faculty of science and at the technical institute (IUT).

PhD positions From AI to Propositional Logic: Conversion to SAT and Model Analysis

This thesis topic aims to create a bridge between artificial intelligence (AI) solutions and formal techniques of classical propositional logic. It seeks to develop generic methods for transforming AI models into propositional formulas, focusing on the satisfiability problem, known as the SAT. This approach looks to leverage the significant advancements made in the field of SAT solvers. A key aspect of this work is identifying the important features of AI models that can be efficiently translated into SAT representations.

PhD positions Deep Graph Representation Learning on non-uniform 3D objects

This thesis focuses on deep learning, with an emphasis on learning graph representations. Graphs are widely used in many applications, providing a versatile representation for non-regular objects, including 3D meshes, as an alternative to traditional methods such as CNNs or image segmentation models like U-net. This thesis explores graph neural networks (GNNs) for modeling non-regular 3D objects, such as 3D meshes. Unlike CNNs, GNNs are designed to handle graph-type data, making them more suitable for representing 3D meshes.
