Paris North Computer Science Laboratory

🎉Thrilled to announce that the paper "PUMA: Projected Universal Multilingual ASR for Low-Resource Settings" has been accepted at the #ACL2026 Findings Conference!
Congratulations to Ilyes Oukid, Bilal Faye, Hanane Azzag, Mustapha Lebbah and Said Yacine Boulahia, all proud members of the Laboratoire d'Informatique de Paris-Nord (LIPN).
This work was carried out in collaboration with the DAVID Laboratory at University Versailles Saint-Quentin-en-Yvelines/ Université Paris-Saclay.

See you in San Diego, USA!

Two teams from LIPN will present their joined work at IPMU 2026 👏.
Congratulations to Amal Beldi and Louenas Bounia for their work on Uncertainty-Aware Contextual Recommendation under Possible Worlds Semantics!
This paper proposes a probabilistic framework for uncertainty-aware contextual recommendation grounded in probabilistic database semantics.

🤝 This is part of a joint project between the LIPN and the IHPST (Paris), carried out by T. Seiller and A. Naibo, funded by the CNRS and the ANR.

We are pleased to announce a new publication, a long paper at #CIKM2025 (Seoul, Korea), from the A3 and RCLN teams at the LIPN laboratory, in collaboration with Centrale Supélec. This paper, titled “Dynamic Triangulation-Based Graph Rewiring for Graph Neural Networks” proposes a new graph rewiring method that dynamically selects task-relevant triangles to mitigate oversquashing in GNNs. Congratulations to Hugo Attali (LIPN), Thomas Papastergiou (LIPN), Nathalie Pernelle (LIPN) and Fragkiskos Malliaros (Centrale Supélec) ! 👏

💫 Congratulations to Aude Grezka @grezka, a CNRS Research Engineer at @LipnLab and one of the new ambassadors for the "La Science taille XX elles" program!

⚕️ New Dataset on French Medical Dispatch! We are thrilled to announce that the new SIMAMU dataset dedicated to French Medical Dispatch Dialog is accepted to the Computer Methods and Programs in Biomedicine journal. This work results from a collaboration between Inserm, Inria HeKA, AP-HP Department of Medical Informatics, and LORIA and LIPN laboratories.
🎓 Congratulations to Aimé Nun (Inserm, Inria, AP-HP), Olivier Birot (Inserm, Inria), Gaël Guibon (Sorbonne Paris Nord, LIPN, Université de Lorraine, LORIA), Frédéric Lapostolle (SAMU 93, AP-HP, Sorbonne Paris Nord) and Ivan Lerner (Inria, AP-HP) for this achievement!
🔗 You can already access the dataset on Huggingface: https://huggingface.co/datasets/medkit/simsamu

🍃 This week, on 1 April 2025, the LIPN and the LAGA are organising a day of talks on probability and combinatorics, as part of the MathSTIC federation of the Sorbonne-Paris-Nord University.
🤝 The day is co-organised by LAGA's Probability and Statistics team and LIPN's CALIN (Combinatorics, Algorithms and Interactions) team.
