Microblog & Links

With the ICML 2026 deadline, I forgot to mention that together with Sofiane Tanji and Yassine Laguel, we have a new preprint Fairness-informed Pareto Optimization: An Efficient Bilevel Framework. If you like fairness or multiobjective optimization or bilevel optimization, you won’t be disappointed to skim it!

After the 2168 series, I read Fabien Sanglard’s series on building a Quake PC (late 90s-style), it brings back so much memories!

I tested Pocket TTS from Kyutai. It’s fun to use for generating French sentences: the accent is strong, but it’s still perfectly understandable, even though French doesn’t seem to be in the training dataset.

Beyond that, the model is quite impressive especially knowing it has only 100M parameters

Just vibecoded a simple microblog editor that takes advantage of GitHub OAuth and Netlify functions to post to my static site.

I finally switched this website from my custom hacky Rust static site generator to hugo using amp. Also, I deploy it automatically from GitHub to Netlify like a normal human being in 2026.

My writings are on /w and I created also a “microblog”-style at /m. I imported some my news / changelog to to this /m section

I will be in San Diego for NeurIPS (December 2-6).

Léo Davy defended his PhD thesis (supervisors: Nelly Pustelnik and Patrice Abry) that I had the pleasure to review. Congrats!

I gave a talk at the Séminaire Math-IA in Bordeaux on Geometrical and computational complexity of bilevel optimization.

I am the CIRM this week for the (Blind) inverse problems in imaging: from foundations to applications workshop organized by Luca, Emmanuel and Pierre.

Starting today, I am officially promoted Directeur de recherche at CNRS.

Tùng Nguyễn Thanh just started his PhD with Yassine Laguel and myself.

I am in Berkeley this week for the Graph Learning Meets Theoretical Computer Science workshop at the Simons Institute for the Theory of Computing.

I am visiting Nicolas Keriven in Rennes this week.

Sophie Jaffard defended his PhD thesis on Spiking neural networks : learning as point processes. Congrats to her! It was a pleasure to supervise her with Patricia Reynaud-Bouret.

I present at Café calcul from Groupe Calcul. I introduce automatic differentiation: from the chain rule and Jacobians to forward and reverse modes (backprop) via computational graphs, showing simple implementations, semantic interpretations, and a glimpse of theory for iterative algorithms.

I gave a talk at the joint seminar between the Probability and Statistics team of the LJAD and the Inria MASAAI team on some advances on nonconvex bilevel optimization.

I gave a talk at MaLGa in Genoa, hosted by L. Calatroni.

Our paper Geometric and computational hardness of bilevel programming has been accepted to Math. Prog!

I give a talk at GDR IASIS day on bilevel optimization in Lyon.
