Learning Theory for Kernel Bilevel Optimization

w/ @fareselkhoury.bsky.social E. Pauwels @michael-arbel.bsky.social

We provide generalization error bounds for bilevel optimization problems where the inner objective is minimized over a RKHS.

At the same time, I cannot write this message without telling that I am **very** worried about the current administrative evolution of our profession which is evolving quickly towards a system absolutely not calibrated to our duties with a purely accounting PoV.

(*) directeur de recherche is roughly equivalent to full prof w/o mandatory teaching duty in France. This is an incredible tenured civil servant position, and I am deeply grateful for it.

DM me if you have questions about the process to enter CNRS. There are similar position e.g. Inria

Happy to share that I have been promoted to senior research scientist (directeur de recherche (*)) at @cnrs.fr effective today! Grateful to my amazing students, collaborators and mentors who made this journey possible. I will continue my research at the math lab of UniCA @ljad-off.bsky.social.

Je viens de réaliser que mon employeur, sans me donner la possibilité d'acquérir un téléphone pro, exige une politique de sécurité sur mon code de smartphone pour accéder aux emails.

Je viens donc de faire ce que j'aurai du faire il y a dix ans : enlever mes mails pros de mon téléphone perso 🤷‍♂️

**Differentiable Generalized Sliced Wasserstein Plans**

w/
L. Chapel
@rtavenar.bsky.social

We propose a Generalized Sliced Wasserstein method that provides an approximated transport plan and which admits a differentiable approximation.

Sur le marché public de ma fac, il y a deux hotels de disponible paris intra-muros (1 mois et demi en avance). Et pas "deux" comme une manière de dire peu, DEUX = D-E-U-X = 2.

Putain de marché public à la con.
Putain de règles administratives à la con.

I still don't understand the point of 10.000 x (4~5) characters to tell "Sure I will modify 98% of the manuscrit as soon as you accept the paper" for at end just putting an additional figure p.54354 of your appendix.

This is not a rebbutal, this is begging.

I don't know if there are some stats about inter-topic disparities in scores, could be interesting.

Just for the anecdote, this is the first time I have so much high scores in my batch.

My AC batch is a proof of a large deviation principle. I have five (over 13) submissions above 4!
But your recommendation still holds ofc

Imagine if the salumiere had a machine that could slice ham automatically. There’d be nothing left for him to do :(

Congratulations to Dr. Sophie Jaffard @sophiejaffard.bsky.social for a brillant PhD defense! We were very lucky with Patricia to have you as a PhD student, and I am sure that you will have a brillant career ahead.
