Congratulations to @soniamazelet.bsky.social for her young talent l'Oreal women in science prize!

Frontier AI models are impacting us (researchers) in ways that we collectively need to make sense of. My colleague Pierre Marion has nicely put down his thoughts in writing in this insightful blog post. Enjoy! pierremarion23.github.io/thoughts/202...

Inverse optimization seeks to recover the parameters of an optimization problem from observed solutions. When the objective depends linearly on these parameters, the gap loss is convex, yielding a convex formulation. Inverse optimal transport is one example. www.gpeyre.com/blog/2026/10...

Important collective declaration from the best mathematicians of our time.

Bienvenue à Nice, ville avec une des plus basses températures de France ! (ps: je recrute potentiellement un.e postdoc sur 24 mois d'ici fin 2026 sur des questions, plutôt théoriques, liées aux LLMs en post-training / alignment, je dis ça, je dis rien)

As the General Chair of ISC 2026, I’m currently seeking sponsors to support students, invited speakers, awards, and community events. If your organization is interested in cybersecurity research, I’d be happy to discuss opportunities. isc2026.github.io #cybersecurity #research #infosec #ISC2026

This prize is a well deserved recognition for awesome work. If you're interested in domain adaptation, you should definitely have a look at Theo's phd thesis and pip install skada ! theses.hal.science/tel-05409110v1

I'm thrilled to have been awarded the thesis prize by the SSFAM 🥳 Thank you to the jury for the recognition you've given me 🙏 A big thanks to @rflamary.bsky.social and Alex to supporting me in this PhD! I'm looking forward to present my work at CAp 2026 in Montpellier, see you there :)

🚀 Excited to announce the release of skada v0.6.0! This new release brings important additions to the library and continued work to keep the ecosystem compatible with Sklearn!

Our work "Busemann Functions in the Wasserstein Space" was accepted at #AISTATS2026 This is a joint work with Elsa Cazelles, Lucas Drumetz and @ncourty.bsky.social. I will be presenting it tomorrow at the poster 96, see you there! Link: openreview.net/forum?id=Xpt...

My PhD thesis manuscript will be available in the coming months, but I’ve written two blog posts based on the related work chapter: 1. Generative modeling with flow-based models 🪚 2. Data-translation with flow and diffusion bridges 🔨 Open to feedback and discussions! lebellig.github.io/blog/

@tgnassou.bsky.social will present PSDnorm today at ICLR Poster Session 3 Pavilion 3. He proposed a novel layer that normalizes (using Gaussian Optimal Transport) the temporal correlation to bring more robustness to EEG signal Sleep Stage classifications. tgnassou.github.io/PSDNorm_webp...

Thibaut Germain and Karim Lounici will present today at ICLR Poster Session 3 Pavilion 3 our paper introducing the Spectral-Grassmann OT that is a proper distance between linear operators dynamical systems (Koopman) seen as distributions. It can notably be used to compute barycenters of systems.

While it is intuitively clear that straighter trajectories should reduce discretization error when integrating an ODE (for instance, in flow matching), I could not find a precise bound. I therefore rewrote the proof of Cauchy-Lipschitz to make this explicit. github.com/gpeyre/Discr...

Announcing the #ICML2026 tutorials! All ten tutorials will be presented the first day of the conference, Monday July 6. Read the blog post for more details on the selection process! blog.icml.cc/2026/04/02/a...

Today NeurIPS is announcing our official satellite event in Paris. After responding to the call from Ellis following the success of EurIPS in December, we are pleased to reach a new milestone by joining forces with the NeurIPS organizing committee for the 2026 edition.

Following the success of the EurIPS and NeurIPS-Mexico City pilots in 2025, we are thrilled to announce two official NeurIPS 2026 satellite events for this year! These will be held in Paris, France and Atlanta, USA, respectively, running alongside the main venue in Sydney, Australia.

Openreview opened the door to continuous and major revisions that nobody has time to check properly. I think that we should come back to short one pdf page replies to reviews. It would mean having decisions quicker so that we actually have time to work on papers before resubmitting them.
