📣 New preprint 📣

**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.

Unsupervised Learning for Optimal Transport plan prediction between unbalanced graphs

Optimal transport between graphs, based on Gromov-Wasserstein and other extensions, is a powerful tool for comparing and aligning graph structures. However, solving the associated non-convex optimizat...

My point is rather that typst language is much more human-readable than LaTeX and as a result, I feel cetz is a relief compared to TikZ

TikZ equivalent in typst is cetz, and it is such a pleasure to write code for TikZ-like diagrams in a language that is human-readable

Same here, and one of the 2 reviewers whose score disappeared explicitly stated in their review that they would update their score.

I love the #eurips initiative! But to live up to its potential, it should be accepted an official #neurips conference location (similar to Mexico City) and not just an addon! Then we would save C02, rather than adding to it!!! What can we do to achieve this?

This is awful! We need to treat our scientists better if we want to do good science. This means consistent funding for tenure that allows time for risky but novel discoveries and not only short-time projects and infinite post-docs. www.science.org/content/arti...

My academic job offer was rescinded. I’ll keep going—but U.S. researchers are running out of road

Despite an uncertain future, this postdoc will “keep doing the science I love while I still have a bench”

New paper on the generalization of Flow Matching www.arxiv.org/abs/2506.03719

🤯 Why does flow matching generalize? Did you know that the flow matching target you're trying to learn *can only generate training points*?
