Interested in the analysis of GNN expressive power, limitations of the WL test or more in general in the definition of complete metrics on graphs? 👀
Check out this super cool work led by

have fun!!! 🔥
Super happy to share our work was accepted as an Oral at the Delta Workshop @ ICLR 2025! 🎉
Can’t wait to talk about it in Singapore 😎
Congrats to the amazing team @eijkelboomfloor.bsky.social @alisometry.bsky.social @erikjbekkers.bsky.social 🔥

🧵5/5
We test our method on a checkerboard distribution on the sphere 🏁🌐, yielding promising results when compared to Euclidean and non-variational methods.
🧵4/5
By directly encoding the manifold, we introduce Riemannian-Gaussian-VFM, offering a fresh perspective on geometry-informed generative modeling. We also discuss how our approach relates to the previously mentioned methods. 🌍🌎🌏
🧵3/5
Inspired by Riemannian Flow Matching, we extend the Variational Flow Matching (VFM) objective to build a geometry-aware flow model. 🌊
Interestingly, VFM is particularly well-suited for explicitly parametrizing the support manifold of the distribution! 💅💪

Variational Flow Matching goes Riemannian! 🔮
In this preliminary work, we derive a variational objective for probability flows 🌀 on manifolds with closed-form geodesics, and discuss some interesting results.

We're excited to announce ComBayNS workshop: Combining Bayesian & Neural Approaches for Structured Data 🌐
Submit your paper and join us in Rome for #IJCNN2025! 🇮🇹
📅 Papers Due: March 20th, 2025 📜

🌟 Call for Papers – ComBayNS Workshop at IJCNN 2025 🌟
Workshop page: combayns2025.github.io
We are thrilled to announce the #workshop “ComBayNS: Combining Bayesian and Neural approaches for Structured data” at the upcoming International Joint Conference on Neural Networks (#IJCNN).
A thread 🧵
This is how it should be: one file, ctrl+c ctrl+v runnable from a notebook. I really do not want to mess with omegaconf, hydra or, the worst, a custom configuration system just to figure out how your model runs.

❤️❤️❤️
of course !!
we also celebrate it in some areas of Italy - like where I come from - where "Santa Lucia" is even more popular than Santa Claus for children!!
haters will say photoshop!!
