Reposted by Olga ZaghenFloor Eijkelboom @eijkelboomfloor.bsky.social · 19/02/2025Super excited about this project!! Amazing work by @olgatticus.bsky.social and others ❤️ 041
Olga Zaghen @olgatticus.bsky.social · 19/02/2025Stay tuned for further analyses and experiments! ✨ A huge thanks to my brilliant collaborators for all their efforts and invaluable guidance: @eijkelboomfloor.bsky.social, @alisometry.bsky.social and @erikjbekkers.bsky.social 🔥 🧵5/5 030
Olga Zaghen @olgatticus.bsky.social · 19/02/2025We test our method on a checkerboard distribution on the sphere 🏁🌐, yielding promising results when compared to Euclidean and non-variational methods. 🧵4/5 120
Olga Zaghen @olgatticus.bsky.social · 19/02/2025By 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. 🌍🌎🌏 🧵3/5 120
Olga Zaghen @olgatticus.bsky.social · 19/02/2025Inspired 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! 💅💪 🧵2/5 130
Olga Zaghen @olgatticus.bsky.social · 19/02/2025Variational 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.

Reposted by Olga ZaghenMax Zhdanov @maxxxzdn.bsky.social · 26/01/2025This 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. 161
