We test our method on a checkerboard distribution on the sphere 🏁🌐, yielding promising results when compared to Euclidean and non-variational methods.

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. 🌍🌎🌏

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! 💅💪

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!!
