arXiv:2606.16273v1 Announce Type: cross Abstract: We introduce, to our knowledge, the first deep generative modeling framework for probability distributions continuously supported on compact metric graphs. Given source and target measures on a metric graph, our method embeds the graph into a smooth ambient space, solves an entropic Kantorovich problem via a neural semidual parameterization, and projects generated samples back onto the original graph. We study two embedded geometries: an extrinsic Euclidean realization and the intrinsic tropical Abel--Jacobi embedding into the Jacobian torus. I
The continuous evolution of deep learning architectures and computational methods is enabling new approaches to generative modeling, pushing beyond Euclidean data constraints.
This research represents a significant step towards generative AI on non-Euclidean data structures, critical for applications in fields like molecular design, transportation networks, and social graphs.
Current generative models primarily operate on Euclidean data; this introduces a foundational framework for continuous generative modeling on metric graphs, expanding the scope of what AI can generate and understand.
