New framework learns generative models and data manifolds from corrupted data

Researchers have developed Riemannian AmbientFlow, a new framework designed to simultaneously learn generative models and underlying data manifold structures from corrupted or noisy observations. This approach integrates data-driven Riemannian geometry with normalizing flows, enabling the extraction of manifold information through pullback metrics and Riemannian Autoencoders. The framework offers theoretical guarantees for recovering data distributions and provides a smooth manifold parametrization, which can also serve as a generative prior for inverse problems. AI

IMPACT This framework could improve generative modeling and data analysis in scientific applications where clean data is scarce.
