Researchers have developed a novel infinite-dimensional continuous normalizing flow model to address Bayesian inference for inverse problems involving partial differential equations. This model utilizes a neural ordinary differential equation in infinite-dimensional space to transform a reference measure into a more complex one that encodes prior information. The framework is theoretically established for well-posedness in infinite-dimensional Hilbert spaces and includes training methods and sampling algorithms for Bayesian posteriors. The approach has been successfully applied to various inverse problems, including inverse scattering and heat conduction. AI
