FREESIA: Covariance-Aware Posterior Transport for Expressive and Scalable Data Assimilation

arXiv:2609.25085v1 Announce Type: new Abstract: Data assimilation aims to infer the state of complex dynamical systems based on observational data. However, accurate inference of the multimodal posteriors induced by nonlinear or non-injective observation operators remains a key challenge under high…
