New framework uses learned surrogates for data assimilation

Researchers have developed a new framework for continuous data assimilation, which aims to estimate the state of a dynamical system using limited observations. This method addresses challenges where the system's dynamics are unknown or computationally expensive to simulate by employing learned machine learning surrogates. The analysis shows that using these surrogate models can maintain accurate tracking, with convergence dependent on approximation and observation noise errors, and quantifies the training data needed for precise assimilation.
