Researchers have developed a new method called the proper scoring ensemble filter (PSEF) for Bayesian filtering of dynamical systems. This transformer-based map approximates the filtering distribution using synthetic state-observation trajectories and is trained with strictly proper scoring rules, such as the energy score, to reward probabilistic accuracy. Numerical experiments demonstrate that PSEF can accurately approximate complex filtering distributions, including nonlinear, non-Gaussian, and multi-modal posteriors, outperforming classical and other learning-based methods in data assimilation tasks.
