Researchers have developed a new likelihood-free transport filtering method that leverages couplings between state and observation variables. This approach reformulates the filtering analysis step as a minimization of the maximum mean discrepancy (MMD) between true and approximated joint measures. The method offers an analytic computation for the transport map, avoiding particle collapse and accurately approximating non-Gaussian filtering posteriors, with demonstrated superior performance in nonlinear, non-Gaussian scenarios.
