Researchers have developed the Score Kalman Filter (SKF), a novel approach to nonlinear Bayesian filtering that bypasses the computationally expensive partition function. By integrating score matching with Stein's identity, the SKF simplifies density fitting to a linear solve and closes moment hierarchies efficiently. This method allows for filtering in higher dimensions, demonstrated up to n=20, and achieves lower RMSE than established baselines on synthetic benchmarks. AI
