New von Mises ensemble improves uncertainty quantification for automotive radar

Researchers have developed a new uncertainty quantification method for automotive radar systems using a von Mises (VM) ensemble, which offers improved interpretability and geometric consistency compared to evidential deep learning (EDL). The VM ensemble provides angular predictions with parameters (mu, kappa) that allow for direct probabilistic integration into detection and tracking pipelines. While EDL shows smoother uncertainty variation, the VM approach demonstrates better performance under nominal conditions and greater sensitivity to severe perturbations, highlighting a trade-off between geometric consistency and statistical generality.
