A stochastic covariance shrinkage approach to particle rejuvenation in the ensemble transform particle filter

<p>Rejuvenation in particle filters is necessary to prevent the collapse of the weights when the number of particles is insufficient to properly sample the high-probability regions of the state space. Rejuvenation is often implemented in a heuristic manner by the addition of random noise that...
