Abstract :
Particle filter is a Monte Carlo method to monitor dynamic systems, which non-parametrically approximates probabilistic distribution using weighted samples. Particle filters have been widely used in various fields such as robotics, visual tracking, etc. A key issue for fast implementation of particle filter is how to determine the sample size (particle number) according the sample based distribution. The paper presents a sample size adaptation scheme for particle filters. The key idea is to adjust sample size according to the distance of two sample-based distributions with different sample scale. The method is testified on nonlinear system estimation problem.
