"TīmeklisMurphy, Doucet, and colleagues [7, 9] introduced Rao-Blackwellized particle ﬁl-ters (RBPFs) as an effective means to solve the SLAM problem. The main problem of Rao-Blackwellized particle ﬁlters lies in their complexity, measured in terms of the number of particles required to learn an accurate map.

Tīmeklis2007. gada 1. janv. · 1.. IntroductionIn [1] we proposed a Rao-Blackwellized particle filtering based multiple target tracking algorithm called Rao-Blackwellized Monte Carlo data association (RBMCDA). In this article we extend the RBMCDA algorithm to tracking an unknown and time varying number of targets.In the proposed algorithm, not only … TīmeklisThe Rao-Blackwellized Particle Filter (RBPF) as you say in your question performs a marginalization of the probability distribution of your state space. The particle filter uses sampling to represent the multivariate probability distribution of your state space. Using samples to represent a distribution is firstly only an approximation, and ...
