Rao-Blackwellised Particle Filtering for Dynamic Bayesian Networks
"... Particle filters (PFs) are powerful sampling-based inference/learning algorithms for dynamic Bayesian networks (DBNs). They allow us to treat, in a principled way, any type of probability distribution, nonlinearity and non-stationarity. They have appeared in several fields under such names as “conde ..."

as “condensation”, “sequential Monte Carlo” and “survival of the fittest”. In this paper, we show how we can exploit the structure of the DBN to increase the efficiency of particle filtering, using a technique known as Rao-Blackwellisation. Essentially, this samples some of the variables, and marginalizes out
Rao-Blackwellised Particle Filtering for Fault Diagnosis
- IEEE Aerospace
, 2001
"... We tackle the fault diagnosis problem using conditionally Gaussian state space models and an efficient Monte Carlo method known as Rao-Blackwellised particle filtering. In this setting, there is one different linearGaussian state space model for each possible discrete state of operation. The task of ..."

Rao-Blackwellised Particle Filtering via Data Augmentation
- In Advances in Neural Information Processing Systems
, 2001
"... In this paper, we extend the Rao-Blackwellised particle filtering method to more complex hybrid models consisting of Gaussian latent variables and discrete observations. This is accomplished by augmenting the models with artificial variables that enable us to apply Rao-Blackwellisation. Other improv ..."

Rao-Blackwellised particle filtering for blind system identification
- In Proceedings of the IEEE International Conference on Acoustics, Speech, and Signal Processing
, 2005
"... This paper develops a Rao-Blackwellised particle filtering algo-rithm for blind system identification. The state space model un-der consideration uses a time-varying autoregressive (AR) model for the sources, and a time-varying finite impulse response (FIR) model for the channel. The multi-sensor me ..."

The class of “Rao-Blackwellised ” particle filters exploits the analytic marginalisation that is possible for some state-space models to reduce the variance of the Monte Carlo estimates. Despite being applicable to only a restri ..."

Rao-Blackwellised Particle Filter for Tracking with Application
- in Visual Surveillance”, the Second Joint IEEE International Workshop on Visual Surveillance and Performance Evaluation of Tracking and Surveillance (VS-PETS), in conjunction with ICCV 2005, Oct
"... Particle filters have become popular tools for visual tracking since they do not require the modeling system to be Gaussian and linear. However, when applied to a high dimensional state-space, particle filters can be inefficient because a prohibitively large number of samples may be required in orde ..."

After using only anonymous sensors until id estimates are certain enough, id assignments are sampled as well
