The software implements particle filtering and Rao Blackwellised particle filtering for conditionally Gaussian Models. The RB algorithm can be interpreted as an efficient stochastic mixture of Kalman filters. The software also includes efficient state-of-the-art resampling routines. These are generic and suitable for any application.

Rao-Blackwellised Particle Filters (RBPFs) are a class of Particle Filters (PFs) that exploit conditional dependencies between parts of the state to estimate. By doing so, RBPFs can improve the estimation quality while also reducing the overall computational load in comparison to original PFs. However, the computational complexity is still too high for many real-time applications. In this paper, we propose a modified RBPF that requires a single Kalman Filter (KF) iteration per input sample. Comparative experiments show that while good convergence can still be obtained, computational efficiency is always drastically increased, making this algorithm an option to consider for real-time implementations.

n this demo, we show how to use Rao-Blackwellised particle filtering to exploit the conditional independence structure of a simple DBN. The derivation and details are presented in A Simple Tutorial on Rao-Blackwellised Particle Filtering for Dynamic Bayesian Networks. This detailed discussion of the ABC network should complement the UAI2000 paper by Arnaud Doucet, Nando de Freitas, Kevin Murphy and Stuart Russell. After downloading the file, type "tar -xf demorbpfdbn.tar" to uncompress it. This creates the directory webalgorithm containing the required m files. Go to this directory, load matlab5 and type "dbnrbpf" for the demo.

跳变马尔可夫模型状态估计的粒子滤波算法研究，本文在系统分析传统粒子滤波理论与应用问题的基础上，重点研究了基于跳变马尔可夫状态空间模型的粒子滤波算法。针对混合系统在二维离散状态情形下的混合状态估计问题，给出了基于Rao-Blackwellised粒子滤波的二维离散状态与连续状态的同步估计算法，一定程度上缓解了传统粒子滤波算法在高维状态空间估计中的失效问题，有效提高了状态估计的精度。应用数值仿真计算，对相关粒子滤波算法的性能进行了比较分析。结果表明，本文研究的算法能够有效完成二维离散状态与连续状态的同步估计，其中，二维离散状态的估计准确率达到了 96％。
