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.

跳變馬爾可夫模型狀態(tài)估計(jì)的粒子濾波算法研究，本文在系統(tǒng)分析傳統(tǒng)粒子濾波理論與應(yīng)用問題的基礎(chǔ)上，重點(diǎn)研究了基于跳變馬爾可夫狀態(tài)空間模型的粒子濾波算法。針對(duì)混合系統(tǒng)在二維離散狀態(tài)情形下的混合狀態(tài)估計(jì)問題，給出了基于Rao-Blackwellised粒子濾波的二維離散狀態(tài)與連續(xù)狀態(tài)的同步估計(jì)算法，一定程度上緩解了傳統(tǒng)粒子濾波算法在高維狀態(tài)空間估計(jì)中的失效問題，有效提高了狀態(tài)估計(jì)的精度。應(yīng)用數(shù)值仿真計(jì)算，對(duì)相關(guān)粒子濾波算法的性能進(jìn)行了比較分析。結(jié)果表明，本文研究的算法能夠有效完成二維離散狀態(tài)與連續(xù)狀態(tài)的同步估計(jì)，其中，二維離散狀態(tài)的估計(jì)準(zhǔn)確率達(dá)到了 96％。
