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-Blackwell theorem (sometimes called the Rao–Blackwell–Kolmogorov theorem or Rao-Blackwellization) is a way to improve the efficiency of initial estimators. Estimators are observable random variables used to estimate quantities. For example, the (observable) sample mean is an estimator for the (unknown) population mean.

Tīmeklis2015. gada 19. maijs · 1 Answer. Sorted by: 2. To find the conditional expectation E [ n X ( 1) ∣ T] as part of the Rao-Blackwellization, we can use the independence between X ( 1) T and T. This independence can be argued by Basu's theorem since T = ∑ i = 1 n X i is a complete sufficient statistic and X ( 1) T = X ( 1) / λ T / λ is an ancillary statistic, …
Tīmeklis2024. gada 18. jūn. · This becomes our new, Rao-Blackwellized, estimator. That sounds great, but what is a sufficient statistic? Informally, a function of the data T is sufficient if we can’t learn anything more about the parameter of interest from the distribution of the data if we already know what T is.
