Robust Recursive Estimation for Uncertain Systems With Delayed Measurements and Noises

open access: yesIEEE Access, 2020
In this article, the problem of robust recursive estimation is studied for a class of uncertain systems with delayed measurements and delayed noises. The system model is subject to stochastic uncertainties which can be described by multiplicative noises.

Recursive prediction error methods for online estimation in nonlinear state-space models [PDF]

open access: yesModeling, Identification and Control, 1994
Several recursive algorithms for online, combined state and parameter estimation in nonlinear state-space models are discussed in this paper. Well-known algorithms such as the extended Kalman filter and alternative formulations of the recursive ...

Bayesian recursive estimation on the rotation group

open access: yes2013 IEEE International Conference on Acoustics, Speech and Signal Processing, 2013
Tracking on the rotation group is a key component of many modern systems for estimation of the motion of rigid bodies. To address this problem, here we describe a Bayesian algorithm that relies on directional measurements for tracking on the special orthogonal (rotation) group.

Parameter estimation of G0 distribution based on improved recursive expectation–maximisation method for clutter modelling

open access: yesThe Journal of Engineering, 2019
Modelling and simulation of clutter are important in radar signal processing, the G0 distribution is generally adopted to simulate the ground clutter in radar echoes. In order to improve the modelling accuracy of clutter modelling, the actual data should

Optimal Nonlinear Prediction of Random Fields on Networks [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
It is increasingly common to encounter time-varying random fields on networks (metabolic networks, sensor arrays, distributed computing, etc.).This paper considers the problem of optimal, nonlinear prediction of these fields, showing from an information ...

On Asymptotically Efficient Recursive Estimation

open access: yesThe Annals of Statistics, 1978
Stochastic approximation procedures were shown by Sakrison to become asymptotically efficient estimators when used to minimize the Kullback-Leibler information, if certain conditions hold. Further results in this direction were obtained by Nevel'son and Has'minskij.

Bandwidth Selection for Recursive Kernel Density Estimators Defined by Stochastic Approximation Method

open access: yesJournal of Probability and Statistics, 2014
We propose an automatic selection of the bandwidth of the recursive kernel estimators of a probability density function defined by the stochastic approximation algorithm introduced by Mokkadem et al. (2009a).
