Posicionamento em ambientes não estruturados e treinamento de redes neurais utilizando filtros de Kalman
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência da Computação - PPGCCCâmpus São Carlos, 2016-03-04)
Kalman filters are rooted in the technical literature, as a way of predicting new states in
nonlinear systems providing a recursive solution to the problem of linear optimal filtering.
Therefore, 56 years after its ...
Kalman Filter-Trained Recurrent Neural Equalizers for Time-Varying Channels
(Institute of Electrical and Electronics Engineers, 2005-03)
Recurrent neural networks (RNNs) have been successfully applied to communications channel equalization because of their modeling capability for nonlinear dynamic systems. Major
problems of gradient-descent learning techniques ...
PARTIAL STABILITY FOR A CLASS OF NONLINEAR SYSTEMS
(SIAM PUBLICATIONS, 2009)
This paper studies a nonlinear, discrete-time matrix system arising in the stability analysis of Kalman filters. These systems present an internal coupling between the state components that gives rise to complex dynamic ...
Non-linear Kalman filters comparison for generalised autoregressive conditional heteroscedastic clutter parameter estimation
(Institution of Engineering and Technology, 2019-08-01)
In this work, the authors analyse the estimation of the generalised autoregressive conditional heteroscedastic (GARCH) process conditional variance based on three non-linear filtering approaches: extended Kalman filter ...

Real-time Discrete Nonlinear Identification via Recurrent High Order Neural Networks
(Revista Computación y Sistemas; Vol. 14 No.1, 2010-09-30)
Abstract. This paper deals with the discrete-time nonlinear system identification via Recurrent High Order Neural Networks, trained with an extended Kalman filter (EKF) based algorithm. The paper also includes the respective ...
A Discussion Related to Orbit Determination Using Nonlinear Sigma Point Kalman Filter
(Hindawi Publishing Corporation, 2009-01-01)
Herein, the purpose is to present a Kalman filter based on the sigma point unscented transformation development, aiming at real-time satellite orbit determination using GPS measurements. First, a brief review of the extended ...
