An EM Algorithm for Lebesgue-sampled State-space Continuous-time System Identification

no code implementations6 Apr 2023 Rodrigo A. González, Angel L. Cedeño, María Coronel, Juan C. Agüero, Cristian R. Rojas

This paper concerns the identification of continuous-time systems in state-space form that are subject to Lebesgue sampling.

On Recursive State Estimation for Linear State-Space Models Having Quantized Output Data

no code implementations15 Dec 2021 Angel L. Cedeño, Ricardo Albornoz, Boris I. Godoy, Rodrigo Carvajal, Juan C. Agüero

We consider a new approach based on the Gaussian sum filter/smoother where the probability mass function of the quantized data given the state is modeled as an integral equation and approximated using Gauss-Legendre quadrature.

Quantization

A MAP approach for $\ell_q$-norm regularized sparse parameter estimation using the EM algorithm

no code implementations5 Aug 2015 Rodrigo Carvajal, Juan C. Agüero, Boris I. Godoy, Dimitrios Katselis

In this paper, Bayesian parameter estimation through the consideration of the Maximum A Posteriori (MAP) criterion is revisited under the prism of the Expectation-Maximization (EM) algorithm.
