Maximum likelihood parameter estimation for latent variable models using sequential Monte Carlo [PDF]
We present a sequential Monte Carlo (SMC) method for maximum likelihood (ML) parameter estimation in latent variable models. Standard methods rely on gradient algorithms such as the ExpectationMaximization (EM) algorithm and its Monte Carlo variants. Our

Maximum a posteriori vs maximum probability recursive sparse estimation [PDF]
Recursive sparse parameter estimates obtained using the author's recent maximum a posteriori (MAP) approach, where the sparse parameter estimates are determined as the a posteriori mode of a Gaussian sum filter, are compared with a new maximum probability (MP) methodology, where the sparse parameter estimates are determined as the component of a ...

Maximum-a-Posteriori Estimation with Bayesian Confidence Regions [PDF]
Solutions to inverse problems that are ill-conditioned or ill-posed may have significant intrinsic uncertainty. Unfortunately, analyzing and quantifying this uncertainty is very challenging, particularly in high-dimensional problems. As a result, while most modern mathematical imaging methods produce impressive point estimation results, they are ...

Adaptive QRS Detection Based on Maximum A Posteriori Estimation [PDF]
A mathematical model for the occurrence of nonoverlapping pulse-shaped waveforms corrupted with colored Gaussian noise is considered for the purpose of QRS detection. The number of waveforms, the arrival times, amplitudes, and widths are regarded as random variables.

Applications of single valued trapezoidal neutrosophic maximum a posteriori estimation in real-life problems [PDF]
In this paper, we introduce Single-Valued Trapezoidal Neutrosophic Maximum a Posteriori (SVTN-MAP) estimation to deal with uncertainty in prior distribution parameters, where prior parameters are assumed to be Single-Valued Trapezoidal Neutrosophic ...

The multi-baseline InSAR can effectively reduce the adverse effect caused by the abrupt change of the target and the large noise disturbance and can obtain the Digital Elevation Model (DEM) that is more accurate than the single baseline InSAR ...

A Posteriori Error Estimates in the Maximum Norm for Parabolic Problems [PDF]
We derive a posteriori error estimates in the $L_\infty((0,T];L_\infty(\Omega))$ norm for approximations of solutions to linear parabolic equations. Using the elliptic reconstruction technique introduced by Makridakis and Nochetto and heat kernel estimates for linear parabolic problems, we first prove a posteriori bounds in the maximum norm for ...

On Maximum a Posteriori Estimation of Hidden Markov Processes
We present a theoretical analysis of Maximum a Posteriori (MAP) sequence estimation for binary symmetric hidden Markov processes. We reduce the MAP estimation to the energy minimization of an appropriately defined Ising spin model, and focus on the performance of MAP as characterized by its accuracy and the number of solutions corresponding to a ...

Signal waveform estimation in the presence of uncertainties about the steering vector [PDF]
We consider the problem of signal waveform estimation using an array of sensors where there exist uncertainties about the steering vector of interest. This problem occurs in many situations, including arrays undergoing deformations, uncalibrated arrays ...
