A Robust Sparse Bayesian Learning-Based DOA Estimation Method With Phase Calibration

open access: yesIEEE Access, 2020
Usually, the array manifolds are assumed to be known perfectly in the radar systems, but the imprecise knowledge substantially degrades the performance of estimating the direction of arrival (DOA).

Low-Rank and Sparse Matrix Recovery for Hyperspectral Image Reconstruction Using Bayesian Learning

open access: yesSensors, 2022
In order to reduce the amount of hyperspectral imaging (HSI) data transmission required through hyperspectral remote sensing (HRS), we propose a structured low-rank and joint-sparse (L&S) data compression and reconstruction method.

Multimodal Sparse Bayesian Dictionary Learning

open access: yesCoRR, 2018
This paper addresses the problem of learning dictionaries for multimodal datasets, i.e. datasets collected from multiple data sources. We present an algorithm called multimodal sparse Bayesian dictionary learning (MSBDL). MSBDL leverages information from all available data modalities through a joint sparsity constraint.

Bayesian orthogonal component analysis for sparse representation [PDF]

open access: yes, 2010
This paper addresses the problem of identifying a lower dimensional space where observed data can be sparsely represented. This under-complete dictionary learning task can be formulated as a blind separation problem of sparse sources linearly mixed with ...

Identification of nonlinear sparse networks using sparse Bayesian learning [PDF]

open access: yes2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017
This paper considers a parametric approach to infer sparse networks described by nonlinear ARX models, with linear ARX treated as a special case. The proposed method infers both the Boolean structure and the internal dynamics of the network. It considers classes of nonlinear systems that can be written as weighted (unknown) sums of nonlinear functions ...

Sparse Bayesian Modeling With Adaptive Kernel Learning [PDF]

open access: yesIEEE Transactions on Neural Networks, 2009
Sparse kernel methods are very efficient in solving regression and classification problems. The sparsity and performance of these methods depend on selecting an appropriate kernel function, which is typically achieved using a cross-validation procedure.
