Empirical Bayesian regularization of the inverse acoustic problem

A Pereira, J Antoni, Q Leclere - Applied Acoustics, 2015 - Elsevier
This paper answers the challenge as how to automatically select a good regularization
parameter when solving inverse problems in acoustics. A Bayesian solution is proposed that …

Regularization, Bayesian inference, and machine learning methods for inverse problems

A Mohammad-Djafari - Entropy, 2021 - mdpi.com
Classical methods for inverse problems are mainly based on regularization theory, in
particular those, that are based on optimization of a criterion with two parts: a data-model …

Spectral matrix completion by cyclic projection and application to sound source reconstruction from non-synchronous measurements

L Yu, J Antoni, Q Leclere - Journal of Sound and Vibration, 2016 - Elsevier
A fundamental limitation of the inverse acoustic problem is determined by the size of the
array and the microphone density. A solution to achieve large array and/or high microphone …
