Generalized Bayes Approach to Inverse Problems with Model Misspecification
Youngsoo Baek, Wilkins Aquino, Sayan Mukherjee
We propose a general framework for obtaining probabilistic solutions to PDE-based inverse problems. Bayesian methods are attractive for uncertainty quantification but assume knowle…
Plane Wave Elastography: A Frequency-Domain Ultrasound Shear Wave Elastography Approach
Reza Khodayi-mehr, Matthew W. Urban, Michael M. Zavlanos +1
In this paper, we propose Plane Wave Elastography (PWE), a novel ultrasound shear wave elastography (SWE) approach. Currently, commercial methods for SWE rely on directional filter…
Adaptive particle-based approximations of the Gibbs posterior for inverse problems
Zilong Zou, Sayan Mukherjee, Harbir Antil +1
In this work, we adopt a general framework based on the Gibbs posterior to update belief distributions for inverse problems governed by partial differential equations (PDEs). The G…
Analysis of the error in constitutive equation approach for time-harmonic elasticity imaging
Wilkins Aquino, Marc Bonnet
We consider the identification of heterogeneous linear elastic moduli in the context of time-harmonic elastodynamics. This inverse problem is formulated as the minimization of the…
Model-Based Active Source Identification in Complex Environments
Reza Khodayi-mehr, Wilkins Aquino, Michael M. Zavlanos
We consider the problem of Active Source Identification (ASI) in steady-state Advection-Diffusion (AD) transport systems. Unlike existing bio-inspired heuristic methods, we propose…
