Sparsity-promoting hierarchical Bayesian model for EIT with a blocky target
Daniela Calvetti, Monica Pragliola, Erkki Somersalo
The electrical impedance tomography (EIT) problem of estimating the unknown conductivity distribution inside a domain from boundary current or voltage measurements requires the sol…
An efficient hierarchical Bayesian method for the Kuopio tomography challenge 2023
Monica Pragliola, Daniela Calvetti, Erkki Somersalo
The aim of Electrical Impedance Tomography (EIT) is to determine the electrical conductivity distribution inside a domain by applying currents and measuring voltages on its boundar…
Distributed Tikhonov regularization for ill-posed inverse problems from a Bayesian perspective
Daniela Calvetti, Erkki Somersalo
We exploit the similarities between Tikhonov regularization and Bayesian hierarchical models to propose a regularization scheme that acts like a distributed Tikhonov regularization…
