Bayesian inversion generates a posterior distribution of model parameters from an observation equation and prior information both weighted by hyperparameters. The prior is also introduced for the hyperparameters in fully Bayesian inversions and enables us to evaluate both the model parameters and hyperparameters probabilistically by the joint posterior. However, even in a linear inverse problem, it is unsolved how we should extract useful information on the model parameters from the joint…

A proof of consistency and model-selection optimality on the empirical Bayes method
The proof validates the empirical Bayes method using the hyperparameter MMLE in the asymptotics of many model parameters, ensuring the same qualification for the empirical-cross-entropy cross-validation.


A Monte Carlo method for an objective Bayesian procedure
In the present method, there are essentially no practical restrictions in modeling the prior and the likelihood, and the Bayes estimate or the posterior mean is used mainly here in addition to the posterior mode.
Expanded uncertainty quantification in inverse problems: Hierarchical Bayes and empirical Bayes
A common way to account for uncertainty in inverse problems is to apply Bayes' rule and obtain a posterior distribution of the quantities of interest given a set of measurements. A conventional
A Bayesian approach to nonlinear inversion
This work uses Bayes' rule to show how prior information can improve the uniqueness of the optimal estimate, while stabilizing the iterative search for this estimate, and develops quantitative criteria for the relative importance of prior and observational data and for the effects of nonlinearity.
Parsimonious Bayesian Markov chain Monte Carlo inversion in a nonlinear geophysical problem
Summary A key element in the solution of a geophysical inverse problem is the quantification of non-uniqueness, that is, how much parameters of an inferred earth model can vary while fitting a set
Mixed linear-non-linear inversion of crustal deformation data: Bayesian inference of model, weighting and regularization parameters
SUMMARY We present a unified theoretical framework and solution method for probabilistic, Bayesian inversions of crustal deformation data. The inversions involve multiple data sets with unknown

Inversion Analyses Based on ABIC with Non-full Rank Prior Information
In inversion analyses using ABIC, a non-full rank matrix for prior constraints is allowed in the formulation of Yabuki and Matsu'ura (1992), while Fukuda and Johnson (2008) claimed that the matrix
The use of a priori data to resolve non‐uniqueness in linear inversion
Summary. The recent, but by now classical method for dealing with non-uniqueness in geophysical inverse problems is to construct linear averages of the unknown function whose values are uniquely
