Prof. Daniel Watzenig, Graz University of Technology, Austria,

Topic: Statistical inference and uncertainty quantification

Deterministic inversion consists of applying an approximation to the inverse of the forward map, referred to as regularization, in order to give a single point estimate of the unknown parameters. These regularized solutions can provide qualitatively appealing solutions in many situations but lead to quantitatively inaccurate estimates and predictions. This property is shared by estimators in general, since conditioning on point estimates gives poor predictive densities. In contrast, Bayesian inferential methods present averages over all solutions consistent with the data. This leads to a marked difference in robustness of properties calculated from solutions. These differences occur because the single most likely solution, found by a regularized minimization of misfit to the measured data, is typically unrepresentative of the bulk of feasible solutions particularly in high dimensional nonlinear problems. Bayesian inference applied to inverse problems provides a framework for quantified model fitting. Estimation of unknown quantities of interest is based on the posterior distribution over the unknowns and unobserved data, conditioned on measured data. Uncertainty in recovered parameters arises from measurement noise, measurement sensitivities, model inaccuracy, discretization error and a priori uncertainty; each of these sources may be accounted for and in some cases taken advantage of. Estimates or properties of the unknown parameters can be calculated as summary statistics over the posterior distribution using sampling techniques. Inferential solutions to inverse problems provide substantial advantages over deterministic methods, such as:

(1) a range of parameters that are consistent with measured data can be quantified;

(2) data-dependent error estimates can be given;

(3) calculation of confidence intervals;

(4) inclusion of arbitrary forward maps and treatment of arbitrary error distributions;

(5) the parameter space can be discrete, discontinuous, or of variable dimension;

(6) treatment of non-stationary measurement data using recursive Bayesian formalism.

The proposed minisymposium will address recent advances in computational statistical inference, Bayesian analysis, numerical approximations, and quantification of model and measurement uncertainties in the probabilistic design and robust optimization of today’s engineering problems.
