Statistical inverse learning problems with random observations

Abhishake Rastogi, Tapio Helin, Nicole Mücke

We provide an overview of recent progress in statistical inverse problems with random experimental design, covering both linear and nonlinear inverse problems. Different regulariza…

Least squares approximations in linear statistical inverse learning problems

Tapio Helin

Statistical inverse learning aims at recovering an unknown function from randomly scattered and possibly noisy point evaluations of another function , connected to via a…

Stability estimates for the expected utility in Bayesian optimal experimental design

Duc-Lam Duong, Tapio Helin, Jose Rodrigo Rojo-Garcia

We study stability properties of the expected utility function in Bayesian optimal experimental design. We provide a framework for this problem in a non-parametric setting and prov…

Hyperparameter Estimation in Bayesian MAP Estimation: Parameterizations and Consistency

Matthew M. Dunlop, Tapio Helin, Andrew M. Stuart

The Bayesian formulation of inverse problems is attractive for three primary reasons: it provides a clear modelling framework; means for uncertainty quantification; and it allows f…

Rates of contraction of posterior distributions based on -exponential priors

Sergios Agapiou, Masoumeh Dashti, Tapio Helin

We consider a family of infinite dimensional product measures with tails between Gaussian and exponential, which we call -exponential measures. We study their measure-theoretic…

Generalized modes in Bayesian inverse problems

Christian Clason, Tapio Helin, Remo Kretschmann +1

Uncertainty quantification requires efficient summarization of high- or even infinite-dimensional (i.e., non-parametric) distributions based on, e.g., suitable point estimates (mod…
