Scientific Goals: The workshop aims at bringing together leading researchers in the area of statistical inference for inverse problems, to discuss and initiate the development of rigorous mathematical foundations for commonly used `uncertainty quantification’ methodology. The main focus is on the development of objective data-driven measures that can guarantee that algorithms used in statistical inverse problems have actually returned an accurate solution. Traditional statistical methods insist in the construction of `confidence sets’ or `algorithmic certificates’ for the parameters of inferential interest, but in complex parameter spaces such as those encountered in inverse problems, this is often a very difficult task. Alternatively, Bayesian methodology (posterior inference, credible sets, Bayes factors, etc) is frequently used, but even disregarding computational barriers, the objective (frequentist) meaning of posterior based-inferences is largely unclear in such settings. The workshop will try to push forward the frontiers of this research area by combining expertise from a variety of concrete application areas within statistical inverse problems with recent advances on the inferential foundations of non-parametric and high-dimensional statistics. The hope is that a rigorous mathematical paradigm emerges that can serve as a foundation for uncertainty quantification in modern day statistical inverse problems.
