AB: The focus of inverse problems often is on the construction of a model. The user of inverse problems is, however, rarely interested in a model. Inverse problems are in practice used for making decisions that associated with academic issues, business decisions, or risk analysis. The uncertainty in the models is often extremely difficult to quantify. For linear inverse problems the size of the inverse problems is a real hurdle. For nonlinear inverse problems there is no theory to quantify the uncertainty in models. Stochastic methods can be used for this purpose, but their applicability is limited to relatively small-scale inverse problems. In this presentation I will sketch a number of open research questions that are crucial for using inverse problems effectively in decision making.
