This talk presents a general Bayesian computation framework for performing inference in inverse problems with forward models that are partially unknown. A main novelty of the framework is that it uses MCMC-driven stochastic optimisation methods that tightly integrate modern high-dimensional Monte Carlo sampling and convex optimisation approaches. The proposed methodology is illustrated on a range of challenging imaging problems and compared to other techniques from the state of the art.
