Flexible Recalibration of Approximate Bayesian Models
“The main aim of this research is to develop more flexible transformations for use with BSC (Bayesian Score Calibration). We will consider parametric and non-parametric functions, for example polynomials and Gaussian processes, respectively. Our flexible transforms should result in more accurate posterior approximations for the model of
interest, still only relying on a small number of complex model simulations. Furthermore, our approach should be more effective at recalibrating approximate posteriors over a wider region of the parameter space. There are many motivating applications which use a surrogate model to form an approximate posterior.”
