Applied Mathematics in EM Studies with Special Emphasis on an Uncertainty Quantification and 3-D Integral Equation Modelling
TL;DR: A variant of the M–H method is introduced which uses information about the local gradient and Hessian of the penalty function to exploit adjoint-based machinery that has been instrumental for the fast solution of deterministic inverse problems and why this modification of M-H significantly accelerates sampling of the posterior probability distribution.
