... August 31, 2014 Abstract The resolution of many large-scale inverse problems using MCMCmethods requires a step of drawing samples from a high dimensional Gaussian distribution. While direct Gaussian ...

... The outer Monte Carlo stage samples distributions restricted to {Y ∈ A}. A naive acceptance-rejection on Y fails to be efficient because most of simulations of Y are wasted. Therefore, specific rare-event techniques have ...
