讲座简介:
Inverse scattering problems arise from many important applications. In this talk, we propose a new method combining the non-iterative method and the Bayesian approach. The problem is formulated as a statistical model using the Bayes’ formula. The well-posedness is proved in the sense of the Hellinger metric. The direction method is used to obtain information to construct priors, which is critical to the convergence of the MCMC algorithm. In particular, we study some inverse scattering problems with non-unique solutions and demonstrate the performance of the proposed method.
