Hybrid Approaches that Combine Deterministic and Statistical Regularization for Applied Inverse ProblemsMS54

Techniques that combine deterministic and statistical methods to solve inverse problems will be the focus of the mini-symposium. The speakers and audience may range from practitioners in medical imaging to more specialized mathematicians/statisticians working on applied inverse problems. This type of blended expertise is relevant to solving applied problems in imaging, particularly ones that are ill-posed in nature including electrical impedance tomography and optical tomography. In recent years, there has been a tremendous growth in devising new techniques both deterministic and statistical, such as model reduction using reduced basis method, sparsity, Bayesian inversion, Markov Chain Monte Carlo (MCMC) methods etc. The statistical approaches are becoming more popular due to the growth of computational power in the last several decades.
