报告题目:Machine learning methods for scattering and inverse scattering problems
报告摘要: In this talk, I will describe the latest progress we have made in solving scattering problems and inverse scattering problems. For the unbounded domain scattering problem, we have designed an alternatively-optimized SNN, which is fast and accurate. Meanwhile, we design a machine learning strategy that can solve the multi-body scattering problem without prior knowledge of the number of obstacle bodies.
