If you have a question about this talk, please contact Sergey Sergeev. Inverse problems involve the reconstruction of hidden objects from possibly noisy indirect measurements and are ubiquitous in a variety of scientific and engineering applications. This kind of problems have two main features that make them interesting yet challenging to solve. First, they tend to be ill-posed: the reconstruction is very sensitive to perturbations in the measurements. Second, real-world applications are often large-scale: resulting in computationally demanding tasks. In this talk I will focus on discrete linear problems: giving a general overview of the well-established class of solvers called Krylov subspace methods and its regularizing properties; as well as recent developments that make them suitable to solve more challenging optimization tasks. I will show results and examples in different imaging applications. This talk is part of the Optimisation and Numerical Analysis Seminars series. This talk is included in these lists:
