Requisites: Before taking this module you must take MA50174 OR take MA50178 OR take MA50281 or equivalent.
Learning Outcomes: By the end of this unit, you will be able to
  • formulate inverse problems and understand the importance of regularisation,
  • construct, analyse, and interpret solutions to inverse problems for a range of applications;
  • apply statistical filtering methods and interpret their solutions.

Aims: To understand inverse problems and their importance in many areas of science, and to develop theoretical and practical understanding of data assimilation, filtering, and regularisation methods for solving inverse problems.

Skills: Problem solving (T, F&A), computing (T, F&A), written and oral communication (F&A).

Content: Inverse problems; ill-posedness and regularisation methods, Tikhonov regularisation and truncated singular value decomposition. Variational regularisation.
Statistical data assimilation and filtering; variational methods (3DVar/4DVar); Kalman filters.
Applications, for example, in medical imaging, meteorology and oceanography.
