IAM664 - Inverse Problems

Credit: 3(3-0); ECTS: 8.0
Instructor(s): Gerhard-Wilhelm Weber
Prerequisites: Consent of instructor (Basic knowledge in numerical and statistical methods and, if possible, in probability theory)

Course Catalogue Description

Classification of inverse problems, linear regression, discretizing continuous inverse problems, rank-deficiency, Tikhonov regularization, iterative methods, other regularization techniques, Fourier techniques, nonlinear inverse problems, Bayesian methods. Computer applications and MATLAB exercises are important elements of the course.

Course Objectives

  • The objective of this course is to promote fundamental understanding of parameter estimation and inverse problems methodology, specifically regarding such issues like uncertainty, ill-posedness, regularization, bias and resolution using examples from various fields of applications, e.g., engineering, financial mathematics, economics, the environmental sector, Operational Research, computational biology and social sciences.

Course Learning Outcomes

  • At the end of the course, students should have a good overview of modern scientific methods in inverse problems. They should also be able to choose and work them out appropriately in contexts of project applications and of their theses.
