Competencies / intended learning achievements

Upon successful completion of this module, the students have studied and understand fundamental methods and propositions of the theory of Riemannian manifolds. They are familiar with first-order optimization and descent methods on manifolds. They have learnt important examples of manifolds and gained an impression of the role of manifolds in the context of image processing and data analysis. They understand the mathematical background of the algorithms and are able to analyze them and to apply them to concrete questions. They understand the proofs presented in the lecture and are able to comprehend and explain them. In particular, they are able to outline the conditions and assumptions that are necessary for the validity of the statements.

By completing the given exercises, the students have developed a skilled, precise and independent handling of the terms, propositions and techniques taught in the lecture. Moreover, they have performed implementations for the application of the algorithms in image processing.
