Learning Outcomes

The main objective of this lecture series is to give students working knowledge on a broad class of Mann-type iterative algorithms in Hilbert spaces, with focus on projection-based methods. These algorithms have been used to solve diverse problems in science and engineering such as interference reduction in MIMO systems, adaptive beamforming, peak-to-average-power-ratio (PAPR) reduction in OFDM systems, acoustic source localization, environmental modeling in wireless multi-agent systems, radio map reconstruction, and machine learning, to name a few. In the initial lectures, we start by giving students the necessary background on real Hilbert spaces and their connection to more general spaces. Students are then exposed to convex feasibility problems and vector space projection methods, and we illustrate as often as possible the mathematical concepts with concrete, real-world applications in wireless communications and signal processing. The final lectures have the objective to introduce students to fixed point algorithms based on Mann-type iterations. In the second track of lectures the students will develop a solid understanding of theoretical foundations of Machine Learning and will be able to develop, apply, and analyse the complexity of the resulting learning algorithms. A special emphasis will be put on methods for construction of efficient learning algorithms. E.g. Empirical risk minimisation via linear programming and ideas based on perceptron algorithms, stochastic subgradient methods, and support vector machines.


The learning content includes: 1. Introduction and outline of the course 2. Metric spaces; Vector spaces; Normed vector spaces and Banach spaces; Inner products and real Hilbert spaces 3. Basics in convex analysis: convex sets, projections and relaxed projections, the fundamental theory of POCS, parallel projection methods, applications (interference reduction in communication systems, acoustic source localization with wireless sensor networks, estimation tasks in massive MIMO systems, kernel machines in sensor networks) 4. Selected topics in quasi-nonexpansive operator theory. Mann-type iterative algorithms. 5. Splitting methods for convex optimization (forward-backward splitting methods, proximal/projected gradient methods, etc.) 6. Model of learning, loss functions, and losses/risks. 7. Stochastic inequalities and concentration of measure 8. Uniform laws of large numbers, Rademacher complexity, and learning via uniform convergence. 9. Vapnik-Chervonenkis dimension and bounds on sample complexity 10. Support vector machines and kernel methods. 11. Stochastic subgradient algorithms.
