After finishing his Master's thesis about machine learning methods applied to the discrimination between atrial fibrillation (AFib) and regular atrial arrhythmias including atrial flutter (AFlu), Felix Bernhardt started in January to work as a PhD student in our working group and continues to do research in the intersection of machine learning and optimization applied to medical applications. Later on in 2019, Alexander Ryzhkov and Anna Gebhard joined our group as PhD students. Alexander has research interests in global optimization, in particular lifted Newton approaches, while Anna works on mathematical modeling and optimization of acute myeloid, resepctively lymphoblastic, leukaemia.
Emily Speakman accepted an assistant professor position at the University of Colorado, Denver so that she left the work group after roughly two successful years as a PostDoc.
Several theses were successfully defended: Stephan Große (Optimale Portfoliosteuerung mit stochastischen Parametern), Johanna Kreuzburg (Die Anwendung von Bayesian Learning im Rahmen der Investitionsbewertung unter Unsicherheit), Paul Scharnhorst (Optimal Control Methods for Deep Learning), and Jan David Schneider (Geometric Methods in Dynamic Averaging for Decentralized Deep Learning) obtained a Master and Christoph Plate (Approximation der Überlappungswahrscheinlichkeit zweier Rechtecke mittels neuronaler Netze) and Adrian-Manuel Reimann (Feature Selection mittels Support Vector Machines zur medizinischen Diagnostik von Schlafapnoe), obtained a Bachelor degree.
At the beginning of the year our group retreat to Garmisch-Partenkirchen took place. We spent a week in the cute alpine town, where we found time for skiing and snowboarding but also had the opportunity to discuss different research questions in project work.
In October we had an opening party for the new common room G02-210, combined with an "Mathenachtstraum 2019" event. The room has been completed after a long planning and implementation phase and is designed to fulfil various functions. As a meeting, break and conference room for all staff of the faculty, as a meeting room for, among others, the faculty council and also as a lecture room for special events. As part of the "Mathenachtstraum 2019" the filmmaker and mathematician Ekaterina Eremenko presented her latest film "Head Heart and Soul" which is - roughly speaking - about modern math lectures interpreted by modern artists, here you can find a trailer.
In 2019 the members of the MATHOPT group joined several conferences and presented new research results. Two highlights:
