Maximilian Thiessen

PhD student in machine learning

TU Wien


Hey, my name is Max. I am a PhD student supervised by Prof. Thomas Gärtner in the machine learning research unit at TU Wien, Austria. Before that, I studied computer science at the University of Bonn under the supervision of Dr. Tamás Horváth. My main research interest is active and semi-supervised learning. The goal is to achieve novel sample and query complexity bounds for learning tasks on graphs using convexity theory. Additionally, I am working on graph representations that go beyond the Weisfeiler-Leman isomorphism test.
