Maximilian Thiessen

PhD student in machine learning

TU Wien

Hi!

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.

Interests
  • Machine Learning
  • Active Learning
  • (Metric) Graph Theory
Education
  • PhD in Computer Science, 2020 — Present

    TU Wien, Austria

  • MSc in Computer Science, 2020

    University of Bonn, Germany

  • BSc in Computer Science, 2017

    University of Bonn, Germany
