Prof. Dr. Matthias Feurer

About

I am a Thomas Bayes Fellow and interim professor at the Chair of Statistical Learning and Data Science funded by the Munich Center for Machine Learning.

With my research, I aim to simplify the usage of machine learning by researching methods and developing tools that allow the usage of machine learning by domain scientists and also make machine learning more efficient for expert users. My focus is on Automated Machine Learning (AutoML) which encompasses methods for hyperparameter optimization, meta-learning, and model selection. However, machine learning is not solely about predictive performance but also about additional objectives such as model interpretability, deployability, or fairness. For this, I want to move beyond performance-driven machine learning by applying multi-objective AutoML.

Furthermore, I am developing and contributing to multiple open-source projects in the realm of AutoML (see below) and am a co-founder of the Open Machine Learning Foundation that supports the development of OpenML.org.

Short Bio

Since April 2023, Matthias Feurer is a Thomas Bayes Fellow and interim professor, funded by the Munich Center of Machine Learning (MCML). He is a member of the Chair of Statistical Learning and Data Science (Department of Statistics, LMU Munich), which is headed by Prof. Dr. Bernd Bischl. Previously, he was a PostDoc at the machine learning lab at the Albert-Ludwigs-Universität Freiburg, where he also finished his PhD under the supervision of Prof. Dr. Frank Hutter on the topic of Automated Machine Learning. Before that, he studied Computer Science at the University of Freiburg (M.Sc.) and Computer Science and Media at the Media University Stuttgart (B.Sc.).
