I'm the Head of the Machine Learning Lab. I'm lucky enough to have an amazing team; all my team members are linked in the sidebar on the left. In addition to my full-time role at the University of Freiburg, I also consult for the Bosch Center for AI (BCAI) as Chief Expert for AutoML.

General research interests

I am interested in all facets of intelligence, and how we can replicate it in artificial systems. In particular, I work on
  • Statistical machine learning (in particular deep learning), to learn effective representations for large amounts of very noisy data (including uncertainty quantification)
  • Automated problem solving, including knowledge representation
  • Autonomously-learning software systems, which can improve their performance over time without the need for a human in the loop
  • Sequential decision making under uncertainty, to trade off building better models of the world vs. acting better based on them
  • Scientific experimentation, to make empirical research more reproducible and to codify human experts' strategies to the point where an autonomous system can execute them.
Most of my research is of a methodological nature on the meta-level, such as machine learning methods that model & optimize the performance of other machine learning methods. These meta-level problems constitute a great `drosophila' for AI: they require representation learning, reasoning under uncertainty, bounded rationality, active learning, exploration/exploitation tradeoffs, transfer learning, and much more, but they also allow for a perfectly reproducible environment with complex dynamics and available ground truth (given enough computational power). Also, they are great from a practical perspective since their outputs are better algorithms for problems we care about.

Specific research areas

I currently focus on a few research areas that combine the general themes above:
  • Bayesian optimization -- sequential experimental design under uncertainty
  • Automated machine learning -- developing an AI that can compete with human data scientists
  • Deep learning -- automatically learning representations of the data; in particular, I work on automating structure & hyperparameter search for deep learning, and on improving optimization algorithms for deep networks
  • Automated algorithm design -- developing automated methods for parameter optimization, algorithm selection, and algorithm analysis. A few years ago, I gave a Google tech talk on this topic; you can watch it on youtube.

Affiliations

I'm a member of the Department of Computer Science at the Faculty of Engineering of the University of Freiburg. In addition to my full-time role at the University of Freiburg, I also consult for the Bosch Center for AI (BCAI) as their Chief Expert for AutoML. I hold an ERC Starting Grant from the European Research Council and an Emmy Noether Grant from the German Research Foundation (DFG). I'm a former member of the Computer Science Department of the University of British Columbia (UBC), specifically of the Laboratory for Computational Intelligence (LCI) and the Bioinformatics and Empirical & Theoretical Algorithmics Laboratory (BETA). I was a machine learning consultant for Zynga Inc and am a co-founder of Meta-Algorithmic Technologies. I earned my PhD at UBC in 2009 and my Diplom (eq. MSc) at Darmstadt University in 2004.

I will be program co-chair of ECML 2020 in Ghent. I co-founded and regularly co-organize the NeurIPS workshop series on meta-learning and the ICML workshop series on AutoML. I also co-founded and regularly co-organized the NeurIPS workshop series on Bayesian optimization. Please see http://automl.org/workshops for an up-to-date list of workshops I'm co-organizing.
