W3-Professor for "Foundations of Machine Learning Systems" at the Eberhard Karls University Tübingen, Faculty of Mathematics and Natural Sciences
Research Interests
Bob Williamson is interested in understanding and designing machine learning systems as a whole. To that end he is pursuing theoretical questions regarding machine learning problems and how they relate to each other, including information theoretic limits of performance; the connections between information theory and societal challenges in machine learning (such as fairness); as well as developing new approaches to the overall architecture of machine learning systems that support trustworthiness and reliability in their use.
The Key Notions of Foundations of Machine Learning Systems: 1. Atoms of ML regarding the relationship between information and utility. 2. Data as process. 3. Context of data in ML. 4. Models of Uncertainty, how they are represented and the implication of different choices. 5. Rhetoric of ML and how it can be shaped to deal with all the points listed above. 6. Relations between ML problems to better illustrate the nature of ML problems. 7. Tradeoffs, especially between the notions of utility and ethics.
