In the second semester of 2022-2023, I teach the class on Foundations of Statistics and Machine Learning (detailed course information available via bright space; if you are not a Leiden student and still want to attend the class, contact me). This is the third year in which I teach this class; before that I thought, for many years, a class on information-theoretic learning at Leiden University (course webpage)  and I also thought, with group members Wouter Koolen and Rianne de Heide, a mastermath course on Machine Learning theory (now this course is given by Tim van Erven and Wouter Koolen). Mastermath is the joint Universities National Dutch Master’s Programme in Mathematics. In an earlier life I tought a class on Statistical Learning for the Leiden Master of Statistical Science for the Life Sciences.
