What to expect
The DRPS Course Descriptor provides an overview of the course and its requirements. For general information on the different machine learning courses at Informatics, see here. Further have a look at the lecture slides and tutorials from the last edition of PMR. They should give you an idea about the course.
The course covers foundational material in machine learning and provides you with tools and skills to understand many different methods and develop new ones. But this also means that the course is generally more theoretical and mathematical than the other machine learning courses at Informatics (e.g. IAML, MLP, or MLPR). It will feature more pen and paper work than programming and is not an applied course. If you took MLPR and found the math and theory aspects difficult or not interesting, you will likely not enjoy PMR.
