- For a nice python example on the PCA see here.
- Mark Embree (Virgnia Tech) talking about the DEIM CUR.
- Please register for your group in OPAL.
- Gil Strang (MIT) talking about randomization in NLA here.
- For the exam you will be handed a sheet with short quesitons and a programming task for which you will have 30 minutes to prepare. We provide a laptop with Python. Please arrive 30 minutes before your exam. Additional questions in the exam could look like the following here.

Add the course to your own schedule via
- The exercise sheets will be Jupyter notebooks. We will work on them together during the exercise time.
- You can use the pool computers or your own devices. The computations will be handled by the faculty Jupyter Hub.
- You do not have to use the Jupyter Hub, but we cannot provide any assistance if you decide to run Jupyter and Conda locally.
- Every exercise will have (at least) a mandatory part which may be relevant for the exam. In some cases there will be an optional part that you can work on in your spare time.
- The sheets will be available in OPAL.
- The exam will consist of a 30-minute oral exam with preparation time beforehand.
