The seminar will take place Wednesdays 09:15-10:45 in G29-E037. The first introductory session starts on October 28. Here we discuss possible topics and start the process of allocating these projects and topics to you. Starting mid December we plan to have first presentations of projects and talks.

Due to Covid-19 we will have to be flexible and will organize the seminar in a hybrid fashion. All online parts as well as broadcasts of sessions at the University will happen in the seminar's Zoom channel.

We kindly ask you to read and acknowledge the Corona guidelines of the University

This seminar is a joint event of the faculties for computer science and mathematics. Students will give talks or present projects on different mathematical and numerical aspects of deep neural networks used for physical simulations. The focus can either be on the presenation of the underlying mathematical theory or on the implementation of approaches and a demonstration and ciritical discussion of the results.
