From October 21 to October 23, the biannual gathering of KD2School took place at the Industrie-Club in Bremen. Participants not only learned about the progress of the DFG-funded research training group and associated young researchers, they also gained valuable insights through a keynote titled “Ideas of Tools and Teammates - On Human-Machine Relations in Contemporary Digitalization Research“ given by Prof. Benjamin Müller. As part of the retreat, the workshop "Machine Learning meets Biosignals" was also offered by Prof. Martin Mundt and Dr. Felix Putze.
