The event is open to ELLIS PhDs and postdocs, as well as PhDs of ELLIS Fellows/Scholars/Members, but is limited to 150 participants. The organizers will prioritize active members of the ELLIS network, and students who are early in their PhDs. A small number of slots will be reserved for other EU ICT-48 projects' students. Participants are expected to present a poster or prepare a tooling session with a strong machine learning component. The topic of the poster or tooling session is completely open, as the ELLIS Programs bring together researchers from multiple disciplines within the Machine Learning community (Computer Vision, NLP, Theoretical ML, Reinforcement Learning, Human-Centric ML…).
