Tutorial Schedule (Monday)

Speaker/Poster Schedule (Tuesday – Friday, 6th floor Ballroom)

DCLDE Workshop sessions include contributed talks and a dedicated discussion period moderated by the session chair and co-chair.  We’ll be looking to make maximum use of our virtual meeting platform to bring in discussion from in-person and online participants.  Most in-person presentations will present their work live. Virtual attendees will provide a pre-recorded talk and will be onscreen live for questions immediately after their talk and during the discussion period. Virtual presenters, or online co-authors of live presenters, are encouraged to watch the online chat during their talks to engage with questions and comments.   

Presentation uses one of the DCLDE datasets to develop, test, or validate the presented approach
