A Summary of Previous Grand Challenge Proposals for Cognitive Systems

The notion of a Grand Challenge (GC) in computational cognition is not new. It has been addressed both specifically and in the context of Grand Challenges in computing as a whole. One well-known example, DARPA's Autonomous Vehicle Grand Challenge (AVGC), has captured the imagination of the media and the public. The AVGC is much more than a compelling research goal or a way to make DARPA's work relevant to the average layperson; it is a measurable test which can tell us where to focus our work and how much we have accomplished. The AVGC has "raised the bar" for what it means for a Grand Challenge to set the agenda for a field of research.
