  3. Premise • 25 years ago, most AI researchers were motivated by goals of “human-level” AI • Since then • scope has narrowed to problems that are both more feasible and more practical • we have developed a large body of technical tools and sounder theoretical and experimental methodology

  4. Questions • Are we ready to go back and try to do human-level AI? • Do our new tools and techniques put us in a better position than we were in before? • Are there other “big AI” goals we should be aiming at? • What challenge problems would help us address these questions? • Note: these problems weren’t designed to be necessarily amenable to competitions or short-term evaluation, but to stretch us scientifically

  5. Challenge-problem Desiderata • Graded series of problems • Whole problem should force a general solution • Integration of • perception • communication • action • Involvement of learning • Difference of opinion: • focus on human-level AI; “whole agents” • focus on super-human tools

  6. Four HLAI Problems • Real robot • Simulated robot • Trading agent • Office assistant

  7. Robot Cook • Make breakfast in any kitchen • Short order cook • perception and manipulation • cultural expectations about locations of things • time pressure and flexibility

  8. Simulated Robots • Disaster relief • New environment you have not seen before • Exploration and mapping; putting out fires, dealing with other threats • Time-critical; competing goals; novel situations; tasked by controller, but not centrally controlled • Robocup rescue simulator?

  9. Automated Trading Corporation • Exists on the web • Negotiates contracts • Insurance contract (no prior stake in order to evaluate) • How do you write contracts • insurance • guarantees of credit

  10. Office Assistant • Reads your office documents (mail, ppt, etc) • Listens to and watches your meetings • Carries out tasks for you: • purchasing • filing • travel planning • Takes initiative to remind you of things, reschedule meetings, etc. • System has to model human’s state of mind

  11. Big-picture, Non-human AI • Leverage the way the world is changing around us; and help to change it • new sources of social interaction data • new sources of scientific data • interesting opportunities in these areas • how people interact with technology

  12. Cognitive Google • Tell me about “shape matching in proteins” • Look for people who might have written down something interesting about that topic. • “find someone who had been to Barcelona of my age and my interest” • Community of Intelligent research assistants

  13. High-level Perception • Learn to describe complex scenes in natural language and answer questions about them • Example: observe someone assembling a piece of furniture. Then be able to show someone else how to do the same (or similar) assembly tasks. • Example: recognize when someone is taking out cash from an ATM. Generalize to all ATMs. • Watch TV: • Infer plans + goals from video • Write soap-opera summaries • Describe sports events

  14. Not Easy! • All of these problems are very hard • Simple versions can be made • They will focus our long-term thinking
