3. Rao’s Gripe Festivus 1 Recap A couple of things I want to say

5. Our Best Feat so far..

6. Balance sheet from the First Festivus Let’s increase the general levity in the community (Rao) –Done (have you seen Jorge’s talks lately. The guy is a regular Seinfeld now?) Let’s have double-blind reviewing (Martha) –Done Let there be kindness & light in reviewing (Dave) –Working on it. Let 100 birds sing (Amedeo) –Done (although they are singing in Italian and we can’t make out what they are singing about..) Let’s stop accepting Rao’s poster papers (Craig) –Done (we are accepting them all as presentations) Let’s work on “real world applications” (Dan & Adele) –You kidding?

8. And this is the guy who seemed to believe that only plan graphs should relax..

14. Where have all our hard problems gone? We have too many smart humans in the field… May be we should look for the really hard problems in each track –Toughnuts –Required concurrency –Probabilistically interesting ….but then I wonder…

Underlying System Dynamics Classical Temporal Metric Metric- Temporal Non-det PO Stochastic Traditional Planning PSP Planning Optimization Metrics Any (feasible) Plan Shortest plan Cheapest plan Highest net-benefit Multi-objective [AAAI 2004; ICAPS 2005 IJCAI 2005; IJCAI 2007] Model Completeness Full Approx Shallow Model-lite Planning Incomplete Dynamics OR user preferences

17. (Gently) Questioning the Assumption There are many scenarios where domain modeling is the biggest obstacle –Web Service Composition Most services have very little formal models attached –Workflow management Most workflows are provided with little information about underlying causal models –Learning to plan from demonstrations We will have to contend with incomplete and evolving domain models....but our techniques assume complete and correct models.. The way to get more applications is to tackle more and more expressive domains

19. Model-Lite Planning is Planning with incomplete models..“incomplete”  “not enough domain knowledge to verify correctness/optimality” How incomplete is incomplete? Missing a couple of preconditions/effects or user preferences? Knowing no more than I/O types? http://rakaposhi.eas.asu.edu/model-lite From “Any Time” to “Any Model” Planning

20. Challenges in Realizing Model-Lite Planning 1.Planning support for shallow domain models 2.Plan creation with approximate domain models 3.Learning to improve completeness of domain models

21. Challenges in Realizing Model-Lite Planning 1.Planning support for shallow domain models [ICAC 2005] 2.Plan creation with approximate domain models [IJCAI 2007, ICAPS Wkshp 2007] 3.Learning to improve completeness of domain models [ICAPS Wkshp 2007]

22. Summary While model-intensive planning continues to have a place (e.g. NASA), we should also look at model-lite planning –Applications include workflows, web services, desktop automation, collaborative learning/planning The aim is to reduce modeling burden. –Either by reducing planning support (shallow domain models) –or by increasing the plan creation cost (approximate domain models) The challenges in each are different.. Learning goes hand-in-hand with planning in model-lite planning scenarios. http://rakaposhi.eas.asu.edu/model-lite From “Any Time” to “Any Model” Planning
