Integrated Execution (IntEx) / Goal Reasoning (GR)

COVID-19 Update Please note revised timeline for submissions.

Automated planners are increasingly being integrated into online execution systems.  The integration may, for example, embed a domain-independent temporal planner in a manufacturing system (e.g., the Xerox printer application) or autonomous vehicles.  The integration may resemble something more like a “planning stack” where an automated planner produces an activity or task plan that is further refined before being executed by a reactive controller (e.g., robotics).  Or, the integration may be a domain-specific policy that maps states to actions (e.g., reinforcement learning). Online learning may or may not be involved, and may include adjusting or augmenting the model, determining when to repair versus replan, learning to switch policies, etc.  A specific focus of these integrations involves online deliberation, bringing to the foreground concerns over how much computational effort planning should invest over time.  

Goal reasoning systems often assume an online planning paradigm.  An important aspect of integrated planning and acting systems is the ability to deal with a variety of situations that may arise online. A fundamental premise of goal reasoning is reconsidering goals that may no longer be relevant as situations evolve. While some work has been done on goal reasoning capabilities in integrated planning and acting systems, there is still no consensus about how a system should monitor and progress goals during execution.  

This combined 4th Integrating Planning, Acting, and Execution (IntEx) and 8th Goal Reasoning (GR) workshop aim to bring together researchers from these subfields to encourage cross-disciplinary discussion on the challenges of integrating planning with execution, emphasize the role of goal reasoning, raising awareness, promoting discussion, and encouraging cross-fertilization of ideas.

Topics

Following from the IntEx series, we welcome papers on past topics of interest including benchmarks or challenge problems for integrated execution; improving planning performance from execution experience; plan dispatching or plan executives; anytime or incremental planning; execution monitoring, comparing online planning approaches or plan merging; managing open worlds with closed-world planners; model learning from experience or determining an observation policy; policy switching or applying incremental policy adjustment.  

As part of the special focus on Goal reasoning, we specifically welcome papers from: 

Foundations of Goal Reasoning:

  • Theoretical models of goal reasoning or comparisons to other models of autonomy
  • Studies of implicit goals or goal reward/value functions
  • Goal management: including formulation, selection, or optimization
  • Integrating planning or metareasoning with goal management
  • Online goal resolution (e.g., plan repair, replanning, goal deferment, re-goaling)
  • Learning, evaluation, or analysis of goal reasoning systems

Goal Reasoning Systems

  • Goals in self-motivated systems, hybrid systems, Belief-Desire-Intention systems, or Goal-Driven Autonomy
  • Multi-agent or distributed goal management
  • Demonstrations or applications of goal reasoning systems

Human Interaction & Goal Reasoning

  • Interactive goal reasoning, human-machine goal reasoning, or social goal reasoning
  • Conversational or narrative reasoning about goals
  • Explanation and diagnosis of notable objects or events impacting goals

Important Dates

  • Paper submission:  July 31st (Submissions are open).
  • Notification of acceptance/rejection: August, 31st.
  • ICAPS Early registration: TBD.
  • Workshop date: October 21st/23rd.

Submission Instructions

Submissions may be regular papers (up to 8 pages plus references) or short position/challenge papers (up to 4 pages plus references). All papers should conform to the AAAI formatting guidelines and style (https://www.aaai.org/Publications/Templates/AuthorKit20.zip). The submissions do not need to be anonymous (reviewing will *not* be anonymous).

The papers must be submitted in a PDF format via the EasyChair system (https://easychair.org/conferences/?conf=intex2020) Submissions will be reviewed by at least two referees.

We welcome existing publications from other venues that are appropriate for discussion at this workshop. If the work is under review at another venue (e.g., IJCAI-2019), the manuscripts should be submitted anonymously for a double-blind reviewing process. 

At least one author of each accepted paper must attend the workshop in order to present the paper. The authors must register for the ICAPS main conference in order to attend the workshop. There will be no separate workshop-only registration.
