ICAPS'22 Workshop on Reliable Data-Driven Planning and Scheduling

An ICAPS'22 Workshop
Singapore Online
June 17, 2022

Data-driven AI is the dominating trend in AI at this time. From a planning and scheduling perspective – and for sequential decision making in general – this is manifested in two major kinds of technical artifacts that are rapidly gaining importance. First, planning models learned from data, or partly learned from data (such as e.g. a weather forecast in a model of flight actions). Second, action-decision components learned from data, in particular, action policies or planning-control knowledge for making decisions in dynamic environments (such as e.g. manufacturing processes under resource-availability and job-length fluctuations). Given the nature of such data-driven artifacts, reliability is a key concern, prominently including safety, robustness, and fairness in various forms, but possibly other concerns as well. Arguably, this is indeed one of the grand challenges in AI for the foreseeable future.

Given this, the workshop welcomes contributions to any topic that roughly falls into the following problem space:

  • Data-driven artifacts: Reliability of learned planning and scheduling models (e.g. action models, transition probabilities, environment prediction, etc.); learned action-decisions (e.g. action policies, components thereof, previous plans, etc.); combinations of both.
  • Objectives: Reliability in whatever form, including risk, safety, robustness, fairness, error bounds, etc.; alongside possibly other concerns such as scalability and data efficiency, system design/engineering principles and challenges, and the interactions of these with reliability.
  • Methodologies: Planning and scheduling algorithms in the presence of learned artifacts as per 1.; analyzing such artifacts (reasoning, verification, testing, etc.); making such analyses amenable to human users (visualization, interaction); potentially others as relevant to the objectives as per 2.

Submission Information

All papers must be formatted according to the AAAI formatting guidelines. Paper submission is via EasyChair:

We call for two kinds of submissions:

  • Technical papers, of length up to 8 pages plus references. The workshop is meant to be an open and inclusive forum, and we encourage papers that report on work in progress.
  • Position papers, of length up to 4 pages plus references. Given that reliability of data-driven planning and scheduling is rather new at ICAPS, we encourage authors to submit positions on what they believe are important challenges, questions to be considered, approaches that may be promising. We will include any position relevant to discussing the workshop topic. We expect to group position paper presentations into a dedicated session, followed by a panel discussion.

Please do not submit papers that are already accepted for the main conference. All other submissions, e.g. papers under review for IJCAI'22, are welcome. Authors submitting papers rejected from the main conference, please ensure you do your utmost to address the comments given by ICAPS reviewers. Also, it is your responsibility to ensure that other venues your work is submitted to allow for papers to be already published in "informal" ways (e.g. on proceedings or websites without associated ISSN/ISBN).

Every submission will be reviewed by members of the program committee according to the usual criteria such as relevance to the workshop, significance of the contribution, and technical quality.

At least one author of each accepted paper must attend the workshop in order to present the paper. The workshop format (fully virtual or hybrid) will be the same as the format of the main conference. Authors must register for the ICAPS conference in order to attend the workshop.
