PRL Workshop – Bridging the Gap Between AI Planning and Reinforcement Learning

Planning and Reinforcement Learning workshop

Bridging the Gap Between AI Planning and Reinforcement Learning (PRL @ ICAPS) – Workshop at ICAPS 2022 (June 13)

This site presents the most up-to-date information about the PRL @ ICAPS workshop. Please, visit ICAPS 2022 for information about the general conference.

NEWS: This year the PRL workshop will have two editions: The first one at ICAPS 2022, and the second one at IJCAI 2022. PRL@ICAPS authors will be given the opportunity to specify whether they want their submission to be considered for PRL@IJCAI as well. The final decision will be made separately for each of the workshop locations. Please see the website for additional information on the two editions.

While AI Planning and Reinforcement Learning communities focus on similar sequential decision-making problems, these communities remain somewhat unaware of each other on specific problems, techniques, methodologies, and evaluation.

This workshop aims to encourage discussion and collaboration between the researchers in the fields of AI planning and reinforcement learning. We aim to bridge the gap between the two communities, facilitate the discussion of differences and similarities in existing techniques, and encourage collaboration across the fields. We solicit interest from AI researchers that work in the intersection of planning and reinforcement learning, in particular, those that focus on intelligent decision making. As such, the joint workshop program is an excellent opportunity to gather a large and diverse group of interested researchers.

Workshop topics

The workshop solicits work at the intersection of the fields of reinforcement learning and planning. One example is so-called goal-directed reinforcement learning, where a goal must be achieved, and no partial credit is given for getting closer to the goal. In this case, a usual metric is success rate. We also solicit work solely in one area that can influence advances in the other so long as the connections are clearly articulated in the submission.

Submissions are invited for topics on, but not limited to:

Submission Procedure

We solicit workshop paper submissions relevant to the above call of the following types:

Please format submissions in AAAI style (see instructions in Author Kit 2021 at AAAI, http://www.aaai.org/Publications/Templates/AuthorKit22.zip). Authors considering submitting to the workshop papers rejected from other conferences, please ensure you do your utmost to address the comments given by the reviewers. Papers accepted to the main ICAPS conference may be considered in the extended abstract form.

Some accepted long papers will be accepted as contributed talks. All accepted long and short papers and extended abstracts will be given a slot in the poster presentation session. Extended abstracts are intended as brief summaries of already published papers, preliminary work, position papers or challenges that might help bridge the gap.

As the main purpose of this workshop is to solicit discussion, the authors are invited to use the appendix of their submissions for that purpose.

Paper submissions should be made through EasyChair.

Please send your inquiries by email to the organizers at prl.theworkshop@gmail.com.
