Dear colleagues,
We are excited to invite submissions to the NeurIPS 2025 Workshop on "ML×OR: Mathematical Foundations and Operational Integration of Machine Learning for Uncertainty-Aware Decision-Making", which will be held in person on December 6 or 7 in San Diego as part of the NeurIPS 2025 conference. You can find detailed information in the workshop website: https://mlxor-workshop.github.io/ , and it will be regularly updated as more details are finalized.
This interdisciplinary workshop explores the growing synergy between Machine Learning (ML) and Operations Research (OR). As the first NeurIPS workshop explicitly themed on ML-OR synergization, it aims to present recent developments, discuss challenges, and publicize emerging research opportunities in data-centric decision-making that leverage both the rapid advancement of ML and the principled methodological rigor of OR. We welcome a broad range of contributions in the ML-OR intersection.
Workshop Themes and Format
Topics of interest include (but are not limited to):
-
Embedding OR modeling insights into ML
-
Uncertainty mitigation at the interface of data, model, and decision
-
Sequential decision-making and online learning from an OR perspective
-
Generative AI for decision-making
We encourage submissions from researchers across ML, OR, applied probability, and statistics, as well as practitioners from industry and public sector organizations. We especially encourage submissions that propose new methodologies, offer theoretical insights, or present real-world applications in areas such as healthcare, logistics, finance, and energy systems.
In addition to the poster session and presentation of accepted submissions, the workshop will feature several keynote talks, panel discussions, and plenty of opportunities to interact among participants.
We also plan to provide financial support for students and junior researchers who contribute to the workshop, via INFORMS Applied Probability Society and potentially other sponsors. More details on the application procedure will be available soon.
Paper Submission
Submissions are limited to at most 4 pages of main body, in the NeurIPS conference proceedings format (please see https://neurips.cc/Conferences/2025/CallForPapers). In addition to these 4 pages, references of an unlimited length are allowed.
Submissions are non-anonymous and non-archival. We welcome submissions based on preliminary working progress, work under review, or work that has already been published in prior venues. In particular, papers based on work under review or prior publication are allowed and encouraged.
For papers based on preliminary working progress, submission to the workshop will not preclude future journal or conference publication. Moreover, these papers will have the option to be considered for fast-track submission of the full-length version to Stochastic Systems, the flagship journal of INFORMS Applied Probability Society.
All accepted papers will be presented in an elaborate poster session at the workshop. In addition, several selected papers will be chosen as "spotlight" for oral presentations.
Submissions should be made via OpenReview: https://openreview.net/group?id=NeurIPS.cc/2025/Workshop/MLxOR
Submission Deadline: September 5, 2025 (Anywhere on Earth)
Notification of Acceptance: By September 22, 2025
Workshop Date: December 6 or December 7, 2025
If you have any questions or would like additional information, please feel free to reach out to us via: neurips.mlxor.workshop@gmail.com .
Please feel free to share this call with your colleagues and collaborators.
We look forward to your submissions and hope to see you in December at NeurIPS 2025!
