Regular Submission Instructions

Regular submissions may be research or position papers. All submissions are handled through OpenReview and must be anonymized for double-blind review. Papers should be no more than 10 pages (excluding references) and follow the Overleaf template adapted from ICLR. An optional appendix of any length may be included at the end of the draft after the references.

Our workshop does not have formal proceedings, i.e., it is non-archival. Accepted papers and their review comments will be posted on OpenReview in public (after the end of the review process), while rejected and withdrawn papers and their reviews will remain private.

We welcome submissions presenting novel research, ongoing or incomplete projects, manuscripts currently under review at other venues, as well as recently published results. In addition, we adopt the following policies:

• [Submission on previous conference papers] We allow submissions that have been accepted at major machine learning conferences within one year of ICLR 2026 (i.e., after May 2025), including papers recently accepted to the ICLR 2026 main conference. However, as workshops are primarily intended to showcase novel or ongoing research, submissions based on previously published work may be deprioritized for oral presentations.
• [Submission on previous journal papers] For work published in journals, we leave it to the authors to assess the novelty and relevance of the submission for the community. While the machine learning field moves quickly, this workshop aims to be inclusive of subareas that may progress at a different pace and values contributions that emphasize fundamental and long-lasting research.

Short Paper Submission Instructions (3–5 pages)

Since 2025, ICLR has discontinued the separate “Tiny Papers” track, and is instead requiring each workshop to accept short (3–5 pages in ICLR format, exact page length to be determined by each workshop) paper submissions, with an eye towards inclusion; see https://iclr.cc/Conferences/2025/CallForTinyPapers for a history of the ICLR tiny papers initiative. Authors of these papers will be earmarked for potential funding from ICLR, but need to submit a separate application for Financial Assistance that evaluates their eligibility. This application for Financial Assistance to attend ICLR 2026 will become available on https://iclr.cc/Conferences/2026/ at the beginning of February and close early March.

Building on last year's practice, our workshop continues to welcome short paper submissions intended to support underrepresented, under-resourced, and early-career researchers who may not yet have the means to submit full papers. This track is intended for work at the early stages of a project: for example, a concise but self-contained theoretical result, a novel observation from preliminary experiments, or a fresh perspective on an existing problem. The goal is to foster early-stage ideas and provide a platform for researchers to receive constructive feedback and guidance as they develop their work further.

Short papers will be peer reviewed. Submissions should be anonymized, 3–5 pages long (excluding references), using the same submission portal in OpenReview and following the same Overleaf template . In addition, please clearly add a tag [Short] at the beginning of the submission title.

In accordance with ICLR policy, AI-generated papers are not permitted in the short paper track.

Author-Reviewer Policy

The workshop program committee plays an important role in identifying and giving feedback on up-and-coming work that would most benefit from discussion and visibility at the workshop. To sustain our review and program selection processes, we expect at least one author of each submitted paper to volunteer to participate as a reviewer for the DATA-FM 2026 workshop.

Large Language Model Usage Policy

DATA-FM 2026 adheres to the ICLR 2026 policies on large language model (LLM) usage: https://blog.iclr.cc/2025/08/26/policies-on-large-language-model-usage-at-iclr-2026/.

In particular, authors may use LLM-based tools to assist with writing, editing, coding, or experimentation, provided that any such use is disclosed, and that all human authors take full responsibility for the content and originality of the submission.
