Submission Instructions

Submissions should be double-blind, no more than 6 pages long (excluding references), and following the ICLR'25 template. An optional appendix of any length can be put at the end of the draft (after references).

Submissions are processed in OpenReview.

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their review comments will be posted on OpenReview in public (after the end of the review process), while rejected and withdrawn papers and their reviews will remain private.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 sumbissions from novel research, ongoing (incomplete) projects, draft currently under review at other venues, as well as recently published results. In addition, we have the following policies.

• [Submission on previous conference and workshop papers] We request significant updates if the work has previously been presented at major machine learning conferences or workshops before, or has been presented at any conferences or workshops before February 1st 2025.
• [Submission on previous journal papers] For published work in journals that have not been presented in conferences or workshops, we will let the authors decide how novel it is for the community. Though the machine learning community moves fast, the workshop is inclusive for subareas that may have taken a slower pace, and values submission stands for fundamental long-lasting research.
• [Dual submission to other workshops at the same time, e.g., another ICLR workshop] We generally discourage dual submission to other workshops at the same time as it would be a waste of our program committees' efforts, and we request an in-person presentation by either talk or poster upon acceptance at our workshop. That being said, as our workshop is non-archival, we leave the final decision to the authors for dual submission.

Tiny Papers Submissions

[Remark] This year, ICLR is discontinuing 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 more details. 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 2025 will become available on ​https://iclr.cc/Conferences/2025/ at the beginning of February and close on March 2nd.

We encourage submission of short papers relevant to the workshop topics. Following Tiny Papers Track in previous years' ICLR main conference, we encourage submissions from historically underrepresented group, and example topics such as

• An implementation and experimentation of a novel (not published elsewhere) yet simple idea, or a modest and self-contained theoretical result
• A follow-up experiment to or re-analysis of a previously published paper
• A new perspective on a previously published paper

The tiny papers will be peer reviewed. Submissions should be double-blind, no more than 3 pages long (excluding references), and following the ICLR'25 template. Use the same sumbission portal in OpenReview. In addition,

• Please clearly add a tag [Tiny] at the beginning of the submission title.

Camera Ready Instructions

Please keep using the ICLR template for camera ready, and feel free to update the footnote/header in the template from ICLR main conference to workshop.

We allow an extra page (i.e., max 7 pages for regular paper and max 4 pages for tiny papers) for the camera ready to properly address reviewers' comments, add authors and acknoweledgement information. The accepted paper pdf files will be released on openreview after the camera ready deadline.

Presentation Instructions

All accepted papers are expected to be presented in person. While we aim to provide accessibility to virtual attendees of the workshop, we are not planning to provide support for virtual talks or posters.

All accepted papers are expected to have in-person posters, which should be portrait orientation up to A1 size 23.4"w x 33.1"h (W 59.4 x H 89.1 cm) size.

Each spotlight presentation including QA is 10 min.

See ICLR poster instructions for onsite poster print services.
