Topology, Algebra, and Geometry in Data Science (TAG-DS) 2026

Submission information

TAG-DS is offering 3 submission tracks this year:

Full archival paper track (8-pages excluding references, appendices, and supplementary material)

• Full archival papers must include novel work, results, and theory consistent with requirements for publication as completed research with clear conclusions. Submissions must stand-alone, independent of appendices and supplementary material.

• Accepted full archival papers will be published in the associated PMLR volume

Non-archival extended abstract track (4-pages excluding references)

• Non-archival extended abstracts may include work in progress or summaries of work that has been or will be published in alternative venues

• Will not be published in the associated PMLR volume

Open-problem/conjecture track (3-pages excluding references)

• Open-problem/conjecture submissions should describe important open problems within the TAG space

• What are the major questions at the interface of AI and math? We are specifically looking for questions that are broad enough to be accessible and of interest to a significant fraction of attendees but remain focused on TAG topics. Examples might include: a better understanding of how specific mathematical perspectives might apply to machine learning; a theoretical explanation of observed phenomena (e.g., “why do equivariant architectures always…”); or methods of measuring TAG-relevant quantities “how can we measure X in large foundation models?” This track is also appropriate for posing open conjectures to engage the community and seed future collaborations.

• Will not be published in the associated PMLR volume

**** Only accepted, full archival-track papers will be published in the associated PMLR volume ****

Submission topics (non-exhaustive list)

• Mathematically-constrained representation learning

• Symmetry in data and learning

• Novel architectures

• Alternative learning objectives

• Training schemes

• Robustness

• AI for Math

• Model Evaluation

• Datasets, Explainability

• Reduced-order and Energy Efficient Models

• Domain-driven Data Analytics

• Survey papers relevant to the TAG-DS community

Submission website

The OpenReview submission website is the same for all three tracks:

Templates

To travel from Boston to Northeastern University using public transportation (MBTA):

Subway (T)

• Take the Green Line E branch (also known as the “E Line”) outbound towards Heath Street.

• Exit the train at the “Northeastern University” station.

• Northeastern University is within walking distance from the station.

Commuter Rail

• If you are coming from a location outside of Boston and closer to a Commuter Rail station, you can take a Commuter Rail train that services the Ruggles station. 

• From Ruggles station, it's just a short walk to Northeastern University.

Bus

• Various MBTA buses service the Northeastern University area. 

• You can check the MBTA website or use the Transit app for specific bus routes and schedules, as they may change from time to time.

For the most up to date information on public transportation, please refer to the official Massachusetts Bay Transportation Authority (MBTA) website or Transit app.

Parking

Where can I find up-to-date news about the conference or changes to the schedule?

• We will strive to keep this website up-to-date through the end of the conference, but the for real-time conference updates and news please follow the TAG-DS twitter account (@TAGinDS) for real-time conference updates and news. If you do not have a Twitter account and are having trouble viewing the feed, tools like Twitter Web Viewer will enable you to see our posts without logging in.

How do I submit a paper to the Boston TAG Party?

• The OpenReview submission website can be found here: https://openreview.net/group?id=TAG-DS/2026/Conference. More details are available in the 'Tools for Authors' section above.

Does my paper submission have to follow particular formatting requirements?

• Yes, all submissions must use the provided LaTeX template for paper submissions.  The template provides three formatting options, for the initial submissions, manuscripts from all three tracks should use the submission  option (this is already set as the default) which anonymizes the authors to facilitate the reveiw process. If your manuscript is accepted, you will submitted a camera-ready version using either the proceedings option, for accepted full archival (proceedings) papers or the nonproceedings option for accepted non-archival extended abstracts and accepted open-problem/conjecture track papers. If you have questions, please email us at: info@tagds.com. More specific details on the formatting requirements are available within the template.

What is the deadline for paper submission?

• The Boston TAG Party is offering three submission tracks, a full archival paper track, a non-archival extended abstract track, and a open-problem/conjecture track.  The deadline for all three tracks is the same: June 15, 2026 - Anywhere On Earth (AOE).  A countdown to the deadline is available in the 'Important Dates' section above.

What is the difference between the three submission tracks? Which track is right for my manuscript?

• The a full archival paper track must include novel work, results, and theory consistent with requirements for publication as completed research with clear conclusions. If you want your paper to be considered for publication in the conference proceedings, this is the track to which you should submit. Submissions should be no more than 8 pages long, not including references, appendices, or supplementary materials, and should be self-contained, independent of appendices or supplementary material.

• The non-archival extended abstract track is less formal.  Submissions to this track might include work in progress or summaries of work that has been or will be published in alternative venues. Manuscripts submitted to the non-archival extended abstract track will not be published in the conference proceedings, but will still be presented at the conference if accepted. Submissions should be no more than 4 pages long, not including references.

• The open-problem/conjecture track is intended as a way for our community to define some of future directions of TAG research.  Submissions should describe important open problems within the TAG space that are broad enough to be accessible and of interest to a significant fraction of the Boston TAG Party attendees but remain focused on TAG topics. Submissions to the open problems/conjectures track will not be considered for publication in the conference proceedings, however we are working to create a public repository for these ideas for ongoing community engagement. More details will be available closer to the start of the conference. Submissions should be no more than 3 pages long, not including references.

• If you are having trouble deciding which track is right for you, feel free to email us at: info@tagds.com. We would be happy to help.
