Rules
Account and Team
- Each participant can join at most one team.
- Normally, each participant/team can only submit one algorithm to each track.
- If you or your team have sufficiently distinct algorithms, you may submit more than one algorithm to a modality track, subject to approval from us.
- Please reach out to us if want to split into sub-teams or submit multiple algorithms.
- We will exclude duplicate submissions from final leaderboards.
- We will exclude anonymous submissions unless we can verify your profile.
Inference Environment Restrictions
The inference runtime environment on Grand-challenge cloud platform has the folowing setup:
- 1x NVIDIA T4 GPU with 16 GiB VRAM
- Main memory of at most 32 GiB DRAM ⚠️
- Maximum 15 minutes per image for now (can be extended to 20 minutes if this is a bottleneck for most participants)
- More info on the cloud platform can be found here.
Please take note of the above inference restrictions when designing your algorithm.
Usage of Training Data
Participants may use any other public datasets and private in-house data, or modify the supplied TopBrain 2025 training data, provided that they disclose and mention any additional or modified training datasets in their description of the submitted algorithm (please see "Publication policy" below).
Members of the Organizing Institutes
Members of the organizers' direct research groups can participate and their results can be included in the publications and the leaderboard. However, they are not eligible for awards. This policy also applies to teams that include such members.
Award and Result Announcement Policy
Top 3 teams (excluding the organizer teams) from each of the two tracks will be publicly named and given a certificate along with a booklet "Anatomy of the Brain Illustrated Pocket Anatomy" 🧠 as a souvenir at the in-person challenge event.
All participants/teams are invited to prepare a 4-minute presentation/video for the challenge session to present and discuss their methods. If you are joining the event, please fill up the contact form soon. See below.
After the public announcement, a detailed analysis of the submitted results will be available upon request.
🏆 📰 Publication Policy
The challenge results will be summarized and published in a journal manuscript. All participants with a (reasonable) submission are invited to contribute to our challenge publication!
In order for us to include you in our paper, please:
- Fill up a contact form to help us verify your authorship.
-
Fill up a short questionnaire regarding your algorithm submission
- We will ask you a few things about your algorithm such as the method description, data used, data preprocessing, data augmentation, training strategies, amount of compute and the type of resources used.
- Questionnaire will be emailed directly to participants who have given us their contacts.
The above are the minimal requirements. You are of course welcome to send us more paragraphs + figures about your submission.
NOTE: this is required for the co-authorship even if you are awarded and announced for winner or have presented in the event. (for the academic value of the summary paper)
Each submission can have maximum three co-authorships for the challenge paper. Additional authors from the top submissions can be included upon request with justification according to the ICMJE authorship guidelines.
Participating teams may submit their results separately without any publication embargo.
