1. Challenge Description
The MABe Challenge is a competition to facilitate the progress of multi-agent behavior modeling. Whereas the 2021 MABe Challenge focused on accurately detecting human-defined behaviors of interest from animal tracking data, our goal for 2022 is to highlight unsupervised approaches to behavior analysis. Numerous groups have proposed unsupervised methods to identify types of animal behavior in a data-driven manner. However, due to a lack of benchmark datasets or metrics in behavioral neuroscience, each lab typically develops and evaluates methods on their own in-house data; there is no consensus in the field as to what constitutes a “good” unsupervised representation of animal pose and movement. The goal of this year’s challenge is for participants to develop and test unsupervised behavioral embeddings set of benchmark datasets for the evaluation of unsupervised behavior representations. For this year’s challenge, we release a new trio of datasets from behavioral neuroscience, including social interactions in mice, flies, and ant-beetle pairs. Teams will be tasked with creating low-dimensional representations, or “embeddings”, that characterize animals’ actions in these three datasets, given either keypoint-based estimates of animals’ poses or raw videos of their interactions. We will evaluate the quality of these representations on a set of experimentally relevant benchmark tasks, such as detecting social behaviors, identifying differences between animal strains, or distinguishing effects of optogenetic stimulation. To prevent teams from fine-tuning their embedding to the evaluation tasks, only a small number (~2) of tasks will be known to the teams- all other tasks will be hidden for the duration of the challenge.
Your contribution will help improve our depth of understanding of animal behaviors in real datasets from neuroscience; these improvements can help accelerate behavioral experiments, and help us better understand the relationship between brains and behavior. Eligible winners of the challenge will be invited to speak at our Multi-Agent Behavior Workshop at CVPR2022; participation in the workshop is not required to win.
This Challenge will be run in accordance with these Official Rules (“Rules”).
The Challenge is organized and sponsored by Northwestern University, and Janelia, with additional prize sponsorship by Google and Amazon (additional sponsors pending.) Northwestern, and Janelia collectively are referred to as the “Organizers.”

9. How will Winners be Selected and Notified?
Entries will be judged via an algorithm that will generate a score based upon which Entries will be ranked. The rankings will be displayed on the AIcrowd Site’s Challenge specific leaderboard (“Leaderboard”).
In each task the algorithm will rank your Entry as follows:
The Challenge Organizers have constructed a hidden set of labels for a variety of subtasks (such as detecting occurrence of behaviors or determining the strain of the animal.) Following Entry submission, an automated script will split the Entry into training and test sets using 3 random seeds, and pair these sets with their associated hidden labels. The script will then train a single-layer neural network for each behavioral subtask in a supervised fashion, and evaluate network performance on the held-out test set to produce either an F1 score (for binary labels) or a mean squared error (MSE, for continuously valued labels) for each subtask.
To translate F1 and MSE scores to leaderboard ranking, we will use the following system. For each subtask, all Entries will be ranked according to their F1 (higher is better) or MSE (lower is better) scores. We will then average rankings across subtasks, to determine an overall Average Rank. The overall leaderboard ranking will then be determined by this Average Rank. There will be a separate leaderboard for each of the four tasks.
If two or more participating Teams have the same score, the higher ranking will be awarded to the team having the greatest number of first-place rankings across subtasks. If teams are still tied, the higher ranking will be awarded to the team with the highest mean F1 score (averaged with (1 – mean MSE), for the mouse task.)
If scores and error are identical, prizes will be shared evenly among the Teams.
Potential winners will be contacted within one week of each Deadline via the email address associated with the AIcrowd.com account through which the Entry was submitted. If a potential winner cannot be contacted, does not respond as directed, refuses the prize, or is found to be ineligible for any reason, such prize may be forfeited and awarded to an alternate winner. Only one alternate winner will be selected per each prize package, after which prizes will remain unawarded.
To the extent that there is any dispute as to the identity of the potential winner, the official account holder of the email address associated with the AIcrowd account through which the Entry was first submitted will be deemed the official potential winner by Organizers.
10. Your Odds of Winning
THE ODDS OF WINNING A PRIZE ARE SUBJECT TO THE TOTAL NUMBER OF ELIGIBLE ENTRIES RECEIVED, AND HOW YOUR ENTRY SCORES IN ACCORDANCE TO THE JUDGING CRITERIA. The total number of participants in the previous year of this challenge was 271.
The prize pool is approximately $12000 USD in total. It will be assigned as follows:
There will be four tasks and a leaderboard for each task. The top team in each leaderboard is assigned $1500, the second place team in each leaderboard is assigned $1000, and the third place team in each leaderboard is assigned $500. The winning individuals may incur tax liability.
12. When will prizes be awarded?
The prizes will be awarded within a commercially reasonable time frame. All members of a Team may be required to complete and sign additional documentation, such as non-disclosures, representations and warranties, liability, consent for use of the members’ names and publicity releases (unless prohibited by applicable law), and tax documents, or other similar documentation in order for the potentially winning team to claim the prize. If each Team member does not agree to complete and sign the additional documentation within a reasonable time, the Organizers may choose another Entry by another Team. Organizers will in no way be involved in any dispute with respect to receipt of a prize by any other members of a Team.
