Overview
5.8 million Americans live with Alzheimer’s dementia, including 10% of all seniors 65 and older. Scientists at Cornell have discovered links between “stalls,” or clogged blood vessels in the brain, and Alzheimer’s. Stalls can reduce overall blood flow in the brain by 30%. The ability to prevent or remove stalls may transform how Alzheimer’s disease is treated.
Stall Catchers is a citizen science project that crowdsources the analysis of Alzheimer’s disease research data provided by Cornell University’s Department of Biomedical Engineering. It resolves a pressing analytic bottleneck: for each hour of data collection it would take an entire week to analyze the results in the lab, which means an entire experimental dataset would take 6-12 months to analyze. Today, the Stall Catchers players are collectively analyzing data 5x faster than the lab while exceeding data quality requirements.
The research team has realized there are aspects of this task that are best suited to uniquely human cognitive faculties as explained in this blog post. However, some portion of the data, the “low-hanging fruit,” may be within reach of machine learning models that are able to distinguish between easy and difficult data and are applied only in cases where they have been validated to meet the researchers’ data quality requirements. If a machine learning classifier could be used for 50% of the data, it would double the analytic throughput of Stall Catchers and could achieve the original goal of analyzing the data 10x faster than the lab. This could ultimately put finding an Alzheimer’s treatment target in reach within the next year or two.
Through the Stall Catchers project, there is now a one-of-a-kind dataset that can be used to train and evaluate ML models on this task. Each exemplar is an image stack (a 3D image) taken from a live mouse brain showing blood vessels and blood flow. Each stack has an outline drawn around a target vessel segment and has been converted to an mp4 video file. The objective of this competition is to classify the outlined vessel segment as flowing—if blood is moving through the vessel—or stalled if the vessel has no blood flow.

Selection of winners
This Competition is a challenge of skill and the final results are determined by evaluating a combination of quantitative and qualitative factors, as more fully described on the Competition Website. For that portion of the Competition evaluated quantitatively, the results will be determined solely by leaderboard ranking on the private leaderboard based on an objective statistical evaluation metric published on the Competition Website prior to commencement of the Competition (subject to compliance with these Competition Rules). Participants' scores and ranks on the Competition Website at any given stage of the Competition will be based on the objective statistical evaluation metric described on the Competition Website, as determined by applying the predictions in the Submission to the ground truth of a validation dataset whose instances were a fixed set sampled from the Data. For that portion of the Competition evaluated qualitatively, the results will be determined by a panel of judges, as more fully described on the Competition Website. As more fully described on the Competition Website, the Competition may have a quantitative winner, a qualitative winner, a combined quantitative and qualitative winner, or all three.
The evaluation metric used for scoring and ranking Submissions will be displayed on the Competition Website.
Any prize awards are subject to verification of eligibility and compliance with these Competition Rules. All decisions of DrivenData, the Competition Sponsor and/or judges will be final and binding on all matters relating to this Competition. DrivenData reserves the right to examine the Submission and any associated code or documentation for compliance with these Competition Rules. In the event that the Submission demonstrates a breach of these Competition Rules, Competition Sponsor or DrivenData may at its discretion take either of the following actions:
- disqualify your Submission(s); or
- require that you remediate within one week all issues identified in your Submission(s) (including, without limitation, the resolution of license conflicts, the fulfillment of all obligations required by software licenses, and the removal of any software that violates the software restrictions).
A tie between two or more valid and identically ranked submissions will be resolved in favor of the tied submission that was submitted first.
A Participant may decline to be nominated as a Winner by notifying DrivenData directly within one week following the Competition deadline, in which case the declining Participant forgoes any prize or other features associated with winning the Competition. DrivenData reserves the right to disqualify a Participant who so declines at DrivenData's sole discretion if DrivenData deems disqualification appropriate.
