About the project
This challenge began in 2019 when the French Society of Pathology (SFP) and the Health Data Hub (HDH) decided to build a challenge using a data bank of whole slide images (WSIs). Nineteen public and private pathology departments across France contributed more than 5,000 WSIs as data for the challenge. These slides are often difficult for pathologists themselves to diagnose, and expert eyes may be required. All labeled images included in the challenge were reviewed twice by expert pathologists.
The results from the challenge will be announced at the Carrefour Pathologie national congress at the beginning of November 2020. The challenge organizers plan to make the dataset of WSIs available online after the event to allow for further learning and algorithmic improvements.
About the organizers
The French Society of Pathology (SFP) promotes research and teaching in Pathology in France and organizes the annual Carrefour Pathologie meeting in Paris.
A key component of French President Macron’s AI strategy, the Health Data Hub (HDH) is a public one-stop health data access point and technological platform for public interest research conducted by academic and industrial research teams. Officially created in December 2019, the HDH seeks to provide simple, unified, transparent and secure access to health data in compliance with regulations and citizens' rights. The HDH provides infrastructure, a database catalogue and related services. These services include providing access to health data, supporting data collection, and facilitating data consolidation and use.
The primary sponsor of the challenge is Grand Défi: Artificial Intelligence for Diagnosis, a program launched by the French Innovation Council.

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 any issues identified in your Submission(s) (including, without limitation, the resolution of license conflicts and confirmation of the fulfillment of all obligations required by software licenses).
