Fyi, very relevant to all of us who work on algorithms for time series
analysis, especially foundation models

*Announcing the PhysioNet Challenge 2025*



Dear Community,



We are excited to announce the opening of the George B. Moody PhysioNet
Challenge 2025 <https://physionetchallenges.org/2025/>. *The 2025 Challenge
invites teams to develop algorithms for using electrocardiograms (ECGs) to
identify cases of Chagas disease.*



Chagas disease is a parasitic disease that is primarily transmitted by
triatomine insect bites. It affects an estimated 6.5 million people and
causes nearly 10,000 deaths annually, primarily in Central and South
America. Serological testing can detect Chagas disease and allow for
treatment to slow or prevent damage to the cardiovascular system, but
testing capacity is limited. Chagas disease symptoms may also appear in
ECGs, so automated approaches can help to prioritize individuals for the
limited numbers of serological tests and inform the impacts of and
treatments for Chagas disease.



We have shared training data from the CODE-15% dataset
<https://zenodo.org/records/4916206>, and we will introduce more training
data during the unofficial phase. We have shared example entries and
scoring code in both MATLAB and Python, and we will share more complex
examples during the unofficial phase. We will open the scoring system in
the coming days.



See the Challenge website for more information, rules and deadlines:
https://physionetchallenges.org/2025/.



As in previous years, we have divided the Challenge into two phases: an
unofficial phase and an official phase. The unofficial phase solicits
feedback from the research community (i.e., you) to help us improve the
Challenge for the official phase, *so we require teams to register
and participate in the unofficial phase of the Challenge for prize
eligibility*. Please enter early and often – we need you to look for quirks
in our data, our scoring system, and otherwise. We are imperfect (and
bandwidth-limited), so please send us suggestions via the forum (see
below). *We rely on the community to help us to improve the quality of the
Challenge each year.*



The culmination of the Challenge will be in Brazil at the annual
meeting of Computing
in Cardiology <http://cinc2025.org/>, where we will present prizes at the
closing ceremony. We're excited to announce that we are *once again
providing an additional prize for teams from the Global South to encourage
representation from underrepresented groups*.



We will post more information on the PhysioNet Challenge website
<http://physionetchallenges.org/2025/> and the Challenge forum
<https://groups.google.com/g/physionet-challenges/> as it becomes
available, or when your input helps us modify the boundaries and content.
Please post questions and comments to the Challenge forum as well. However,
if your question reveals information about your entry, then please email *info
[at] **physionetchallenge.org* <http://physionetchallenge.org/> instead to
help us safeguard the diversity of approaches to the Challenge. We may
share parts of our replies publicly if we feel that all Challengers should
benefit from the information contained in our responses. We will not answer
emails about the Challenge sent to other email addresses.



We thank you for your continued interest and support, and we hope that you
enjoy the 2025 Challenge!



Best of luck!
