We are excited to announce the opening of the George B. Moody PhysioNet Challenge 2025. This year, the challenge focuses on developing algorithms to identify Chagas disease using electrocardiograms (ECGs).

Chagas disease affects over 6.5 million people worldwide, with a significantly higher prevalence in the Global South. It is often detected through serological testing, which is limited in availability. Using ECGs for automated detection can help prioritize testing and improve treatment efforts.

Participants will work with initial training data from the CODE-15% dataset, with additional data to be shared as the challenge progresses. Example entries and scoring code are available in both MATLAB and Python to help teams get started. As usual, the challenge is divided into two stages: an unofficial phase for community feedback and an official phase. This year's challenge will conclude in Brazil at the annual Computing in Cardiology conference, where winners will be announced. Additional prizes are available to encourage participation from teams in the Global South.

@zhang_yueting @gabrielpeyre Indeed, a linear systems equivalent to the central limit theorem is that the cascade of many linear systems bahaves like a single Gaussian-shaped impulse response, which is also Gaussian in the frequency domain :)

[Reza Sameni @RezaSameni]

@StephaneDeny @MBCarr0 @gabrielpeyre Yes - we just need robust measures for gaussianity, which is basically what the different flavors of classical ICA algorithms boil down to. Of course, there's a different approach based on the joint approximate diagonalization of eigenmatrices, like JADE and SOBI. Fun stuff!

@martinmbauer Very interesting. What's the interpretation of this curve? Since R, volume and surface areas have dimensions, each point of the curve has a different dimension and we can't compare them without unit normalization. Or maybe I'm missing something.
