PhysioNet Challenge
Overview
The annual George B. Moody PhysioNet Challenges invite participants to develop algorithmic approaches tackling clinically interesting questions that remain unsolved. Since the launch of PhysioNet in 1999, PhysioNet has co-hosted these Challenges in collaboration with Computing in Cardiology.
2026 George B. Moody PhysioNet Challenge
The George B. Moody PhysioNet Challenge 2026 invites teams to develop algorithms for using polysomnograms (PSGs) to predict cognitive impairment from sleep studies.
The George B. Moody PhysioNet Challenge 2026 asks participants to develop and implement open-source algorithms for using PSGs to predict future diagnoses of cognitive impairment. The winners of the Challenge will be the team with the highest score on the hidden test set.
2026 Challenge
“Screening for Cognitive Impairment During Sleep Studies”
Data
The 2026 Challenge data are from the Human Sleep Project database and include clinical PSG data from five different U.S. institutions: Beth Israel Deaconess Medical Center (BIDMC), Emory University, Kaiser Permanente, Massachusetts General Brigham (MGB), and Stanford University. Each study includes synchronized physiological signals and human and automated annotations of sleep stages, arousals, and respiratory and limb movement events.
