In September 2023, NIDDK-CR announced the Data Centric Challenge aimed at enhancing NIDDK datasets for future AI applications. Challenge participants were tasked with generating an AI-ready dataset that could be used for future data challenges and producing methods to enhance the AI-readiness of NIDDK data. Participation in the Challenge was tiered (i.e., beginner-level and intermediate/advanced-level) and utilized data from two longitudinal studies focused on type 1 diabetes (TEDDY and TrialNet).
