One major challenge in Type 2 Diabetes (T2D) is the enormous heterogeneity associated with the disease. This pilot funding program, through the NIDDK Information Network (dkNET, https://dknet.org), is designed to capitalize on the rapid advances in AI and other data science areas in addressing major gaps in the study of Type 2 Diabetes (T2D) heterogeneity, including opportunities in extracting knowledge from the enormous amount of data and literature, and in recruiting AI experts to this area of domain science. It calls for multi-disciplinary teams to: 1) develop AI foundation models for T2D; (2) validate the models with top research questions in T2D heterogeneity; (3) disseminate the models and engage the community for further development, validation and application; and (4) develop use cases that demonstrate the models’ potential in accelerating research in diabetes heterogeneity study. The teams are expected to work with dkNET to coordinate their projects, so that awardees can integrate and share products through the dkNET platform.
