GraD-IBD: Graph Representation Learning from Diagnosis Trajectories for Early Detection of Inflammatory Bowel Disease
Researchers propose GraD-IBD, a graph-based machine learning model that analyzes patient diagnosis histories encoded in ICD codes to detect inflammatory bowel disease risk earlier and more efficiently than existing sequential models. The approach reformulates longitudinal diagnostic trajectories as temporally directed graphs with a novel message-passing mechanism, demonstrating improved accuracy while reducing computational complexity.
