Researchers have developed a novel framework called Hyperbolic Learning on Brain Graphs (HLBG) to analyze functional brain networks and diagnose disorders. This approach leverages deep hyperbolic learning to model the inherent hierarchical structure of brain networks, from individual ROIs to whole-brain integration. HLBG projects representations into Lorentzian hyperbolic space and incorporates a Graph-aware Mamba (GaMamba) model to capture long-range dependencies while preserving topological information. Experiments on the ABIDE-I and REST-MDD datasets show that HLBG surpasses existing state-of-the-art methods and identifies biomarkers relevant to disorders. AI
