Semantic locality-aware biclustering for brain functional network connectivity
BrainBiC is a novel deep biclustering framework that enhances the analysis of brain functional connectivity, particularly in schizophrenia. It addresses the challenges of subject heterogeneity by jointly stratifying subjects and features, enabling the discovery of meaningful connectivity patterns. The framework demonstrates superior performance in identifying distinct brain connectivity subgraphs that correlate with cognitive functions and clinical symptoms, thus advancing precision psychiatry. Extensive experiments across multiple neuroimaging datasets validate its effectiveness in capturing the complexities of brain dynamics.
