MovieSTAGE: Scene, Transition, and Global Encoding for Movie-fMRI ADHD Classification
MovieSTAGE: פרקטיקה חדשה לזיהוי ADHD בעזרת fMRI של סרטים, המשלבת קודים, תרגילים ואפילוגה גלובלית.
תקציר מקורי באנגליתarXiv:2610.09306v1 Announce Type: new Abstract: Naturalistic movie-fMRI provides a shared, temporally structured probe of brain dynamics, yet predictive models commonly rely on whole-run functional connectivity (FC) or temporally generic representations that are not aligned with narrative events. We introduce MovieSTAGE (Scene, Transition, and Global Encoding), a multiscale framework that combines hypergraph-structured FC-profile organization within scenes, unsigned FC-profile differences across adjacent scenes, and whole-movie FC. We evaluated 260 participants from the CMI-HBN Despicable Me cohort on case-control, ADHD-subtype, and three-class classification using 10 repetitions of stratified five-fold cross-validation, complete out-of-fold (OOF) predictions, and paired subject-cluster bo
