An expert routing-driven graph framework from tongue multi-task features to liver fibrosis prediction

Liver fibrosis is a global health concern where early detection is crucial for timely intervention. Traditional Chinese Medicine tongue diagnosis offers a promising non-invasive assessment, but suffers from inter-observer variability and subjective interpretation. Current artific...

Supersolvable closures of finitely generated subgroups of the free group
