Interpretable Alzheimer's Diagnosis via Multimodal Fusion of Regional Brain Experts
Researchers have developed a new model called MREF-AD, a Mixture-of-Experts framework designed for the multimodal diagnosis of Alzheimer's disease. This model integrates regional brain experts from different neuroimaging modalities like amyloid PET and MRI, using a gating network to adaptively balance their contributions. MREF-AD not only achieves competitive performance compared to existing methods but also provides interpretable insights into how structural and molecular imaging data jointly inform Alzheimer's diagnosis.
