Adaptive filtering enhances Alzheimer's disease classification using multimodal brain data, suggesting improved diagnosis capabilities.

To develop a model for early detection of Alzheimer's Disease by leveraging spectral-domain information from brain networks.
Construction of structural and functional brain network graphs using DTI and rs-fMRI data.
Implementation of a frequency-encoding-guided attention mechanism for spectral filter adaptation.

Achieved accuracies of 96.64% for AD vs. NC and 90.48% for MCI vs. NC classifications.
Attained an accuracy of 87.12% in distinguishing among three disease stages.
Demonstrated significant improvement over baseline methods in classification tasks.
