Gradient-Based Explainable Graph Attention Networks for Parkinson’s Disease Classification Using Feature-Informed Structural Brain Networks
Parkinson’s disease (PD) is a progressive neurodegenerative disorder caused by degeneration of dopaminergic neurons in the substantia nigra, leading to motor and non-motor impairments. Early diagnosis is important because timely intervention may improve symptom management and slow disease progression. However, subtle s...
