Early diagnosis of Alzheimer's Disease (AD) remains a critical challenge in medical imaging and artificial intelligence. Machine learning techniques applied to neuroimaging datasets have shown promising results in assisting clinicians with early detection of AD. This paper presents a robust feature extraction approach based on Noisy Deep Dictionary Learning (NDDL). The proposed framework integrates hierarchical sparse representation with noise-based regularization to improve robustness and generalization of learned features. Experiments conducted using MRI scans from the Alzheimer's Disease Neuroimaging Initiative (ADNI) dataset demonstrate improved classification performance compared with traditional machine learning and deep learning models. Results indicate that the proposed approach achieves higher accuracy while maintaining interpretability of learned representations.
