Early diagnosis and appropriate assessment of disease progression are critical for treatment and improving patient’s health. Currently, the diagnosis of these neurodegenerative diseases is based primarily on mental status exams and neuroimaging scans, which are costly, time-consuming, and sometimes erroneous. A novel, cost-effective, and precise diagnostic tools and techniques are thus urgently required, particularly for early detection and prediction. In the recent decade, electromagnetic imaging has evolved as a cost-effective and non-invasive alternative approach for studying brain diseases. These studies focus on wearable and portable devices and imaging algorithms. However, microwave imaging can not detect minimal changes in the brain at early stages accurately due to its lower resolution. This paper investigates machine learning techniques for the early diagnosis of acute neurological diseases, especially Alzheimer’s disease. A machine-learning-based classification method is proposed. Simulations are performed on realistic numerical brain phantoms using the CST studio suite to get the scattered signals. A novel data augmentation method is proposed to generate synthetic data required for machine learning algorithms. A deep neural network-based autoencoder extract features to train various machine learning algorithms. The classification results are compared with raw data and manual feature extraction. The study shows that the proposed machine learning-based method could be used to monitor Alzheimer’s disease at its early stages.  \nIndex Terms—Alzheimer’s disease (AD), classification, data augmentation, microwave sensing, machine learning, radar data.  \nI.
