This document presents a comparative study of machine learning models for detecting Alzheimer's disease. The study uses MRI data to extract features like brain volume and uses those as inputs to various machine learning models like logistic regression, support vector machines, decision trees, random forests and AdaBoost. The performance of each model is evaluated using metrics like accuracy, sensitivity and specificity. The results show that the random forest model performs the best with the highest prediction rates, indicating it has potential for accurate early detection of Alzheimer's using MRI data.
