This document discusses predicting the risk of heart disease using machine learning techniques. The authors aim to build a model that can predict the probability of a patient having heart disease by processing patient datasets. They test several classification and regression algorithms on a heart disease dataset from Kaggle and find that decision tree algorithms provide the most accurate results for classification, achieving 99.5% accuracy. For regression, random forest regression achieves the highest accuracy at 84.68%. The authors conclude machine learning can effectively analyze medical data and identify risk factors for diseases like heart disease.
