Classification of Smoking Cessation Status: Applying Machine Learning Methods to Health Survey Data




This study examined the ability of a backpropagation neural network classifier to distinguish between current and former smokers in the 2000 National Health Interview Survey sample adult file. A multilayer artificial neural network was contructed to predict class membership, current or former smoker, using the attribute subset. Classifier performance exceeded that of random chance. However, separation of current and former smokers was imperfect. Additionally, performance did not exceed that of a comparison classifier created using logistic regression. Imprecise, but high quality health survey data provided sufficient information for prediction of smoking cessation status. Membership of specific survey items in the attribute subset was large
