Abstract

Objective: To introduce an original case-based machine learning (ML) and prediction system Constud and its application on tabular data for estimation of the risk of enterobiasis among nursery school children in Estonia. Methods and materials: The system consists of a software application and a knowledge base of observation data, parameters, and results. The data were obtained from anal swabs for the diagnosis of enterobiasis, from questionnaires for children's parents, observations in nursery schools and interviews with supervisors of the groups. The total number of studied children was 1905. Ten parallel ML processes were conducted to find the best set of weights for features and cases. Results: The best goodness-of-fit according to the true skill statistic (TSS) was 0.381. Approximately equal fit can be reached using different sets of features. Cross-validation TSS of logit-regression and classification tree models was
