This document compares various machine learning algorithms to accurately predict fetal risk levels based on performance metrics. It discusses collecting and preprocessing data from an online repository to build models using Random Forest, Bagging, AdaBoostM1, SMO, Kstar, Naive Bayes, Hoeffding Tree, and Classification via Regression algorithms. These algorithms are evaluated based on precision, recall, F-score, and training time. Random Forest is found to have the highest accuracy of 99.9% and is the preferred algorithm for fetal risk prediction based on its performance metrics.
