Model Structure of Fetal Health Status Prediction

Abstract

One of the issues of pregnant mothers in Indonesia is their access speed and accuracy services availability towards the prediction of fetus or baby conceived during pregnancy. Thus, the research aimed to obtain the ability to predict three ranges of a fetal target, namely normal, risk, and abnormal condition. This research emphasized the modeling aspect of supervised learning using seven different algorithms to obtain an optimal working score. Those are Decision Tree, Gradient Boosting, Random Forest, SVM, k-NN, AdaBoost, and Stochastic Gradient Descent (SGD). The structure process is mainly divided into two steps, pre-process model and the prediction model. An early data pre-process is needed before executing. Prediction output indicated that dataset test is valid, and can be proven by comparing between the testing data table and prediction and testing table diagram. The resulting model has described the sequence for simulating the training and testing data model to produce the highest working score from the seven selected algorithms. The simulated data based on the model created is proved its validity thru three main filter processes, which are missing data solution, outlier data control, and data normalization. The result obtained a working score that has data proximity with a low score range of 0.063 from model evaluation, confusion matrix, and prediction output.

Examining the Joint Effects of Air Quality, Socioeconomic Factors on Indonesian Health

“…Advancements in scientific understanding over the past decades have illuminated the profound impact of indoor air quality on human health [3]. Research efforts have been devoted to identifying sources, exposures, and health outcomes related to indoor air pollution, encompassing pollutants like ozone, formaldehyde, radon, cigarette smoke, volatile organic compounds (VOCs), pesticides, and semi-volatile organic compounds (SVOCs).…”
