Abstract

WombCare AI focuses on improving maternal and fetal healthcare through a structured data-driven approach that supports clinical decision-making and early risk identification. The system integrates maternal clinical parameters and CTG signal data to provide a unified understanding of fetal condition and birth outcomes. Traditional monitoring approaches often remain subjective and inconsistent, which creates variability in diagnosis and delays in intervention. The framework of WombCare AI is conceptualized as a machine learning-driven construct that enables predictive analysis and classification by operationalizing clinical data patterns across layered computational processes, thereby facilitating accurate fetal assessment and birth weight estimation while contributing to improved obstetric care outcomes. The system performs two primary tasks, including birth weight prediction and fetal health classification. Regression models such as Random Forest and AdaBoost are utilized to estimate birth weight based on maternal attributes like age, weight, gestation, and lifestyle factors. Classification models, including Logistic Regression and an ensemble of support vector classifiers, Random Forest, decision tree, and AdaBoost, are applied to CTG data to categorize fetal health into Normal, Suspect, and Pathological conditions. The proposed multi-model framework achieves a macro recall of 0.921941, significantly outperforming the Logistic Regression baseline (0.757944), and achieves a test set RMSE of 0.441 in birth weight prediction, demonstrating superior generalization. This dual pipeline approach enables early detection of complications such as fetal distress and low birth weight risk, thereby enhancing diagnostic precision and supporting timely obstetric intervention.
