Machine Learning Algorithms.The global rise in cesarean deliveries often performed out of precaution rather than medical necessity highlights the need for objective decision-making tools in obstetrics. This study explores the application of machine learning algorithms to predict the mode of childbirth, distinguishing between vaginal normal and cesarean deliveries. By analyzing maternal and fetal health data, this project evaluates the effectiveness of multiple algorithms and feature selection methods to identify the most critical clinical parameters influencing delivery outcomes. The ultimate aim is to assist healthcare professionals in making evidence-based decisions that improve maternal and neonatal care.
Objectives
Predict the mode of childbirth using of clinical and maternal health data.
Compare the performance of various machine learning algorithms.
Identify key predictive features related to the maternal and fetal health.
Provide data driven decision support for the obstetric care planning.
Problem Statement
Obstetricians frequently rely on subjective clinical judgment to determine the method of delivery, which may lead to unnecessary cesarean procedures. These interventions can pose avoidable risks to both mother and child. A predictive system based on machine learning could offer a more objective, accurate approach by analyzing pre-labor clinical indicators. This project aims to develop such a model to classify childbirth mode, enabling timely and informed medical interventions.
Literature Review Summary
Research in maternal health analytics has demonstrated the potential of machine learning in medical predictions. Traditional algorithms such as logistic regression and decision trees offer a foundation for classification but struggle with complex, nonlinear relationships. More advanced ensemble models like Random Forest and XGBoost have shown superior accuracy in healthcare datasets. Additionally, feature selection and interpretation tools—such as SHAP SHapley Additive Explanations and Recursive Feature Elimination (RFE)—are essential for understanding the contribution of each clinical factor. Despite the promise of these methods, few studies combine algorithm comparison with interpretability, which this project addresses.
Dataset Overview
The dataset comprises anonymized records of pregnant individuals, with features representative of both maternal and fetal conditions. The structure is outlined below:

Key Insights
Fetal position and gestational age are the most significant predictors of delivery mode.
Ensemble learning models such as Random Forest and XGBoost outperform traditional algorithms in accuracy and robustness.
Feature selection enhances model interpretability and reduces overfitting, making results more clinically relevant.
Conclusion
The project successfully applies machine learning to predict the mode of childbirth with high accuracy and interpretability. The best-performing models, namely Random Forest and XGBoost, serve as effective decision support systems for obstetric care. Identifying critical clinical features aids in early planning and ensures safer delivery outcomes.
Future Work
Incorporate additional medical variables such as BMI, blood sugar levels, family history, and parity.
Leverage real-time monitoring data (e.g., uterine contractions, fetal movement) for dynamic prediction.
Develop a hospital-compatible application (web or mobile) for live deployment and usage in clinical settings.
