Although previous studies have identified genetic variants associated with PTD and gestational duration, their effect sizes remain relatively small, leaving a substantial portion of the hereditary variation unexplained. This thesis explores the potential of machine learning (ML) techniques to uncover additional insights into PTD and gestational duration using genetic data.  \nThe background section underscores the global impact of preterm birth on child mortality and long-term health outcomes, emphasising the role of genetics with an estimated heritability of around 30% . This project aims to apply ML techniques to improve the prediction of gestational duration and PTD based on genetic data. Research questions address ML model selection, the impact of variables on prediction performance, and a comparison to previous studies. The study is based on the Norwegian Mother, Father and Child Cohort Study (MoBa) and uses data from the Medical Birth Registry of Norway (MBRN) . The scope includes the use of genetic data and a focus on the 23 loci previously identified in a related study.  \nThe theory chapter provides an overview of genetics and its application in studying complex conditions like preterm delivery. It also introduces ML and explains the theoretical foundations of different ML models. Subsequently, the methods and materials chapter describes the data acquisition process, preprocessing steps, employed ML classifiers, and model evaluation methods. The chapter highlights the use of neural networks, classic ML algorithms, and libraries for implementation.  \nResults reveal varying AUC scores among classic models, with logistic regression (LR) performing the best. The choice of variables had a significant impact, with the maternal genome and the Top 23 set, offering the best conditions. Network models achieved comparative scores for binary classification. Additional analyses on the predicted probabilities demonstrated higher AUC scores compared to binary classifications, identifying RMSprop as the best-performing network model. The study reveals a slight improvement in results compared to Polygenic Risk Scores (PRS) but a modest predictive ","cbCaiqorTe5kdA3m","https://ap.wps.com/l/cbCaiqorTe5kdA3m","pdf",5837835,1,96,"English","en",105,"# Abstract\n## Background and Aim\n## Research Questions and Data\n## Theory and Methods\n## Results and Conclusions\n## Acknowledgements","[{\"question\":\"What problem does this thesis address?\",\"answer\":\"The thesis addresses prediction of preterm delivery and gestational duration, focusing on how genetic variation can improve predictive performance when earlier genetic effects explain only a limited portion of heritability.\"},{\"question\":\"Which dataset and genetic scope are used?\",\"answer\":\"The study uses data from the Norwegian Mother, Father and Child Cohort Study (MoBa) and the Medical Birth Registry of Norway (MBRN), focusing on genetic data and 23 loci previously identified in a related study.\"},{\"question\":\"Which machine learning approaches perform best?\",\"answer\":\"Logistic regression (LR) achieves the best overall AUC among classic models.
