PCOS Risk Prediction: Integrated Algorithm Approach

Abstract

A significant challenge in women’s health is posed by Polycystic Ovary Syndrome (PCOS) because it is a difficult disorder to comprehend and exhibits various symptoms. This research project suggests the creation of a computerized predic- tion scheme for PCOS using machine learning algorithms and bioinformatics tools. The aim of this system is to give personalized risk assessment to women thus enabling early detection, and proactive management of PCOS. It combines other intelligible probabilities about PCOS with the use of user provided health data with Machine Learning models such as Random Forest, Logistic Regression, Support Vector Machine, Naive Bayes, Radial SVM, Linear SVM and KNeighbours Classifier. Addition- ally, it provides intuitive predictions regarding PCOS likelihood through ML models, which are based on Random Forest, Logistic Regression, Support Vector Machine (SVM), Naive Bayes (NB), Radial SVM (RSVM), Linear SVM (LSVM) and KNeighbours Classifier (KNC). By way of thorough assessment as well as comparison within these models the system intends to improve precision together with reliability during prediction of PCOS. The major objective is therefore to enable timely intervention along with individualized healthcare strategies that will promote better health outcomes for all women.

Introduction

I. INTRODUCTION

Polycystic ovary syndrome (PCOS) is among the most common endocrine disorders among women of reproductive age worldwide. It is characterized by hormonal imbalance, ab- normal menstrual periods and growth of cysts in ovaries mak- ing diagnosis, management and treatment of PCOS complex. The reproductive impacts are not the only concern but also metabolic, cardiovascular and psychological wellbeing thus it puts significant economic and social burden on individuals as well as healthcare systems.

[1]There are still many obstacles in timely detection and management of PCOS despite its high incidence rate. This problem is often diagnosed using traditional methods involving physical examinations, laboratory tests and imaging such as ultrasound scan that may give results which are not conclusive or untimely. Therefore, dealing with a complex condition like PCOS requires delivering healthcare services that have more sophisticated approaches that are individually crafted for each patient because of its heterogeneous presentation.

[7]In response to these challenges, this research project proposes the development of a novel PCOS prediction system leveraging advanced machine learning (ML) algorithms and bioinformatics techniques. By harnessing the power of ML, this system aims to enhance the accuracy and efficiency of PCOS risk assessment, ultimately empowering women with personalized insights into their reproductive health.

The primary objective of this research endeavor is twofold: first, to develop a robust predictive model capable of accurately assessing an individual’s likelihood of developing PCOS based on a comprehensive range of health parameters; and second, to integrate this predictive model into an intuitive user interface, enabling seamless interaction and accessibility for individuals seeking personalized health insights.

In the subsequent sections of this paper, we will delve into the methodology employed for developing the PCOS prediction system, including the selection and evaluation of ML algorithms, data collection, preprocessing techniques, and system design considerations. Furthermore, we will discuss the potential implications of this research for PCOS diagnosis, management, and healthcare delivery, as well as avenues for future research and development in this vital area of women’s health. Through this interdisciplinary approach, we aim to contribute to the advancement of personalized medicine and improved outcomes for individuals affected by PCOS.

[2]The study titled “A Machine Learning Approach for Early Prediction of Polycystic Ovary Syndrome” by Smith et al. is concerned with the pressing need to detect PCOS early, which is a common hormonal disorder in women of childbearing age.

The research applies machine learning tech- niques such as logistic regression and random forest to forecast PCOS using extensive clinical and hormone data analysis. It combines various datasets on patient demographics, medical history, and hormone levels to make models that capture the multifaceted nature of PCOS indicators. This primary aim will enable risk identification for proactive management and intervention among those who are more likely to develop the condition later on in life. In this work, machine learning was used for timely PCOS prediction through empirical investi- gations and verification assessments that indicate promising results regarding accuracy rates, sensitivity index, specificity rates as well as AUC-ROC values. Early PCOS detection has far-reaching consequences including better patient out- comes, reduced healthcare spending and improved lives for the affected people at large. As a whole, this study highlights how data-driven approaches can change both identification of PCOS and its control which would provide valuable findings into women‘s health area.
