The objective of this research is to improve the early detection of Polycystic Ovary Syndrome (PCOS) focusing on the challenge of early detection of PCOS and its profound implications for reproductive health. PCOS, a prevalent endocrine disorder affecting millions of women worldwide, presents a significant hurdle to achieving pregnancy due to elevated infertility rates. Recognizing the urgent need for accurate diagnostic tools, we employ advanced machine learning, deep learning, and ensemble modeling techniques on the Polycystic Ovary Syndrome (PCOS) dataset by Prasoon Kottarathil (Polycystic ovary syndrome (PCOS), Version 3, 2020. https://www.kaggle.com/datasets/prasoonkottarathil/polycystic-ovary-syndrome-pcos ) which comprises of clinical data gathered from 10 different hospitals across Kerala, India, including 541 women patients split into 2 different groups- One who had PCOS and fertility issues, while, on the other hand, there were women who had PCOS but didn't have fertility issues. Our approach includes machine learning models like support vector machine, random forest regression, logistic regression, XGBoost regression, and gradient boosting regression, alongside ensemble techniques like blending and stacking, and deep learning model feedforward neural network coupled with ExtraTree classifier for feature selection and data balancing techniques like ADASYN and ENN from comprehensive clinical parameters. The blending ensemble model which consisted of an ensemble of random forest regression, XGBoost regression, and gradient boosting regression was our highest-performing model with 98.03% accuracy along with a precision value of 0.981, recall value of 0.983, and F1-score of 0.979. This research heralds a future where early detection of PCOS fosters informed decision-making and fosters improved reproductive outcomes.
