This paper studies how machine learning models can predict and optimize fiber diameter in ZnO-PVP nanofibers produced by electrospinning, using an experimental dataset that varies PVP concentration, flow rate, needle tip-to-collector distance, and applied voltage. The authors compare multiple linear regression, support vector regression, and XGBoost, reporting that SVR achieved the best predictive performance (R² = 0.97, accuracy = 0.96). Explainable-AI feature importance analyses (F-scores, SHAP, and permutation importance) consistently identify PVP concentration as the most influential factor, followed by flow rate and voltage, with distance having minimal impact. The paper is a preprint and not peer reviewed, and it does not state additional limitations in the provided text. The paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract The electrospinning technique is crucial for synthesizing zinc oxide (ZnO) nanofibers within a polyvinylpyrrolidone (PVP) polymer matrix, where precise control over fiber diameter is essential for optimizing functional properties. This study investigates the application of Machine Learning (ML) methods, including Multiple Linear Regression (MLR), Support Vector Regression (SVR), and XGBoost, to model and optimize key electrospinning parameters: PVP concentration, flow rate, needle tip-to-collector distance, and applied voltage, aiming to produce uniform nanofibers with minimal diameters. A systematic experimental dataset was generated to capture fiber diameter variations under different parameter settings. Among the models evaluated, SVR demonstrated the best predictive performance, achieving an R² score of 0.97 with accuracy of 0.96, indicating its effectiveness in capturing the complex nonlinear relationships inherent to the electrospinning process. Feature importance analysis using F-scores, SHAP values, and permutation importance consistently identified PVP concentration as the most influential factor, followed by flow rate and voltage, while distance showed minimal impact. The proposed ML-based predictive modeling framework offers a data-driven approach to fine-tune electrospinning conditions, enabling greater precision and efficiency in the fabrication of ZnO-PVP nanofibers.
