Special Issue Information

Dear Colleagues,

Machine learning (ML) has become a powerful tool in advancing predictive modeling and optimization, especially within the manufacturing sector. The Special Issue "Machine Learning for Predictive Modeling and Optimization of Manufacturing Processes" aims to gather cutting-edge research focused on the development and application of ML techniques to improve efficiency, quality, and decision-making in manufacturing processes.

This Special Issue invites contributions that explore innovative machine learning methodologies, optimization frameworks, and real-world implementations specifically targeted at manufacturing applications. Topics of interest include but are not limited to supervised and unsupervised learning, deep learning architectures, reinforcement learning, ensemble models, feature engineering, and explainable AI as applied to manufacturing systems.

We particularly encourage submissions addressing challenges such as process parameter prediction, defect detection, process control, energy optimization, predictive maintenance, and smart manufacturing. Contributions related to data preprocessing, model interpretability, and ML-integrated decision support systems tailored to manufacturing are also welcome.

Through this Special Issue, we aim to promote interdisciplinary collaboration and foster novel insights into how ML can revolutionize manufacturing processes. We welcome original research articles, comprehensive reviews, and practical case studies that contribute to this rapidly evolving field.

Accurate prediction of key environmental parameters is crucial for intelligent control and optimization, yet it remains challenging due to gradient instability in deep learning models, like Long Short-Term Memory (LSTM), during time series forecasting. This study introduces a novel adaptive optimization algorithm, NadamClip, which integrates gradient clipping directly into the Nadam framework to address the trade-off between convergence efficiency and gradient explosion. NadamClip incorporates an adjustable gradient clipping threshold strategy that permits manual tuning. Through systematic experiments, we identified an optimal threshold range that effectively balances model performance and training stability, dynamically adapting to the evolving convergence characteristics of the network across different training phases. Aquaculture systems are regarded as similar to modern biomanufacturing systems. The study evaluated an aquaculture dataset for ammonia concentration prediction in aquaculture environmental control processes. NadamClip achieved outstanding results on key metrics, including a Root Mean Square Error (RMSE) of 0.2644, a Mean Absolute Error (MAE) of 0.6595, and a Coefficient of Determination (R2) score of 0.9743. Compared to existing optimizer enhancements, NadamClip pioneers the integration of gradient clipping with adaptive momentum estimation, overcoming the traditional paradigm where clipping primarily serves as an external training control rather than an intrinsic algorithmic component. This study provides a practical and reproducible optimization framework for intelligent modeling of dynamic process systems, thereby contributing to the broader advancement of machine learning methods in predictive modeling and optimization for data-driven manufacturing and environmental processes.
