To be determined
Submitted to Journal of Cheminformatics

This work introduces an explainable and trustworthy machine learning framework for quality prediction in rubber mixing, combining XGBoost, explainability, and uncertainty quantification. The approach uncovers key process insights, reduces input complexity by 82%, and achieves high predictive accuracy — validated on real-world Michelin data.
