Abstract

This paper presents a novel approach to glass composition screening through a self-supervised learning framework, addressing the challenges posed by glass transition temperature (Tg) prediction. Given the critical role of Tg in determining glass performance across various applications, we reformulate the composition screening task as a classification problem, allowing for direct prediction of whether specific compositional samples fall within a designated Tg range. Our model leverages advanced self-supervised learning techniques to optimize for the area under the curve (AUC) metric, mitigating the adverse effects of noise and class imbalances in training data. We introduce a data augmentation method based on the law of large numbers to enhance sample size and improve noise robustness. Additionally, our DeepGlassNet backbone encoder captures intricate second-order and higher-order interactions among components, providing insights into their collective impact on glass properties. We validate our approach using data from the SciGlass database, demonstrating its capability to accurately predict Tg for compositions within the specified range, while also exploring extrapolation to untested samples. This work not only enhances the accuracy of glass composition screening but also offers scalable solutions applicable to material screening across various fields, thereby advancing the development of novel materials.
