Subsequently, we constructed a fine-tuned NNP model using training data prepared through DFT-MD simulation of glasses with a variety of compositions. The NNP developed in this way was carefully validated in terms of the reproducibility of the energies and forces derived from DFT-MD. Further validation of NNP was performed on crystalline compounds and two-component glass systems for which experimentally reliable data have been reported, by means of local structures including borate superstructures. Four-or five-component oxide glasses were also modeled by NNMD, and the results were compared with experimental data. Finally, we modeled the second International Simple Glass (ISG-2), which is used as a reference nuclear waste glass in safety assessment studies.
