Fig. 2: Ablation studies for GST-ACE-24.
a Fraction of successful runs in high-temperature annealing tests for each iteration of the potential. Three structural models from different tests are shown, with atoms colour-coded by minimum bond length: red colour indicates atoms with very short distances to their nearest neighbour, which might lead to lost atoms in molecular-dynamics simulations. b An ablation study for the number of random structures present in the training data, evaluated based on the fraction of successful high-T annealing runs. The success rate was obtained across 7 different Ge–Sb–Te compositions, from GeTe to Sb2Te3, with each composition including 10 independent high-T annealing runs.
