Table 4 Ablation study to investigate the impact of unit cell offset encoding (UCOE) and bond-level data uncertainty (BLDU) estimation on model performance. The performances are evaluated by the MAE of coordinates (Å), bond length (Å), lattice (Å), and cell volume (Å3) between the predicted and DFT-relaxed structures
