We generate a dataset of 1,554,012 labeled dipole moments using the DP-GEN scheme . The trained DW model shows an RMSE value of 0.071 (D) for an independently generated data set, outperforming the original deep Wannier study . Dipole moment distribution from the DPMD simulations (3.00 ± 0.29 (D)) aligns with experimental results and earlier AIMD studies .
