Table 1.

Performance Benchmarks on OQMD. The table shows the mean absolute error (MAE), and root mean squared error (RMSE) for the baseline and proposed models on 10% of the data that was randomly sampled and withheld as a test set. The bracketed numbers show the standard deviation in the last significant figure.
