Despite increasing the training dataset size, we observed minimal improvement in the accuracy of the trained potential during the last training cycle. We hypothesized that this could be attributed to the complexity and significant diversity in energy among the data points (Figure ), which varied widely across a range of 4.52 eV/atom. After conducting multiple training sessions at different energy range values (as explained in section S1 and shown in Figures and), we identified the optimal dataset with an energy range of 2.0 eV/atom. Narrowing our attention to this energy range and further refining the data, we eliminated training data with a final dataset size of 14, 664. The detailed analysis of this dataset's composition, illustrating the distribution of data across various C/H ratios and the count of C atoms, is summarized in Fig. and
