Fig. 7: Scaling behavior of bandgap prediction loss as the number of target samples is increased.

a, b The results for HOIP-GeF and HOIP-PbI, respectively. The results of E2T and MPNN-Linear are distinguished by blue and orange colors, respectively. The x-axis denotes the number of target samples used for fine-tuning, whereas the y-axis denotes the RMSE of the bandgap predictions along with the standard deviations.
