Parity plots for predicted bandgaps vs. GW bandgaps for PBE and HSE06 and two different ML models predicting GW corrections for either all bands (MAE = 0.18 eV) or only valence and conduction bands (MAE = 0.15 eV) which significantly outperform PBE and HSE06 with MAEs of 1.70 and 0.85 eV, respectively.
