The mean absolute error was calculated for each model by comparing the experimental results from the training set with the predicted values. The models predicting dimer HOMO, LUMO and Eg energies in this experiment are summarized in Table . The equation and summary of the OLS results for each model are given in Tables S2 -S7 of the supporting information.
