In a reaction network energetics, the largest errors can influence the conclusions most. The coefficients from the sparsified linear regression are provided in the brackets in Table . As mentioned before, these coefficients were obtained by performing a linear regression after taking the subsets of bonds for which the coefficients were ≥ 0.1 eV when all bonds were included in the linear regression. The coefficients after the sparsification are similar to the previous coefficients, which indicate consistency of the method. Therefore, our method can be further extended to a more diversified dataset where the number of bonds may be so higher that sparsification is necessary. with G4MP2, PBE, B3LYP-D, and M06-2X. For the DFT methods, the reaction energies for both using SCF and post-SCF methods (indicated as a subscript) are provided with and without correction. The reaction energies with the correction are provided with the subscript 'corr'.
