Fréchet ChemNet Distance: A metric for generative models for molecules in drug design—Supporting Information—

S1 Determination of necessary data set size of generated molecules to reliable estimate the mean m and covariance C ofthegeneratedsamples........... 3 S2 FCD for real molecules stemming from different databases. The title indicates the used reference set. The bars show the mean FCD of the different real molecule sets and the baseline. The real molecules exhibit a lower FCD compared to the baseline independent of the reference set...................... 4 S3 ArchitectureofChemNet.............................. 6
