We evaluate continuity as follows: We encode 1000 random molecules from ZINC database to their respective latent variable z 0 . Then we perturb the latent variables by adding Gaussian noise with variance σ in a stepwise manner. Finally, we decode the perturbed variables to the respective molecules and measure the Tanimoto similarity between the new molecules and the original ones. The average Tanimoto similarity per step for various levels of noise variance σ is presented in Figure .
