Baselines. We compare our model to several state-of-the-art molecular generation models. First, MoFlow by Zang and Wang which is the native flow model that our generator is built upon and therefore equivalent to the objective described in where α = ρ = 0. We also compare our model performance to previous normalizing flow models Graph AF , GraphNVP , and Graph Residual Flow (GRF) . In the realm of GANs and VAEs we compare our model to MolGAN , ORGAN and NeVAE .
