Abstract: [en] Chemical space is estimated to contain over 10 60 small synthetically feasible molecules and so far only a fraction of the space has been explored. Experimental techniques are time-consuming and expensive so computational methods, such as machine learning, are needed for efficient exploration. Here we looked at generative models, more specifically variational autoencoder (VAE) and conditional variational autoencoder (CVAE), used for designing new molecules. In the first part, we evaluated already written VAE and in the second part, we upgraded it to the CVAE. For the conditional vectors in CVAE we used B4 Signatures generated from Chemical Checker describing molecular properties. Both models performed well, however, CVAE showed many advantages.
