 # Model card -- PolymerBlocks
 
-**Model Details**: *PolymerBlocks* is a sequence-based molecular generator tuned to generate blocks of polymers (e.g., catalysts and monomers). The model relies on a Variational Autoencoder architecture as described in [Born et al. (2021; *iScience*)](https://www.sciencedirect.com/science/article/pii/S2589004221002376)

+**Information about training algorithms, parameters, fairness constraints or other applied approaches, and features**: the sequence-based model is a standard GRU-based VAE trained to reconstruct SMILES representation of molecules. Given the nature of the pre-training and fine-tuning data, the model is biased to create molecules that resemble catalysts and monomers employed in ring-opening polymerization.
