Note We present MHG-GED, an autoencoder architecture that has an encoder based on GNN and a decoder based on a sequential model with MHG. Since the encoder is a GNN variant, MHG-GNN can accept any molecule as input, and demonstrate high predictive performance on molecular graph data. In addition, the decoder inherits the theoretical guarantee of MHG on always generating a structurally valid molecule as output.

Note SELFIES-TED introduces a transformer trained on SELFIES strings for improved molecule property prediction. SELFIES-TED uses a BART backbone to learn a molecule representation while also being able to generate novel molecules. SELFIES-TED has 2.2M parameters and was trained on >1 billion molecules from zinc-22, applying smiles enumeration.
