Compositional Deep Probabilistic Models of DNA Encoded Libraries

no code implementations20 Oct 2023 Benson Chen, Mohammad M. Sultan, Theofanis Karaletsos

DNA-Encoded Library (DEL) has proven to be a powerful tool that utilizes combinatorially constructed small molecules to facilitate highly-efficient screening assays.

DEL-Dock: Molecular Docking-Enabled Modeling of DNA-Encoded Libraries

1 code implementation30 Nov 2022 Kirill Shmilovich, Benson Chen, Theofanis Karaletsos, Mohammad M. Sultan

Computational models have been deployed to learn the latent binding affinities that are correlated to the sequenced count data; however, this correlation is often obfuscated by various sources of noise introduced in its complicated data-generation process.

Fragment-based Sequential Translation for Molecular Optimization

no code implementations NeurIPS Workshop AI4Scien 2021 Benson Chen, Xiang Fu, Regina Barzilay, Tommi Jaakkola

Equipped with the learned fragment vocabulary, we propose Fragment-based Sequential Translation (FaST), which learns a reinforcement learning (RL) policy to iteratively translate model-discovered molecules into increasingly novel molecules while satisfying desired properties.

Optimal Transport Graph Neural Networks

2 code implementations8 Jun 2020 Benson Chen, Gary Bécigneul, Octavian-Eugen Ganea, Regina Barzilay, Tommi Jaakkola

Current graph neural network (GNN) architectures naively average or sum node embeddings into an aggregated graph representation -- potentially losing structural or semantic information.
