Atom-by-atom protein generation and beyond with language models

no code implementations16 Aug 2023 Daniel Flam-Shepherd, Kevin Zhu, Alán Aspuru-Guzik

However, they are constrained to generate proteins with only the set of amino acids represented in their vocabulary.

Language models can generate molecules, materials, and protein binding sites directly in three dimensions as XYZ, CIF, and PDB files

no code implementations9 May 2023 Daniel Flam-Shepherd, Alán Aspuru-Guzik

In doing so, we demonstrate that it is not necessary to use simplified molecular representations to train chemical language models -- that they are powerful generative models capable of directly exploring chemical space in three dimensions for very different structures.

Scalable Fragment-Based 3D Molecular Design with Reinforcement Learning

no code implementations1 Feb 2022 Daniel Flam-Shepherd, Alexander Zhigalin, Alán Aspuru-Guzik

We introduce a novel RL framework for scalable 3D design that uses a hierarchical agent to build molecules by placing molecular substructures sequentially in 3D space, thus attempting to build on the existing human knowledge in the field of molecular design.

Keeping it Simple: Language Models can learn Complex Molecular Distributions

1 code implementation6 Dec 2021 Daniel Flam-Shepherd, Kevin Zhu, Alán Aspuru-Guzik

In this work, we investigate the capacity of simple language models to learn distributions of molecules.

Learning quantum dynamics with latent neural ODEs

1 code implementation20 Oct 2021 Matthew Choi, Daniel Flam-Shepherd, Thi Ha Kyaw, Alán Aspuru-Guzik

The core objective of machine-assisted scientific discovery is to learn physical laws from experimental data without prior knowledge of the systems in question.

Learning Interpretable Representations of Entanglement in Quantum Optics Experiments using Deep Generative Models

1 code implementation6 Sep 2021 Daniel Flam-Shepherd, Tony Wu, Xuemei Gu, Alba Cervera-Lierta, Mario Krenn, Alan Aspuru-Guzik

The complex relationship between the setup structure of a quantum experiment and its entanglement properties is essential to fundamental research in quantum optics but is difficult to intuitively understand.

Neural Message Passing on High Order Paths

no code implementations24 Feb 2020 Daniel Flam-Shepherd, Tony Wu, Pascal Friederich, Alan Aspuru-Guzik

Graph neural network have achieved impressive results in predicting molecular properties, but they do not directly account for local and hidden structures in the graph such as functional groups and molecular geometry.
