Protein Discovery with Discrete Walk-Jump Sampling

1 code implementation8 Jun 2023 Nathan C. Frey, Daniel Berenberg, Karina Zadorozhny, Joseph Kleinhenz, Julien Lafrance-Vanasse, Isidro Hotzel, Yan Wu, Stephen Ra, Richard Bonneau, Kyunghyun Cho, Andreas Loukas, Vladimir Gligorijevic, Saeed Saremi

We resolve difficulties in training and sampling from a discrete generative model by learning a smoothed energy function, sampling from the smoothed data manifold with Langevin Markov chain Monte Carlo (MCMC), and projecting back to the true data manifold with one-step denoising.

applications, we are sure to face an ever-mounting energy footprint to sustain these computational budgets, data storage needs, and more.

Graph Contrastive Learning for Materials

no code implementations24 Nov 2022 Teddy Koker, Keegan Quigley, Will Spaeth, Nathan C. Frey, Lin Li

By leveraging a series of material-specific transformations, we introduce CrystalCLR, a framework for constrastive learning of representations with crystal graph neural networks.

Benchmarking Resource Usage for Efficient Distributed Deep Learning

no code implementations28 Jan 2022 Nathan C. Frey, Baolin Li, Joseph McDonald, Dan Zhao, Michael Jones, David Bestor, Devesh Tiwari, Vijay Gadepally, Siddharth Samsi

Deep learning (DL) workflows demand an ever-increasing budget of compute and energy in order to achieve outsized gains.


FastFlows: Flow-Based Models for Molecular Graph Generation

3 code implementations28 Jan 2022 Nathan C. Frey, Vijay Gadepally, Bharath Ramsundar

We propose a framework using normalizing-flow based models, SELF-Referencing Embedded Strings, and multi-objective optimization that efficiently generates small molecules.

The Pseudo Projection Operator: Applications of Deep Learning to Projection Based Filtering in Non-Trivial Frequency Regimes

no code implementations13 Nov 2021 Matthew L. Weiss, Nathan C. Frey, Siddharth Samsi, Randy C. Paffenroth, Vijay Gadepally

Traditional frequency based projection filters, or projection operators (PO), separate signal and noise through a series of transformations which remove frequencies where noise is present.
