Cascading Blackout Severity Prediction with Statistically-Augmented Graph Neural Networks

no code implementations22 Mar 2024 Joe Gorka, Tim Hsu, Wenting Li, Yury Maximov, Line Roald

Higher variability in grid conditions, resulting from growing renewable penetration and increased incidence of extreme weather events, has increased the difficulty of screening for scenarios that may lead to catastrophic cascading failures.

Spectroscopy-Guided Discovery of Three-Dimensional Structures of Disordered Materials with Diffusion Models

1 code implementation9 Dec 2023 Hyuna Kwon, Tim Hsu, Wenyu Sun, Wonseok Jeong, Fikret Aydin, James Chapman, Xiao Chen, Matthew R. Carbone, Deyu Lu, Fei Zhou, Tuan Anh Pham

In this work, we introduce a new framework based on the diffusion model, a recent generative machine learning method to predict 3D structures of disordered materials from a target property.

Score dynamics: scaling molecular dynamics with picoseconds timestep via conditional diffusion model

1 code implementation2 Oct 2023 Tim Hsu, Babak Sadigh, Vasily Bulatov, Fei Zhou

Our current SD implementation is about two orders of magnitude faster than the MD counterpart for the systems studied in this work.

Score-based denoising for atomic structure identification

1 code implementation5 Dec 2022 Tim Hsu, Babak Sadigh, Nicolas Bertin, Cheol Woo Park, James Chapman, Vasily Bulatov, Fei Zhou

We propose an effective method for removing thermal vibrations that complicate the task of analyzing complex dynamics in atomistic simulation of condensed matter.

Microstructure Generation via Generative Adversarial Network for Heterogeneous, Topologically Complex 3D Materials

no code implementations22 Jun 2020 Tim Hsu, William K. Epting, Hokon Kim, Harry W. Abernathy, Gregory A. Hackett, Anthony D. Rollett, Paul A. Salvador, Elizabeth A. Holm

Using a large-scale, experimentally captured 3D microstructure dataset, we implement the generative adversarial network (GAN) framework to learn and generate 3D microstructures of solid oxide fuel cell electrodes.
