Allegro-Legato: Scalable, Fast, and Robust Neural-Network Quantum Molecular Dynamics via Sharpness-Aware Minimization

1 code implementation14 Mar 2023 Hikaru Ibayashi, Taufeq Mohammed Razakh, Liqiu Yang, Thomas Linker, Marco Olguin, Shinnosuke Hattori, Ye Luo, Rajiv K. Kalia, Aiichiro Nakano, Ken-ichi Nomura, Priya Vashishta

Specifically, Allegro-Legato exhibits much weaker dependence of timei-to-failure on the problem size, $t_{\textrm{failure}} \propto N^{-0. 14}$ ($N$ is the number of atoms) compared to the SOTA Allegro model $\left(t_{\textrm{failure}} \propto N^{-0. 29}\right)$, i. e., systematically delayed time-to-failure, thus allowing much larger and longer NNQMD simulations without failure.

Multiscale Graph Neural Networks for Protein Residue Contact Map Prediction

no code implementations2 Dec 2022 Kuang Liu, Rajiv K. Kalia, Xinlian Liu, Aiichiro Nakano, Ken-ichi Nomura, Priya Vashishta, Rafael Zamora-Resendizc

Machine learning (ML) is revolutionizing protein structural analysis, including an important subproblem of predicting protein residue contact maps, i. e., which amino-acid residues are in close spatial proximity given the amino-acid sequence of a protein.

Physics-informed Neural-Network Software for Molecular Dynamics Applications

no code implementations6 Nov 2020 Taufeq Mohammed Razakh, Beibei Wang, Shane Jackson, Rajiv K. Kalia, Aiichiro Nakano, Ken-ichi Nomura, Priya Vashishta

We have developed a novel differential equation solver software called PND based on the physics-informed neural network for molecular dynamics simulators.
