Complete and Efficient Graph Transformers for Crystal Material Property Prediction

1 code implementation18 Mar 2024 Keqiang Yan, Cong Fu, Xiaofeng Qian, Xiaoning Qian, Shuiwang Ji

Crystal structures are characterized by atomic bases within a primitive unit cell that repeats along a regular lattice throughout 3D space.

Efficient Approximations of Complete Interatomic Potentials for Crystal Property Prediction

1 code implementation12 Jun 2023 Yuchao Lin, Keqiang Yan, Youzhi Luo, Yi Liu, Xiaoning Qian, Shuiwang Ji

This is enabled by our approximations of infinite potential summations, where we extend the Ewald summation for several potential series approximations with provable error bounds.

GraphEBM: Towards Permutation Invariant and Multi-Objective Molecular Graph Generation

no code implementations29 Sep 2021 Meng Liu, Keqiang Yan, Bora Oztekin, Shuiwang Ji

In this work, we propose GraphEBM, a molecular graph generation method via energy-based models (EBMs), as an exploratory work to perform permutation invariant and multi-objective molecule generation.

GraphEBM: Molecular Graph Generation with Energy-Based Models

1 code implementation ICLR Workshop EBM 2021 Meng Liu, Keqiang Yan, Bora Oztekin, Shuiwang Ji

We note that most existing approaches for molecular graph generation fail to guarantee the intrinsic property of permutation invariance, resulting in unexpected bias in generative models.
