Stoichiometry Representation Learning with Polymorphic Crystal Structures

1 code implementation17 Nov 2023 Namkyeong Lee, Heewoong Noh, Gyoung S. Na, Tianfan Fu, Jimeng Sun, Chanyoung Park

Despite the recent success of machine learning (ML) in materials science, its success heavily relies on the structural description of crystal, which is itself computationally demanding and occasionally unattainable.

Representation Learning

Density of States Prediction of Crystalline Materials via Prompt-guided Multi-Modal Transformer

1 code implementation NeurIPS 2023 Namkyeong Lee, Heewoong Noh, Sungwon Kim, Dongmin Hyun, Gyoung S. Na, Chanyoung Park

While previous works mainly focus on obtaining high-quality representations of crystalline materials for DOS prediction, we focus on predicting the DOS from the obtained representations by reflecting the nature of DOS: DOS determines the general distribution of states as a function of energy.

Shift-Robust Molecular Relational Learning with Causal Substructure

1 code implementation29 May 2023 Namkyeong Lee, Kanghoon Yoon, Gyoung S. Na, Sein Kim, Chanyoung Park

To do so, we first assume a causal relationship based on the domain knowledge of molecular sciences and construct a structural causal model (SCM) that reveals the relationship between variables.

Relational Reasoning

Conditional Graph Information Bottleneck for Molecular Relational Learning

1 code implementation29 Apr 2023 Namkyeong Lee, Dongmin Hyun, Gyoung S. Na, Sungwon Kim, Junseok Lee, Chanyoung Park

Molecular relational learning, whose goal is to learn the interaction behavior between molecular pairs, got a surge of interest in molecular sciences due to its wide range of applications.

Predicting Density of States via Multi-modal Transformer

1 code implementation13 Mar 2023 Namkyeong Lee, Heewoong Noh, Sungwon Kim, Dongmin Hyun, Gyoung S. Na, Chanyoung Park

The density of states (DOS) is a spectral property of materials, which provides fundamental insights on various characteristics of materials.
