FactKG: Fact Verification via Reasoning on Knowledge Graphs

Jiho Kim, Sungjin Park, Yeonsu Kwon +3

In real world applications, knowledge graphs (KG) are widely used in various domains (e.g. medical applications and dialogue agents). However, for fact verification, KGs have not b…

Do Language Models Understand Measurements?

Sungjin Park, Seungwoo Ryu, Edward Choi

Recent success of pre-trained language models (PLMs) has stimulated interest in their ability to understand and work with numbers. Yet, the numerical reasoning over measurements ha…

Unconditional Image-Text Pair Generation with Multimodal Cross Quantizer

Hyungyung Lee, Sungjin Park, Joonseok Lee +1

Although deep generative models have gained a lot of attention, most of the existing works are designed for unimodal generation. In this paper, we explore a new method for uncondit…

Off-centered Pb interstitials in PbTe

Sungjin Park, Jongho Park, Byungki Ryu +1

In this work, we calculate the defect properties of low-symmetry Pb interstitials in PbTe using first-principles density-functional theory calculations. We break the symmetry impos…

Semi-supervised Disentanglement with Independent Vector Variational Autoencoders

Bo-Kyeong Kim, Sungjin Park, Geonmin Kim +1

We aim to separate the generative factors of data into two latent vectors in a variational autoencoder. One vector captures class factors relevant to target classification tasks, w…

Hybrid-functional and quasi-particle calculations of band structures of Mg2Si, Mg2Ge, and Mg2Sn

Byungki Ryu, Sungjin Park, Eun-Ae Choi +4

We perform hybrid functional and quasi-particle band structure calculations with spin-orbit interaction to investigate the band structures of Mg2Si, Mg2Ge, and Mg2Sn. For all Mg2X…
