CoCo: Coherence-Enhanced Machine-Generated Text Detection Under Data Limitation With Contrastive Learning

1 code implementation20 Dec 2022 Xiaoming Liu, Zhaohan Zhang, Yichen Wang, Hang Pu, Yu Lan, Chao Shen

Machine-Generated Text (MGT) detection, a task that discriminates MGT from Human-Written Text (HWT), plays a crucial role in preventing misuse of text generative models, which excel in mimicking human writing style recently.

Unify Local and Global Information for Top-$N$ Recommendation

1 code implementation3 Dec 2020 Xiaoming Liu, Shaocong Wu, Zhaohan Zhang, Chao Shen

To tackle this research gap, we propose a novel duet representation learning framework named \sysname to fuse local information (user-item interaction data) and global information (external knowledge graph) for the top-$N$ recommendation, which is composed of two separate sub-models.

Machine learning formation enthalpies of intermetallics

1 code implementation26 May 2020 Zhaohan Zhang, Mu Li, Katharine Flores, Rohan Mishra

The model uses easily accessible elemental properties as descriptors and has a mean absolute error (MAE) of 0. 025 eV/atom in predicting the formation enthalpy of stable binary intermetallics reported in the Materials Project database.
