🎓About Me

I am an assistant professor at Hefei University of Technology. Before that, I was graduated from the School of Computer Science and Technology, University of Science and Technology of China (USTC) (中国科学技术大学计算机与信息学院) with a bachelor’s degree and doctor’s degree, advised by Enhong Chen (陈恩红). I also collaborate with Qi Liu (刘淇) from University of Science and Technology of China (USTC), Le Wu (吴乐) from Hefei University of Technology (HFUT), Xing Xie (谢幸) from Microsoft Research Asia. I have been selected for the 2022 MSRA StarTrack Scholar, won the Chinese Academy of Sciences President’s Award 2019, and winner of the KDD 2018 Best Student Paper Award.

My research interests include Semantic Representation, Large Language Models, Causal Reasoning and Debiased Learning, Recommender System. I have published 30+ papers on SIGIR, ACL, WWW, AAAI, etc. If you are seeking any form of academic cooperation, please feel free to email me.

I am also looking forward self-motivated students to join us. If you are interested in my research, feel free to contact me.

Sentence Semantic Representation

AAAI 2019

DRr-Net: Dynamic Re-Read Network for Sentence Semantic Matching

Kun Zhang, Guangyi Lv, Linyuan Wang, Le Wu, Enhong Chen, Fangzhao Wu, and Xing Xie

• This work draws inspiration from cognitive psychology and designs dynamic attention mechanism (DRr-Net) to realize the focusing and dynamic adjustment of attention, improving the quality of generated sentence representations.
• This work is also extend to IEEE TNNLS2022.

IEEE TNNLS2023

Description-Enhanced Label Embedding Contrastive Learning for Text Classification

Kun Zhang, Le Wu, Guangyi Lv, Enhong Chen, Shulan Ruan, Jing Liu, Zhiqiang Zhang, Jun Zhou, Meng Wang

• The previous work R$^2$-Net has been accepted by AAAI 2021
• This work proposed a novel self-supervised learning framework to make full use of label information to achieve high-quality sentence representation generation and relation inference.

Causal Inference-based Debiasing

AI Open 2024

Label-aware Debiased Causal Reasoning for Natural Language Inference

Kun Zhang*, Dacao Zhang, Le Wu, Richang Hong, Ye Zhao, Meng Wang, AI Open.

• This work proposes that label information can be used to guide the spurious correlation identification. Thus, it treats label information as one variable in causal graph and utilizes counterfactual inference to remove the spurious correlations introduced by human annotations.Finally, it realize debiased and robust natural language inference.
• We also extend this work into multi-modal scenarios and public one high-quality paper in Journal of Computer Research and Development.
