I am a second-year Ph.D student in Data Science and Analytics (DSA) thrust at HKUST, where I am very fortunately supervised by Prof. Sunghun KIM and Prof. Raymond Chi Wing WONG.

I graduated from College of Internet of Things Engineering, Hohai University (河海大学物联网工程学院) with a bachelor’s degree and from the School of Electronic and Computer Engineering, Peking University (北京大学信息工程学院) with a master’s degree, advised by Prof.Yuexian Zou. I also collaborate with Prof.Shoujin Wang from University of Technology Sydney closely.

My research interest includes sequential recommendation, medical NLP and large language models. I have published 15+ papers at the top international AI conferences such as ACL, NeurIPS, IJCAI, SIGIR, WWW, CIKM, RecSys, ICASSP.

I am now working on Large Language Models + RecSys/Healthcare. If you are seeking any form of academic collaboration or would like to be an Intern/RA (3-6 months) within our group, please feel free to email me at zhoupalin@gmail.com.

Is ChatGPT a Good Recommender? A Preliminary Study
Junling Liu, Chao Liu, Peilin Zhou, Renjie Lv, Kang Zhou, Yan Zhang.

  • First work to utilize ChatGPT as a universal recommender, assessing its capabilities across five tasks.
  • Provides valuable insights into the strengths and limitations of ChatGPT in recommendation systems.

🔁 Sequential Recommendation

SIGIR 2022

Decoupled Side Information Fusion for Sequential Recommendation
Yueqi Xie, Peilin Zhou, Sunghun Kim

  • Motivation: The early integration of various types of embeddings limits the expressiveness of attention matrices due to a rank bottleneck and constrains the flexibility of gradients.
  • Solution: Move the side information from the input to the attention layer and decouples the attention calculation of various side information and item representation.

Attention Calibration for Transformer-based Sequential Recommendation
Peilin Zhou, Qichen Ye, Yueqi Xie, Jingqi Gao, and Sunghun Kim.

  • AC-TSR framework can reduce the impact of sub-optimal position encoding and noisy input on the existing transformer-based SRS models with limited overhead.
  • Two plug-and-play calibrators, namely spatial calibrator and adversarial calibrator, are designed to rectify the unreliable attention.

Equivariant Contrastive Learning for Sequential Recommendation
Peilin Zhou, Jingqi Gao, Yueqi Xie, Qichen Ye, et al.

  • Motivation: some augmentation strategies, such as item substitution, can lead to changes in user intent. Learning indiscriminately invariant representations for all augmentation strategies might be sub-optimal.
  • Solution: we propose Equivariant Contrastive Learning for Sequential Recommendation (ECL-SR), which endows SR models with great discriminative power, making the learned user behavior representations sensitive to invasive augmentations and insensitive to mild augmentations.

METS-CoV: A Dataset of Medical Entity and Targeted Sentiment on COVID-19 Related Tweets
Peilin Zhou, Zeqiang Wang, Dading Chong, Zhijiang Guo, et al.

  • Introduce METS-CoV, the first dataset to include medical entities and targeted sentiments on COVID-19-related tweets.
  • METS-CoV fully considers the characteristics of the medical field and can therefore be used to help researchers use natural language processing models to mine valuable medical information from tweets.
  • Annotation guidelines, benchmark models, and source code are released for medical social medial research.

🧬 Large Languages Models for Healthcare

Benchmarking Large Language Models on CMExam–A Comprehensive Chinese Medical Exam Dataset
Junling Liu, Peilin Zhou, Yining Hua, Dading Chong, et al.

  • We construct CMExam, a dataset sourced from the stringent Chinese National Medical Licensing Examination, featuring 60,000+ multiple-choice questions, with detailed explanations.
  • This study aims to spur further exploration of LLMs in medicine by providing a comprehensive benchmark for their evaluation.
Under Review
