Weijia Fan

Hi, there! I'm Weijia, currently a postgraduate student at the Computer Vision Institute (CVI), Shenzhen University, under the supervision of Professor Qiufu Li. The principal investigator (PI) of our institute is Professor Linlin Shen. My current research focuses on representation learning and visual recognition tasks. In the future, I aim to explore challenges in cross-modal learning and address alignment issues across different modalities using uniformity learning approaches.

I am actively seeking a Ph.D. position to further my research in large language models and cross-modal learning. If you find my profile interesting, please feel free to contact me via email fanweijia2023 at email dot szu dot edu dot cn.

I plan to be a visiting student from February 2025 to August 2025 and will make every effort to secure financial support.

If you are interested in connecting with me, feel free to reach out via email: fanweijia2023 at email dot szu dot edu dot cn / wakinghoursszu at outlook dot com.

BCE3S: Binary Cross-entropy based Tripartite Synergistic Learning for Long-tailed Recognition
Weijia Fan, Qiufu Li*, Jiajun Wen, Xiaoyang Peng, Linlin Shen
CVPR 2025 Conference Submission
We proposes a BCE-based tripartite synergistic learning method (BCE3S) that enhances feature compactness, classifier separability, and balance across head and tail classes in long-tailed recognition tasks, achieving high performance on unbalanced datasets.

EPL: Empirical Prototype Learning for Deep Face Recognition
Weijia Fan, Jiajun Wen, Xi Jia, Linlin Shen, Jiancan Zhou, Qiufu Li*
arxiv.org/2405.12447 Summited to Neurocomputing
We propose an Empirical Prototype Learning (EPL) method designed to mitigate performance degradation caused by hard samples tending to deviate the prototype away from the ideal class center.

Exploring thematic influences on theme park visitors' satisfaction: An empirical study on Disneyland China
Shizhen Bai, Hao He, Chunjia Han*, Mu Yang, Dingyao Yu, Xinrui Bi, Brij B. Gupta*, Weijia Fan, Prabin Kumar Panigrahi
Journal of Consumer Behaviour 23 (1), 90-106
we analyze user-generated data using structural topic modeling to explore the impact of themes on visitor satisfaction at Shanghai Disneyland, revealing dynamic changes in visitor focus and the diminishing correlation between reviews and ratings over time, offering valuable insights into consumer behavior and tourism research.

What makes a theme park experience less enjoyable? Evidence from online customer reviews of Disneyland China
Shizhen Bai, Hao He, Chunjia Han, Mu Yang*, Xinrui Bi,Weijia Fan
Frontiers in Psychology 14, 1120483
we leverage structural topic modeling and sentiment analysis on 112,000 reviews of Shanghai Disneyland to uncover key factors behind visitors’ dissatisfaction, providing insights into addressing issues like parking, service attitude, and entry processes to improve theme park management and visitor experience.
