I am currently a fourth-year undergraduate student at Harbin Institute of Technology, Shenzhen(哈尔滨工业大学（深圳）) in Computer Science and Technology.

My research interest includes data mining, recommendation system, computer vision, and knowledge distillation(Graduation Project).

I have been involved in several research experiences, including next-poi recommendation in data mining, advised by Shanshan Feng(冯山山); hyperspectral anomaly detection in computer version, advised by Yongyong Chen(陈勇勇) and knowledge distillation in model compression, advised by Miao Zhang(张淼).

💻 Research Experience

Hyperspectral Anomaly Detection

2023.01 - 2023.06

Supervisor: Prof. Yongyong Chen(陈勇勇)

• Introduced a novel method for Hyperspectral Anomaly Detection using Multimodal Low-Rank Tensor Representation (MLTR), and improved the accuracy and generalization capabilities of HAD by employing a low-rank representation of multi-modal tensors.
• Outperformed previous methods on ten datasets and achieved a higher AUC, including the SanDiego dataset. Reduced the running time by approximately 20% compared to TLRSR.
• The paper is submitted to IEEE Geoscience and Remote Sensing Letters.

Next-POI Recommendation

2022.09 - 2023.04

Supervisor: Prof. Shanshan Feng(冯山山)

• Thoroughly reviewed all the papers, and successfully replicated the code from groundbreaking studies on Next-POI, published in 2021 and 2022. Gaining a basic understanding of the Next-POI field.
• Actively contributed to research group meetings, presenting relevant articles and sharing my insights, fostering a collaborative learning environment. Engaged in constructive discussions within the research group regarding potential enhancements to these models.
