I am Yongxin Guan (Kevin), a Year 3 student in the Bachelor of Science (Honours) in Data Science program at Beijing Normal-Hong Kong Baptist University (BNBU). My long-term goal is to pursue a PhD and build research that connects multimodal intelligence with practical deployment in real-world systems.
My current interests lie in AI for Science, world models, knowledge graphs, agent systems, reinforcement learning, and LLM enhancement across different domains. I enjoy working on problems that combine language, vision, structured knowledge, and robust engineering.
I am currently conducting research on multimodal relation extraction with large language models, knowledge graph completion for Graph RAG, and vision-based measurement systems. I am also open to research collaboration, internships, and opportunities where I can contribute to AI product building and applied machine learning.
My CV is available for download. You can also find me on GitHub and Kaggle.

Enhancing Multimodal Adversarial Transferability via Boundary-Context Augmentation
| ICCECT 2026 (Accepted) | Co-author | AI Security |
- Proposed the BCA-AET framework to improve adversarial robustness under different spatial layouts through boundary-context augmentation.
- Integrated image-text collaborative optimization to strengthen cross-modal attacks and improve transferability for VLP models in black-box settings.

TrustIE: Trustworthy Information Extraction via Joint Uncertainty Estimation and Evidence Attribution
| ICONIP 2026 (Accepted) | First Author | CCF-C |
- 2026.08: Accepted.
- FYP: Multimodal Relation Extraction with Large Language Models (Core Member, Supervisor: Dr. Rui Meng, Mar 2026 - Present). Designed multimodal prompt strategies for LLMs to fuse visual and textual features for relation extraction; built and pre-processed multimodal datasets and aligned image-text feature spaces. (Ongoing)
- Knowledge Graph Completion and Graph RAG (Recent Research Topic, Supervisor: Dr. Rui Meng). Evaluated and implemented KGC methods for link prediction and entity alignment; used KGC to strengthen Graph RAG pipelines, reduce hallucination, and improve reasoning quality in language models.
- Height Measurement Algorithm for Human Talent Identification and Development (Research Project, Supervisor: Dr. Ximing Shang). Developed a single-image visual algorithm for high-precision height measurement with human keypoint extraction, distortion and perspective correction.
