About
I am a forth-year Ph.D student at the University of Hong Kong (HKU), majoring in Computer Science, supervised by Professor Yiu Siu-Ming. My research focuses on optimizing graph-based models, including GCNs, contrastive learning, transformers, diffusion models, reinforcement learning, and LLMs. By exploring underlying principles and mathematical frameworks, I develop innovative algorithms that effectively leverage the structural properties of graph/image data. This approach enhances accuracy, scalability, and interpretability. For example, I advance our understanding of graph algorithms in spatial-temporal graphs, recommendation systems, and bioinformatics.
Graph Data Mining
Spatial-Temporal Graphs (AI for Urban Science)
