Overview
I am currently pursuing a PhD degree in the College of Computer Science and Technology at Zhejiang University in China. My research interests revolve around vector similarity search, proximity graph-based index, and vector databases.
My current research focuses on the following topics:
- Graph-Based Approximate Nearest Neighbor Search
- DRAM&SSD-Based Approximate Nearest Neighbor Search
- Complex Approximate Nearest Neighbor Search (e.g., hybrid query)
- Mutimodal Search
