I'm a Ph.D. student at the University of Washington, advised by Professor Dongfang Zhao. My research focuses on database systems and information retrieval, with an emphasis on efficient indexing and retrieval for vector databases.
Research Areas: Database Systems, Data Management, Information Retrieval, Indexing
Current Research
I am currently researching advanced indexing and search techniques.
VectorSearch is a hybrid vector retrieval system that integrates semantic embeddings, multi-vector search, and hybrid indexing to improve retrieval accuracy and query efficiency through optimized index design and dynamic vector management.
NexusIndex integrates multi-model embeddings, attention mechanisms, and a FAISSNexusIndex layer to support efficient fake news detection via dynamic vector indexing and real-time retrieval across textual and visual data.
VecLSTM: Trajectory Data Processing and Management for Activity Recognition through LSTM Vectorization and Database Integration
VecLSTM integrates dynamic vectorization with a CNN–LSTM architecture to process trajectory data efficiently within a relational database environment, improving accuracy and training time compared to traditional LSTM models.
This research introduces a caching subsystem leveraging in-memory vector databases to improve image feature extraction efficiency. The framework integrates batch insertion and parallel processing to optimize performance.
This research focused on using deep neural networks and hierarchical clustering to predict chaotic transitions in natural convection systems, specifically in the Lorenz system.
