Letian’s Academic Homepage ~ Be of good cheer!

I am a second Ph.D. student at UCSD, advised by Professor Jingbo Shang. Before Ph.D. I got my B.S. degree in Computer Science at SJTU, advised by Professor Hai Zhao.

Research Interest

My current focus is on the interaction between large language models (LLMs) with word/span/text embeddings. Followings are examples of questions I am interested in:

  1. (LLM-aided) Fancier Embedders: How to build embedders with LLMs to implment functions more than semantic similarity evaluation?
  2. LLMs as pitfalls detector: Are there undiscovered pitfalls in traditional embedders that can be detected by LLMs?
  3. Potential of Embedders: What are some undiscovered tasks that embeddings are much more efficent/effective than language models?
  4. LLM-oriented Retreival Augmentation: What kinds of embeddings for retrievers are prefered by LLMs, still by textual similarity?
