About Me

I am a Ph.D. candidate in the School of Humanities at Tsinghua University. My major is computational linguistics, combining artificial intelligence and natural languages. I am interested in computational lexical semantics (including polysemy, ambiguity and uncertainty) and AI interpretability.

Talks

  • To know, or not to know? Language, Uncertainty and Artificial Intelligence

    At Shanxi University of Finance and Economnics, June 12th, [PPT]

    In this talk, I reviewed my recent research from a philosophical perspective of epistemology: What does the model not know? (Known Knowns) What does the model unknow? (Known Unknowns).

  • Evaluation agentiveness of Subject-object reversible sentences in LLMs

    At a linguistic seminar, November 26th, [PPT]

    In this talk, I employ difference vetors in LLMs to represent agentiveness of different components (SVO) in a reversible but meaning-preserving sentence pair.
