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.
