Representations and Mechanisms in Language Models
We analyze how models encode, organize, and retrieve linguistic knowledge to explain capability formation and model behavior.
计算语言学与意识科学实验室
We study how human language is used, understood, learned, and evolved across time scales and dynamic environments, using computational methods to explore the deep connections among language, intelligence, and consciousness.
We are actively recruiting self-motivated graduate, undergraduate students, and post-docs.
We analyze how models encode, organize, and retrieve linguistic knowledge to explain capability formation and model behavior.
We study reasoning paths, structured generation, and capability boundaries to develop more effective and interpretable reasoning methods.
We study when models know, when they do not, and how confidence and knowledge boundaries can support appropriate responses under uncertainty.
We use spectral, statistical, and psycholinguistic signals to detect machine-generated text and evaluate generation quality and human preference.
We study how models store, forget, and update information while maintaining long-term memory and adapting to new knowledge in continual settings.
We connect psycholinguistics, eye tracking, behavioral experiments, and computational models to compare human and machine language processing.
First-authored by our Ph.D. student Hao An, the paper proposes FiSCoRe, jointly fine-tuning models with correctness and semantic-entropy uncertainty.
