TaP: A Taxonomy-Guided Framework for Automated and Scalable Preference Data Generation

Renren Jin, Tianhao Shen, Xinwei Wu +9

Conducting supervised and preference fine-tuning of large language models (LLMs) requires high-quality datasets to improve their ability to follow instructions and align with human…

Finding the Translation Switch: Discovering and Exploiting the Task-Initiation Features in LLMs

Xinwei Wu, Heng Liu, Xiaohu Zhao +6

Large Language Models (LLMs) frequently exhibit strong translation abilities, even without task-specific fine-tuning. However, the internal mechanisms governing this innate capabil…

ConTrans: Weak-to-Strong Alignment Engineering via Concept Transplantation

Weilong Dong, Xinwei Wu, Renren Jin +2

Ensuring large language models (LLM) behave consistently with human goals, values, and intentions is crucial for their safety but yet computationally expensive. To reduce the compu…

IRCAN: Mitigating Knowledge Conflicts in LLM Generation via Identifying and Reweighting Context-Aware Neurons

Dan Shi, Renren Jin, Tianhao Shen +3

It is widely acknowledged that large language models (LLMs) encode a vast reservoir of knowledge after being trained on mass data. Recent studies disclose knowledge conflicts in LL…

Exploring Multilingual Concepts of Human Value in Large Language Models: Is Value Alignment Consistent, Transferable and Controllable across Languages?

Shaoyang Xu, Weilong Dong, Zishan Guo +2

Prior research has revealed that certain abstract concepts are linearly represented as directions in the representation space of LLMs, predominantly centered around English. In thi…
