Consistency-Aware Editing for Entity-level Unlearning in Language Models

Xiaoqi Han, Víctor Gutiérrez-Basulto, Ru Li +3

Large language models (LLMs) risk retaining sensitive, copyrighted, or harmful information from their training data. Entity-level unlearning addresses this issue by removing all kn…

Explaining Black-box Language Models with Knowledge Probing Systems: A Post-hoc Explanation Perspective

Yunxiao Zhao, Hao Xu, Zhiqiang Wang +3

Pre-trained Language Models (PLMs) are trained on large amounts of unlabeled data, yet they exhibit remarkable reasoning skills. However, the trustworthiness challenges posed by th…
