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…
