Unlearning as multi-task optimization: A normalized gradient difference approach with an adaptive learning rate

Zhiqi Bu, Xiaomeng Jin, Bhanukiran Vinzamuri +4

Machine unlearning has been used to remove unwanted knowledge acquired by large language models (LLMs). In this paper, we examine machine unlearning from an optimization perspectiv…

LUME: LLM Unlearning with Multitask Evaluations

Anil Ramakrishna, Yixin Wan, Xiaomeng Jin +6

Unlearning aims to remove copyrighted, sensitive, or private content from large language models (LLMs) without a full retraining. In this work, we develop a multi-task unlearning b…
