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…
