FIT to Forget: Robust Continual Unlearning for Large Language Models

Xiaoyu Xu, Minxin Du, Kun Fang +5

While large language models (LLMs) exhibit remarkable capabilities, they increasingly face demands to unlearn memorized privacy-sensitive, copyrighted, or harmful content. Existing…

From Domains to Instances: Dual-Granularity Data Synthesis for LLM Unlearning

Xiaoyu Xu, Minxin Du, Zitong Li +6

Although machine unlearning is essential for removing private, harmful, or copyrighted content from LLMs, current benchmarks often fail to faithfully represent the true ``forgettin…

Unlearning Isn't Deletion: Investigating Reversibility of Machine Unlearning in LLMs

Xiaoyu Xu, Xiang Yue, Yang Liu +5

Unlearning in large language models (LLMs) aims to remove specified data, but its efficacy is typically assessed with task-level metrics like accuracy and perplexity. We show that…

OBLIVIATE: Robust and Practical Machine Unlearning for Large Language Models

Xiaoyu Xu, Minxin Du, Qingqing Ye +1

Large language models (LLMs) trained over extensive corpora risk memorizing sensitive, copyrighted, or toxic content. To address this, we propose \textbf{OBLIVIATE}, a robust unlea…

Machine Unlearning of Pre-trained Large Language Models

Jin Yao, Eli Chien, Minxin Du +4

This study investigates the concept of the `right to be forgotten' within the context of large language models (LLMs). We explore machine unlearning as a pivotal solution, with a f…
