Routing-Aware Expert Calibration for Machine Unlearning in Mixture-of-Experts Language Models

Jingyi Xie, Yijun Lin, Yinjiang Xiong +2

Machine unlearning is increasingly important for large language models, yet unlearning in Mixture-of-Experts (MoE) architectures remains underexplored. Unlike dense models, MoE arc…
