Researchers have developed the first theoretical framework to address the challenge of machine unlearning within continual learning (CL) systems. This new framework characterizes the trade-off between retaining existing knowledge and effectively forgetting specific data in models that continuously update. The study proposes adapting existing unlearning methods, like gradient-based and Hessian-based approaches, to CL, highlighting that gradient-based methods offer lower storage overhead despite potentially lower effectiveness in forgetting. This suggests a hybrid strategy to balance performance and storage costs, which was validated through experiments. AI
