Researchers have developed a theoretical framework to address the challenge of machine unlearning within continual learning systems. This new objective function quantifies the trade-off between retaining past knowledge and effectively forgetting specific data. The study analyzes gradient-based and Hessian-based unlearning methods, finding that while gradient-based approaches have minimal storage overhead, Hessian-based methods are more effective at minimizing unlearning loss. This leads to a proposed hybrid strategy to balance performance and storage costs, with experimental results supporting the theoretical findings. AI
