arXiv:2606.03808v1 Announce Type: new Abstract: We propose PURGE, a machine unlearning algorithm built on a simple but an under-exploited observation: continual learning (CL) and machine unlearning (MU) which are fundamentally dual problems. CL tries to learn new tasks without forgetting old ones; MU tries to erase specific data without hurting retained performance representing the same underlying tension in opposite directions. PURGE leverages this duality by adapting gradient projection from A-GEM (Chaudhry et al., 2019) so that every unlearning step is constrained to not increase the retain
The increasing focus on data privacy regulations and the need for adaptable machine learning models drives the development of efficient unlearning techniques.
This research provides a more efficient and theoretically grounded method for machine unlearning, crucial for regulatory compliance and enhancing trust in AI systems.
Machine unlearning, traditionally a complex and computation-heavy task, becomes more practical and less disruptive to retained model performance.

PURGE directly improves the feasibility and performance of machine unlearning in AI systems.
This advancement could lead to broader adoption of unlearning mechanisms, making AI models more compliant and robust to data changes.
The duality between continual learning and unlearning might unlock further innovations in adaptive and ethical AI model development.
