A new paper analyzes machine unlearning techniques, particularly for second-order optimizers, finding current definitions may be insufficient. The research compares first-order and second-order optimizers in data deletion tasks, noting that while both methods show performance and gradient alignment, second-order optimizers exhibit state volatility. This volatility suggests residual information that first-order analysis might miss, indicating a need for controlled state perturbation to fully erase geometric information. AI
IMPACT Highlights potential gaps in current machine unlearning methods for advanced optimizers, suggesting new research directions for data privacy.
