Researchers have developed a new auditing method to evaluate the effectiveness of machine learning unlearning algorithms. This auditor uses membership inference attacks to compute data-dependent lower bounds on the unlearning parameter $\varepsilon$. The study found that algorithms with formal guarantees, like model clipping and rewind-to-delete, performed well, while empirical methods showed poor unlearning results. This framework offers a practical way to empirically test and potentially falsify claims about unlearning. AI
