Auditing of Unlearning Algorithms
Sahasrajit Sarmasarkar, Anastasia Koloskova, Sanmi Koyejo
Evaluating whether unlearning algorithms truly remove training data influence remains an open challenge. We propose a practical auditor that computes data-dependent lower bounds on the unlearning parameter $\varepsilon$ using membership inference attacks. Evaluating multiple unle…
