On the Necessity of Output Distribution Reweighting for Effective Class Unlearning

Ali Ebrahimpour-Boroojeny, Yian Wang, Hari Sundaram

In this paper, we reveal a significant shortcoming in class unlearning evaluations: overlooking the underlying class geometry can cause information leakage about the forgotten clas…

AMUN: Adversarial Machine UNlearning

Ali Ebrahimpour-Boroojeny, Hari Sundaram, Varun Chandrasekaran

Machine unlearning, where users can request the deletion of a forget dataset, is becoming increasingly important because of numerous privacy regulations. Initial works on ``exact''…

LOTOS: Layer-wise Orthogonalization for Training Robust Ensembles

Ali Ebrahimpour-Boroojeny, Hari Sundaram, Varun Chandrasekaran

Transferability of adversarial examples is a well-known property that endangers all classification models, even those that are only accessible through black-box queries. Prior work…

Spectrum Extraction and Clipping for Implicitly Linear Layers

Ali Ebrahimpour Boroojeny, Matus Telgarsky, Hari Sundaram

We show the effectiveness of automatic differentiation in efficiently and correctly computing and controlling the spectrum of implicitly linear operators, a rich family of layer ty…
