Hidden Poison: Machine Unlearning Enables Camouflaged Poisoning Attacks
Jimmy Z. Di, Jack Douglas, Jayadev Acharya +2
We introduce camouflaged data poisoning attacks, a new attack vector that arises in the context of machine unlearning and other settings when model retraining may be induced. An ad…
Discrete Distribution Estimation under User-level Local Differential Privacy
Jayadev Acharya, Yuhan Liu, Ziteng Sun
We study discrete distribution estimation under user-level local differential privacy (LDP). In user-level -LDP, each user has samples and the privacy of all $…
The Role of Interactivity in Structured Estimation
Jayadev Acharya, Clément L. Canonne, Ziteng Sun +1
We study high-dimensional sparse estimation under three natural constraints: communication constraints, local privacy constraints, and linear measurements (compressive sensing). Wi…
Robust Estimation for Random Graphs
Jayadev Acharya, Ayush Jain, Gautam Kamath +2
We study the problem of robustly estimating the parameter of an Erdős-Rényi random graph on nodes, where a fraction of nodes may be adversarially corrupted. After showi…
Optimal Rates for Nonparametric Density Estimation under Communication Constraints
Jayadev Acharya, Clément L. Canonne, Aditya Vikram Singh +1
We consider density estimation for Besov spaces when each sample is quantized to only a limited number of bits. We provide a noninteractive adaptive estimator that exploits the spa…
Principal Bit Analysis: Autoencoding with Schur-Concave Loss
Sourbh Bhadane, Aaron B. Wagner, Jayadev Acharya
We consider a linear autoencoder in which the latent variables are quantized, or corrupted by noise, and the constraint is Schur-concave in the set of latent variances. Although fi…
