Distributed Online Private Learning of Convex Nondecomposable Objectives

no code implementations16 Jun 2022 Huqiang Cheng, Xiaofeng Liao, Huaqing Li

For such problems, we first design a novel generic algorithm framework, named as DPSDA, of differentially private distributed online learning using the Laplace mechanism and the stochastic variants of dual averaging method.

Local Black-box Adversarial Attacks: A Query Efficient Approach

no code implementations4 Jan 2021 Tao Xiang, Hangcheng Liu, Shangwei Guo, Tianwei Zhang, Xiaofeng Liao

Based on this property, we identify the discriminative areas of a given clean example easily for local perturbations.
