AGO: Boosting Mobile AI Inference Performance by Removing Constraints on Graph Optimization

no code implementations2 Dec 2022 Zhiying Xu, Hongding Peng, Wei Wang

Traditional deep learning compilers rely on heuristics for subgraph generation, which impose extra constraints on graph optimization, e. g., each subgraph can only contain at most one complex operator.

An Adaptive and Fast Convergent Approach to Differentially Private Deep Learning

no code implementations19 Dec 2019 Zhiying Xu, Shuyu Shi, Alex X. Liu, Jun Zhao, Lin Chen

ADADP significantly reduces the privacy cost by improving the convergence speed with an adaptive learning rate and mitigates the negative effect of differential privacy upon the model accuracy by introducing adaptive noise.

Reviewing and Improving the Gaussian Mechanism for Differential Privacy

no code implementations27 Nov 2019 Jun Zhao, Teng Wang, Tao Bai, Kwok-Yan Lam, Zhiying Xu, Shuyu Shi, Xuebin Ren, Xinyu Yang, Yang Liu, Han Yu

Although both classical Gaussian mechanisms [1, 2] assume $0 < \epsilon \leq 1$, our review finds that many studies in the literature have used the classical Gaussian mechanisms under values of $\epsilon$ and $\delta$ where the added noise amounts of [1, 2] do not achieve $(\epsilon,\delta)$-DP.
