Differentially Private Deep Learning with Direct Feedback Alignment

no code implementations8 Oct 2020 Jaewoo Lee, Daniel Kifer

Standard methods for differentially private training of deep neural networks replace back-propagated mini-batch gradients with biased and noisy approximations to the gradient.

Scaling up Differentially Private Deep Learning with Fast Per-Example Gradient Clipping

no code implementations7 Sep 2020 Jaewoo Lee, Daniel Kifer

The reason for this slowdown is a crucial privacy-related step called "per-example gradient clipping" whose naive implementation undoes the benefits of batch training with GPUs.

Stochastic Adaptive Line Search for Differentially Private Optimization

no code implementations18 Aug 2020 Chen Chen, Jaewoo Lee

In this paper, we introduce a stochastic variant of classic backtracking line search algorithm that satisfies R\'enyi differential privacy.

Renyi Differentially Private ADMM for Non-Smooth Regularized Optimization

no code implementations18 Sep 2019 Chen Chen, Jaewoo Lee

In this paper we consider the problem of minimizing composite objective functions consisting of a convex differentiable loss function plus a non-smooth regularization term, such as $L_1$ norm or nuclear norm, under R\'enyi differential privacy (RDP).

Concentrated Differentially Private Gradient Descent with Adaptive per-Iteration Privacy Budget

1 code implementation28 Aug 2018 Jaewoo Lee, Daniel Kifer

It outperforms prior algorithms for model fitting and is competitive with the state-of-the-art for $(\epsilon,\delta)$-differential privacy, a strictly weaker definition than zCDP.

Differentially Private Confidence Intervals for Empirical Risk Minimization

no code implementations11 Apr 2018 Yue Wang, Daniel Kifer, Jaewoo Lee

The process of data mining with differential privacy produces results that are affected by two types of noise: sampling noise due to data collection and privacy noise that is designed to prevent the reconstruction of sensitive information.
