Differentially Private Covariance Revisited

2 code implementations28 May 2022 Wei Dong, Yuting Liang, Ke Yi

In this paper, we present two new algorithms for covariance estimation under concentrated differential privacy (zCDP).

OneDConv: Generalized Convolution For Transform-Invariant Representation

no code implementations15 Jan 2022 Tong Zhang, Haohan Weng, Ke Yi, C. L. Philip Chen

Convolutional Neural Networks (CNNs) have exhibited their great power in a variety of vision tasks.

Frequency Estimation Under Multiparty Differential Privacy: One-shot and Streaming

no code implementations5 Apr 2021 Ziyue Huang, Yuan Qiu, Ke Yi, Graham Cormode

We study the fundamental problem of frequency estimation under both privacy and communication constraints, where the data is distributed among $k$ parties.

Optimal Sparsity-Sensitive Bounds for Distributed Mean Estimation

1 code implementation NeurIPS 2019 Zengfeng Huang, Ziyue Huang, Yilei Wang, Ke Yi

We consider the problem of estimating the mean of a set of vectors, which are stored in a distributed system.

Communication-Efficient Weighted Sampling and Quantile Summary for GBDT

no code implementations17 Sep 2019 Ziyue Huang, Ke Yi

Gradient boosting decision tree (GBDT) is a powerful and widely-used machine learning model, which has achieved state-of-the-art performance in many academic areas and production environment.

An Information-Theoretic Approach to Detecting Changes in Multi-Dimensional Data Streams

1 code implementation INFORMS 2006 Tamraparni Dasu, Shankar Krishnan, Suresh Venkatasubramanian, Ke Yi

In this paper, we take a general, information-theoretic approach to the change detection problem, which works for multidimensional as well as categorical data.
