A compressive multi-kernel method for privacy-preserving machine learning

no code implementations20 Jun 2021 Thee Chanyaswad, J. Morris Chang, S. Y. Kung

Compressive Privacy is a privacy framework that employs utility-preserving lossy-encoding scheme to protect the privacy of the data, while multi-kernel method is a kernel based machine learning regime that explores the idea of using multiple kernels for building better predictors.

A Differential Privacy Mechanism Design Under Matrix-Valued Query

1 code implementation26 Feb 2018 Thee Chanyaswad, Alex Dytso, H. Vincent Poor, Prateek Mittal

noise to each element of the matrix, this method is often sub-optimal as it forfeits an opportunity to exploit the structural characteristics typically associated with matrix analysis.

MVG Mechanism: Differential Privacy under Matrix-Valued Query

no code implementations2 Jan 2018 Thee Chanyaswad, Alex Dytso, H. Vincent Poor, Prateek Mittal

To address this challenge, we propose a novel differential privacy mechanism called the Matrix-Variate Gaussian (MVG) mechanism, which adds a matrix-valued noise drawn from a matrix-variate Gaussian distribution, and we rigorously prove that the MVG mechanism preserves $(\epsilon,\delta)$-differential privacy.

Coupling Random Orthonormal Projection with Gaussian Generative Model for Non-Interactive Private Data Release

1 code implementation31 Aug 2017 Thee Chanyaswad, Changchang Liu, Prateek Mittal

A key challenge facing the design of differential privacy in the non-interactive setting is to maintain the utility of the released data.
