A Convex Optimization Approach to High-Dimensional Sparse Quadratic Discriminant Analysis
T. Tony Cai, Linjun Zhang
In this paper, we study high-dimensional sparse Quadratic Discriminant Analysis (QDA) and aim to establish the optimal convergence rates for the classification error. Minimax lower…

The Cost of Privacy: Rates of Convergence for Parameter Estimation with Differential Privacy
T. Tony Cai, Yichen Wang, Linjun Zhang
We study the minimax cost of -differential privacy for mean estimation and Gaussian linear regression in low and high dimensions. For low-dimensional mean estimati…
