Privately Estimating a Gaussian: Efficient, Robust and Optimal
Daniel Alabi, Pravesh K. Kothari, Pranay Tankala +2
In this work, we give efficient algorithms for privately estimating a Gaussian distribution in both pure and approximate differential privacy (DP) models with optimal dependence on…
Efficient algorithms for certifying lower bounds on the discrepancy of random matrices
Prayaag Venkat
We initiate the study of the algorithmic problem of certifying lower bounds on the discrepancy of random matrices: given an input matrix , output a v…
Near-optimal fitting of ellipsoids to random points
Aaron Potechin, Paxton Turner, Prayaag Venkat +1
Given independent standard Gaussian points in dimension , for what values of does there exist with high probability an origin-symmetric ellipsoid tha…
Select and Permute: An Improved Online Framework for Scheduling to Minimize Weighted Completion Time
Samir Khuller, Jingling Li, Pascal Sturmfels +2
In this paper, we introduce a new online scheduling framework for minimizing total weighted completion time in a general setting. The framework is inspired by the work of Hall et a…
