Derivative-Free Methods for Policy Optimization: Guarantees for Linear Quadratic Systems
Dhruv Malik, Ashwin Pananjady, Kush Bhatia +3
We study derivative-free methods for policy optimization over the class of linear policies. We focus on characterizing the convergence rate of these methods when applied to linear-…
Towards Optimal Estimation of Bivariate Isotonic Matrices with Unknown Permutations
Cheng Mao, Ashwin Pananjady, Martin J. Wainwright
Many applications, including rank aggregation, crowd-labeling, and graphon estimation, can be modeled in terms of a bivariate isotonic matrix with unknown permutations acting on it…
Breaking the Barrier: Faster Rates for Permutation-based Models in Polynomial Time
Cheng Mao, Ashwin Pananjady, Martin J. Wainwright
Many applications, including rank aggregation and crowd-labeling, can be modeled in terms of a bivariate isotonic matrix with unknown permutations acting on its rows and columns. W…
