Communication Efficient Distributed Newton Method with Fast Convergence Rates

Chengchang Liu, Lesi Chen, Luo Luo +1

We propose a communication and computation efficient second-order method for distributed optimization. For each iteration, our method only requires $O (d)$ communication c…

Symmetric Rank- $k$ Methods

Chengchang Liu, Cheng Chen, Luo Luo

This paper proposes a novel class of block quasi-Newton methods for convex optimization which we call symmetric rank- $k$ (SR- $k$ ) methods. Each iteration of SR- $k$ incorporates the…
