NS-RGS: Newton-Schulz based Riemannian gradient method for orthogonal group synchronization
Haiyang Peng, Deren Han, Xin Chen +1
Group synchronization is a fundamental task involving the recovery of group elements from pairwise measurements. For orthogonal group synchronization, the most common approach refo…
The Condition Number in Phase Retrieval from Intensity Measurements
Haiyang Peng, Deren Han, Meng Huang
This paper investigates the stability of phase retrieval by analyzing the condition number of the nonlinear map $Ψ_{\boldsymbol{A}}(\boldsymbol{x}) = \bigl(\lvert \langle {\boldsym…
Noisy phase retrieval from subgaussian measurements
Haiyang Peng, Deren Han, Linbin Li +1
This paper aims to address the phase retrieval problem from subgaussian measurements with arbitrary noise, with a focus on devising robust and efficient algorithms for solving non-…
On pseudoinverse-free randomized methods for linear systems: Unified framework and acceleration
Deren Han, Jiaxin Xie
We present a new framework for the analysis and design of randomized algorithms for solving various types of linear systems, including consistent or inconsistent, full rank or rank…
