Solving Phase Retrieval via Graph Projection Splitting
Ji Li, Hongkai Zhao
Phase retrieval with prior information can be cast as a nonsmooth and nonconvex optimization problem. We solve the problem by graph projection splitting (GPS), where the two proxim…
Scalable Incremental Nonconvex Optimization Approach for Phase Retrieval
Ji Li, Jian-Feng Cai, Hongkai Zhao
We aim to find a solution to a system of quadratic equations of the form , , e.g., the well-known NP-har…
On Relaxed Averaged Alternating Reflections (RAAR) Algorithm for Phase Retrieval from Structured Illuminations
Ji Li, Tie Zhou
In this paper, as opposed to the random phase masks, the structured illuminations with a pixel-dependent deterministic phase shift are considered to derandomize the model setup. Th…
Numerical Optimization Algorithm of Wavefront Phase Retrieval from Multiple Measurements
Ji Li, Tie Zhou
Wavefront phase retrieval from a set of intensity measurements can be formulated as an optimization problem. Two nonconvex objective models (MLP and its variants LS) based on maxim…
On Gradient Descent Algorithm for Generalized Phase Retrieval Problem
Ji Li, Tie Zhou
In this paper, we study the generalized phase retrieval problem: to recover a signal from the measurements $y_r=\lvert \langle\bm{a}_r,\bm{x}\rangle\rvert^2…
