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 $x \in C^{n}$ to a system of quadratic equations of the form $b_{i} = ∣ a_{i}^{*} x ∣^{2}$ , $i = 1, 2, \dots, m$ , e.g., the well-known NP-har…
