Scalable Incremental Nonconvex Optimization Approach for Phase Retrieval

Ji Li, Jian-Feng Cai, Hongkai Zhao

We aim to find a solution $\mathbf{x}\in {\mathbb{C}}^n$ to a system of quadratic equations of the form $b_i=|{\mathbf{a}}_i^{\ast }\mathbf{x}{|}^2$, $i=1,2,\dots ,m$, e.g., the well-known NP-har…
