Phase retrieval of low-rank matrices by anchored regression
Phase retrieval of low-rank matrices by anchored regression
Abstract We study the low-rank phase retrieval problem, where our goal is to recover a $d_1\times d_2$ low-rank matrix from a series of phaseless linear measurements. This is a fourth-order inverse problem, as we are trying to recover factors of a matrix that have been observed, indirectly, through some quadratic …
