The Local Landscape of Phase Retrieval Under Limited Samples

no code implementations26 Nov 2023 Kaizhao Liu, ZiHao Wang, Lei Wu

We next consider the one-point strong convexity and show that as long as $n=\omega(d)$, with high probability, the landscape is one-point strongly convex in the local annulus: $\{w\in\mathbb{R}^d: o_d(1)\leqslant \|w-w^*\|\leqslant c\}$, where $w^*$ is the ground truth and $c$ is an absolute constant.
