报告题目：The Sampling Complexity of Phase Retrieval and Some Related Algorithms

腾讯会议ID: 897-121-032

报告摘要:The aim of phase retrieval is to recover signal from quadraticmeasurements. It is closely related to compressed sensing. However, the phase retrievalproblem is nonlinear and nonconvex. In this talk, we discuss the number of measurements for stably recovering signals from complex Gaussian quadratic measurements and Fourier measurements with random masks. Besides, we present some novel algorithm, which outperforms other state-of-art algorithms not only in sparse phase retrieval problem but also other fascinating related areas such as blind deconvolution problem.
