Linear Convergence of An Iterative Phase Retrieval Algorithm with Data Reuse
Gen Li, Yuchen Jiao, Yuantao Gu
Phase retrieval has been an attractive but difficult problem rising from physical science, and there has been a gap between state-of-the-art theoretical convergence analyses and th…
Active Orthogonal Matching Pursuit for Sparse Subspace Clustering
Yanxi Chen, Gen Li, Yuantao Gu
Sparse Subspace Clustering (SSC) is a state-of-the-art method for clustering high-dimensional data points lying in a union of low-dimensional subspaces. However, while opt…
Restricted Isometry Property of Gaussian Random Projection for Finite Set of Subspaces
Gen Li, Yuantao Gu
Dimension reduction plays an essential role when decreasing the complexity of solving large-scale problems. The well-known Johnson-Lindenstrauss (JL) Lemma and Restricted Isometry…
Phase Transitions of Spectral Initialization for High-Dimensional Nonconvex Estimation
Yue M. Lu, Gen Li
We study a spectral initialization method that serves a key role in recent work on estimating signals in nonconvex settings. Previous analysis of this method focuses on the phase r…
