On the Outage Probability Conjecture for MIMO Channels
Gen Li, Jingkai Yan, Yuantao Gu
Multiple-Input-Multiple-Output (MIMO) communication systems have seen wide application due to its performance benefits such as multiplexing gain. For MIMO systems with non-ergodic…
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…
Nonconvex Sparse Logistic Regression with Weakly Convex Regularization
Xinyue Shen, Yuantao Gu
In this work we propose to fit a sparse logistic regression model by a weakly convex regularized nonconvex optimization problem. The idea is based on the finding that a weakly conv…
Cross-label Suppression: A Discriminative and Fast Dictionary Learning with Group Regularization
Xiudong Wang, Yuantao Gu
This paper addresses image classification through learning a compact and discriminative dictionary efficiently. Given a structured dictionary with each atom (columns in the diction…
Linearized ADMM for Non-convex Non-smooth Optimization with Convergence Analysis
Qinghua Liu, Xinyue Shen, Yuantao Gu
Linearized alternating direction method of multipliers (ADMM) as an extension of ADMM has been widely used to solve linearly constrained problems in signal processing, machine lean…
