A Communication-Efficient and Privacy-Aware Distributed Algorithm for Sparse PCA
Lei Wang, Xin Liu, Yin Zhang
Sparse principal component analysis (PCA) improves interpretability of the classic PCA by introducing sparsity into the dimension-reduction process. Optimization models for sparse…
A new compressive video sensing framework for mobile broadcast
Chengbo Li, Hong Jiang, Paul Wilford +2
A new video coding method based on compressive sampling is proposed. In this method, a video is coded using compressive measurements on video cubes. Video reconstruction is perform…
An Alternating Direction Algorithm for Matrix Completion with Nonnegative Factors
Yangyang Xu, Wotao Yin, Zaiwen Wen +1
This paper introduces an algorithm for the nonnegative matrix factorization-and-completion problem, which aims to find nonnegative low-rank matrices X and Y so that the product XY…
Alternating Direction Algorithms for -Problems in Compressive Sensing
Junfeng Yang, Yin Zhang
In this paper, we propose and study the use of alternating direction algorithms for several -norm minimization problems arising from sparse solution recovery in compressive…
