Expander Graph and Communication-Efficient Decentralized Optimization
Yat-Tin Chow, Wei Shi, Tianyu Wu +1
In this paper, we discuss how to design the graph topology to reduce the communication complexity of certain algorithms for decentralized optimization. Our goal is to minimize the…
Decentralized Consensus Optimization with Asynchrony and Delays
Tianyu Wu, Kun Yuan, Qing Ling +2
We propose an asynchronous, decentralized algorithm for consensus optimization. The algorithm runs over a network in which the agents communicate with their neighbors and perform l…
Cyclic Coordinate Update Algorithms for Fixed-Point Problems: Analysis and Applications
Yat Tin Chow, Tianyu Wu, Wotao Yin
Many problems reduce to the fixed-point problem of solving . To this problem, we apply the coordinate-update algorithms, which update only one or a few components of at…
Coordinate Friendly Structures, Algorithms and Applications
Zhimin Peng, Tianyu Wu, Yangyang Xu +2
This paper focuses on coordinate update methods, which are useful for solving problems involving large or high-dimensional datasets. They decompose a problem into simple subproblem…
Design and Analysis of Multi-User SDMA Systems with Noisy Limited CSIT Feedback
Tianyu Wu, Vincent K. N. Lau
In this paper, we consider spatial-division multiple-access (SDMA) systems with one base station with multiple antennae and a number of single antenna mobiles under noisy limited C…
A Low-Overhead Energy Detection Based Cooperative Sensing Protocol for Cognitive Radio Systems
Shunqing Zhang, Tianyu Wu, Vincent K. N. Lau
Cognitive radio and dynamic spectrum access represent a new paradigm shift in more effective use of limited radio spectrum. One core component behind dynamic spectrum access is the…
