Penalty Dual Decomposition Method For Nonsmooth Nonconvex Optimization
Qingjiang Shi, Mingyi Hong, Xiao Fu +1
Many contemporary signal processing, machine learning and wireless communication applications can be formulated as nonconvex nonsmooth optimization problems. Often there is a lack…
Joint Cooperative Computation and Interactive Communication for Relay-Assisted Mobile Edge Computing
Xihan Chen, Qingjiang Shi, Yunlong Cai +2
To realize cooperative computation and communication in a relay mobile edge computing system, we develop a hybrid relay forward protocol, where we seek to balance the execution del…
Block Coordinate Descent Only Converge to Minimizers
Enbin Song, Zhubin Shen, Qingjiang Shi
Given a non-convex twice continuously differentiable cost function with Lipschitz continuous gradient, we prove that all of block coordinate gradient descent, block mirror descent…
Learning to Optimize: Training Deep Neural Networks for Wireless Resource Management
Haoran Sun, Xiangyi Chen, Qingjiang Shi +3
For the past couple of decades, numerical optimization has played a central role in addressing wireless resource management problems such as power control and beamformer design. Ho…
