Linear Convergence of Distributed Compressed Optimization with Equality Constraints
Zihao Ren, Lei Wang, Zhengguang Wu +1
In this paper, the distributed strongly convex optimization problem is studied with spatio-temporal compressed communication and equality constraints. For the case where each agent…
Distributed Optimization by Network Flows with Spatio-Temporal Compression
Zihao Ren, Lei Wang, Xinlei Yi +5
Several data compressors have been proposed in distributed optimization frameworks of network systems to reduce communication overhead in large-scale applications. In this paper, w…
Distributed Adaptive Time-Varying Optimization with Global Asymptotic Convergence
Liangze Jiang, Zheng-Guang Wu, Lei Wang
In this note, we study distributed time-varying optimization for a multi-agent system. We first focus on a class of time-varying quadratic cost functions, and develop a new distrib…
Distributed Least-Squares Optimization Solvers with Differential Privacy
Weijia Liu, Lei Wang, Fanghong Guo +2
This paper studies the distributed least-squares optimization problem with differential privacy requirement of local cost functions, for which two differentially private distribute…
Distributed Continuous-Time Optimization with Uncertain Time-Varying Quadratic Cost Functions
Liangze Jiang, Zheng-Guang Wu, Lei Wang
This paper studies distributed continuous-time optimization for time-varying quadratic cost functions with uncertain parameters. We first propose a centralized adaptive optimizatio…
Differentially Private Average Consensus with Improved Accuracy-Privacy Trade-off
Lei Wang, Weijia Liu, Fanghong Guo +2
This paper studies the average consensus problem with differential privacy of initial states, for which it is widely recognized that there is a trade-off between the mean-square co…
