Simultaneously Achieving Sublinear Regret and Constraint Violations for Online Convex Optimization with Time-varying Constraints
Qingsong Liu, Wenfei Wu, Longbo Huang +1
In this paper, we develop a novel virtual-queue-based online algorithm for online convex optimization (OCO) problems with long-term and time-varying constraints and conduct a perfo…
Double Quantization for Communication-Efficient Distributed Optimization
Yue Yu, Jiaxiang Wu, Longbo Huang
Modern distributed training of machine learning models suffers from high communication overhead for synchronizing stochastic gradients and model parameters. In this paper, to reduc…
Learning-aided Stochastic Network Optimization with Imperfect State Prediction
Longbo Huang, Minghua Chen, Yunxin Liu
We investigate the problem of stochastic network optimization in the presence of imperfect state prediction and non-stationarity. Based on a novel distribution-accuracy curve predi…
Time-Average Optimization with Non-Convex Decision Set and Its Convergence
Sucha Supittayapornpong, Longbo Huang, Michael J. Neely
This paper considers time-average optimization, where a decision vector is chosen every time step within a (possibly non-convex) set, and the goal is to minimize a convex function…
System Intelligence: Model, Bounds and Algorithms
Longbo Huang
We present a general framework for understanding system intelligence, i.e., the level of system smartness perceived by users, and propose a novel metric for measuring intelligence…
Optimizing Age-of-Information in a Multi-class Queueing System
Longbo Huang, Eytan Modiano
We consider the age-of-information in a multi-class queueing system, where each class generates packets containing status information. Age of information is a relatively ne…
