A successive difference-of-convex method for a class of two-stage nonconvex nonsmooth stochastic conic program via SVI
Chao Zhang, Di Wang
We consider a class of two-stage nonconvex nonsmooth stochastic conic program, where the objective functions in both stages can contain nonsmooth terms that are functions with easi…
Pricing for Information Revelation in Demand Response: A Strategic Communication Approach
Hassan Mohamad, Chao Zhang, Samson Lasaulce +4
Many smart grid frameworks, such as demand response programs, require accurate information about consumers' parameters (e.g., flexibility) at the aggregator side to optimize grid o…
Goal-oriented compression for -norm-type goal functions: Application to power consumption scheduling
Yifei Sun, Hang Zou, Chao Zhang +2
Conventional data compression schemes aim at implementing a trade-off between the rate required to represent the compressed data and the resulting distortion between the original a…
Improving MIMO channel estimation via receive power feedback
Chao Zhang, Hang Zou, Samson Lasaulce +1
Estimating the channel state is known to be an important problem in wireless networks. To this end, it matters to exploit all the available information to improve channel estimatio…
Goal-Oriented Communications for the IoT and Application to Data Compression
Chao Zhang, Hang Zou, Samson Lasaulce +3
Internet of Things (IoT) devices will play an important role in emerging applications, since their sensing, actuation, processing, and wireless communication capabilities stimulate…
Goal-Oriented Quantization: Analysis, Design, and Application to Resource Allocation
Hang Zou, Chao Zhang, Samson Lasaulce +2
In this paper, the situation in which a receiver has to execute a task from a quantized version of the information source of interest is considered. The task is modeled by the mini…
A refined consumer behavior model for energy systems: Application to the pricing and energy-efficiency problems
Chao Zhang, Samson Lasaulce, Li Wang +2
The sum-utility maximization problem is known to be important in the energy systems literature. The conventional assumption to address this problem is that the utility is concave.…
Decision-making Oriented Clustering: Application to Pricing and Power Consumption Scheduling
Chao Zhang, Samson Lasaulce, Martin Hennebel +3
Data clustering is an instrumental tool in the area of energy resource management. One problem with conventional clustering is that it does not take the final use of the clustered…
Analysis of the tradeoff between health and economic impacts of the Covid-19 epidemic
Samson Lasaulce, Chao Zhang, Vineeth Varma +1
Various measures have been taken in different countries to mitigate the Covid-19 epidemic. But, throughout the world, many citizens don't understand well how these measures are tak…
Decision-Oriented Communications: Application to Energy-Efficient Resource Allocation
Hang Zou, Chao Zhang, Samson Lasaulce +2
In this paper, we introduce the problem of decision-oriented communications, that is, the goal of the source is to send the right amount of information in order for the intended de…
Task Oriented Channel State Information Quantization
Hang Zou, Chao Zhang, Samson Lasaulce
In this paper, we propose a new perspective for quantizing a signal and more specifically the channel state information (CSI). The proposed point of view is fully relevant for a re…
Using Continuous Power Modulation for Exchanging Local Channel State Information
Chao Zhang, Samson Lasaulce, Vineeth S. Varma
This letter provides a simple but efficient technique, which allows each transmitter of an interference network, to exchange local channel state information with the other transmit…
Interference Coordination via Power Domain Channel Estimation
Chao Zhang, Vineeth Varma, Samson Lasaulce +1
A novel technique is proposed which enables each transmitter to acquire global channel state information (CSI) from the sole knowledge of individual received signal power measureme…
