论边信息在战略传播中的作用

On the Role of Side Information In Strategic Communication

Emrah Akyol, Cedric Langbort, Tamer Basar

摘要:

本文分析了网络环境中战略沟通的根本局限性。战略传播不同于信息理论中的传统传播范式,因为它涉及编码者和解码者的不同目标,编码者和解码者意识到这种不匹配并相应地采取行动。这导致了一个Stackelberg游戏,其中两个代理都事先承诺他们的映射。基于我们以前的点对点设置工作,本文研究了接收器和/或发射器侧信息设置的压缩和通信问题。均衡策略和相关成本的特点是高斯变量与二次成本函数。分析了在这种策略环境下信源和联合信源-信道编码中边信息的优势问题。我们的分析揭示了一个有趣的结果最优性的未编码映射的战略源信道编码网络。

英文摘要:

This paper analyzes the fundamental limits of strate- gic communication in network settings. Strategic communication differs from the conventional communication paradigms in in- formation theory since it involves different objectives for the encoder and the decoder, which are aware of this mismatch and act accordingly. This leads to a Stackelberg game where both agents commit to their mappings ex-ante. Building on our prior work on the point-to-point setting, this paper studies the compression and communication problems with the receiver and/or transmitter side information setting. The equilibrium strategies and associated costs are characterized for the Gaussian variables with quadratic cost functions. Several questions on the benefit of side information in source and joint source-channel coding in such strategic settings are analyzed. Our analysis has uncovered an interesting result on optimality of uncoded mappings in strategic source-channel coding in networks.
