AI总结:

针对6G语义通信中黑盒机器学习导致的理论与实践脱节问题,本文基于语义熵、语义失真和通信速率等信息论指标刻画信息流,并提出兼顾可解释性与有效性的实施指南。

摘要:

随着流量数据的指数级激增以及新兴智能应用对超低时延的迫切需求,可以预见,6G网络将需要颠覆性通信技术,以在人类社会中培育泛在智能与简洁性。语义通信作为一种新型范式,有望通过仅传输与任务相关的信息,显著削减通信开销与时延。尽管语义通信在理论框架和实际实现方面已有大量努力,但显著的理论与实践差距使其理论分析和解释变得复杂,尤其是在采用黑盒机器学习技术时。本文首先深入研究语义熵、语义失真和语义通信速率等信息论指标,以刻画语义通信中的信息流。随后,本文提供实施语义通信的指南,以同时确保理论可解释性和通信有效性。

英文摘要:

With the exponential surge in traffic data and the pressing need for ultra-low latency in emerging intelligence applications, it is envisioned that 6G networks will demand disruptive communication technologies to foster ubiquitous intelligence and succinctness within the human society. Semantic communication, a novel paradigm, holds the promise of significantly curtailing communication overhead and latency by transmitting only task-relevant information. Despite numerous efforts in both theoretical frameworks and practical implementations of semantic communications, a substantial theory-practice gap complicates the theoretical analysis and interpretation, particularly when employing black-box machine learning techniques. This article initially delves into information-theoretic metrics such as semantic entropy, semantic distortions, and semantic communication rate to characterize the information flow in semantic communications. Subsequently, it provides a guideline for implementing semantic communications to ensure both theoretical interpretability and communication effectiveness.
