RDD Function: A Tradeoff Between Rate and Distortion-in-Distortion
Lingyi Chen, Haoran Tang, Shitong Wu +4
In this paper, we propose a novel function named Rate Distortion-in-Distortion (RDD) function as an extension of the classical rate-distortion (RD) function, where the expected dis…
A Rate-Distortion Analysis for Composite Sources Under Subsource-Dependent Fidelity Criteria
Jiakun Liu, H. Vincent Poor, Iickho Song +1
A composite source, consisting of multiple subsources and a memoryless switch, outputs one symbol at a time from the subsource selected by the switch. If some data should be encode…
PAC Learnability for Reliable Communication over Discrete Memoryless Channels
Jiakun Liu, Wenyi Zhang, H. Vincent Poor
In practical communication systems, knowledge of channel models is often absent, and consequently, transceivers need be designed based on empirical data. In this work, we study dat…
An Indirect Rate-Distortion Characterization for Semantic Sources: General Model and the Case of Gaussian Observation
Jiakun Liu, Shuo Shao, Wenyi Zhang +1
A new source model, which consists of an intrinsic state part and an extrinsic observation part, is proposed and its information-theoretic characterization, namely its rate-distort…
A Rate-Distortion Framework for Characterizing Semantic Information
Jiakun Liu, Wenyi Zhang, H. Vincent Poor
A rate-distortion problem motivated by the consideration of semantic information is formulated and solved. The starting point is to model an information source as a pair consisting…
