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…
