Efficient Computation of Marton's Error Exponent via Constraint Decoupling

Jiachuan Ye, Shitong Wu, Lingyi Chen +3

The error exponent in lossy source coding characterizes the asymptotic decay rate of error probability with respect to blocklength. The Marton's error exponent provides the theoret…

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…
