Rejection Sampling is Optimal for Relative Entropy Coding

Spencer Hill, Fady Alajaji, Tamas Linder, Gergely Flamich · 2026

In relative entropy coding, a sender aims to design a stochastic code such that, on input $X \sim P_X$, the receiver can generate a sample $Y \sim P_{Y \mid X}$. It is a standard result that (1) this …
