Discrete Layered Entropy, Conditional Compression and a Tighter Strong Functional Representation Lemma
Cheuk Ting Li
We study a quantity called discrete layered entropy, which approximates the Shannon entropy within a logarithmic gap. Compared to the Shannon entropy, the discrete layered entropy…

Rejection-Sampled Linear Codes for Lossy Compression and Channel Simulation
Jianguo Zhao, Cheuk Ting Li
We show that linear codes combined with rejection sampling can yield a capacity-achieving scheme for simulating additive exchangeable noise channels. Specifically, our scheme achie…
