A Lattice of Gambles

Paul Cuff, Thomas Cover, Gowtham Kumar +1

A gambler walks into a hypothetical fair casino with a very real dollar bill, but by the time he leaves he's exchanged the dollar for a random amount of money. What is lost in the…

Compression with Actions

Lei Zhao, Yeow-Khiang Chia, Tsachy Weissman

We consider the setting where actions can be used to modify a state sequence before compression. The minimum rate needed to losslessly describe the optimal modified sequence is cha…

Universal Estimation of Directed Information

Jiantao Jiao, Haim H. Permuter, Lei Zhao +2

Four estimators of the directed information rate between a pair of jointly stationary ergodic finite-alphabet processes are proposed, based on universal probability assignments. Th…

Coordination using Implicit Communication

Paul Cuff, Lei Zhao

We explore a basic noise-free signaling scenario where coordination and communication are naturally merged. A random signal X_1,...,X_n is processed to produce a control signal or…

A Random Variable Substitution Lemma With Applications to Multiple Description Coding

Jia Wang, Jun Chen, Lei Zhao +2

We establish a random variable substitution lemma and use it to investigate the role of refinement layer in multiple description coding, which clarifies the relationship among seve…

Zero-error feedback capacity via dynamic programming

Lei Zhao, Haim Permuter

In this paper, we study the zero-error capacity for finite state channels with feedback when channel state information is known to both the transmitter and the receiver. We prove t…
