Empirical coordination in the finite blocklength regime: an achievability result---Extended version
Olivier Massicot, Giulia Cervia, Maël Le Treust
Empirical coordination offers a way to understand how agents can coordinate actions under communication constraints. This paper investigates the finite blocklength regime of this p…
Empirical Coordination over Markov Channel with Independent Source
Mengyuan Zhao, Maël Le Treust, Tobias J. Oechtering
We study joint source-channel coding over Markov channels through the empirical coordination framework. More specifically, we aim at determining the empirical distributions of sour…
Causal Coordination for Distributed Decision-Making
Mengyuan Zhao, Tobias J. Oechtering, Maël Le Treust
In decentralized network control, communication plays a critical role by transforming local observations into shared knowledge, enabling agents to coordinate their actions. This pa…
Zero Estimation Cost Strategy for Witsenhausen Counterexample with Causal Encoder
Mengyuan Zhao, Tobias J. Oechtering, Maël Le Treust
We propose a zero estimation cost (ZEC) scheme for causal-encoding noncausal-decoding vector-valued Witsenhausen counterexample based on the coordination coding result. In contrast…
Single-Letter Characterization of the Mismatched Distortion-Rate Function
Maël Le Treust, Tristan Tomala
The mismatched distortion-rate problem has remained open since its formulation by Lapidoth in 1997. In this paper, we characterize the mismatched distortion-rate function. Our sing…
Causal Vector-valued Witsenhausen Counterexamples with Feedback
Mengyuan Zhao, Maël Le Treust, Tobias J. Oechtering
We study the continuous vector-valued Witsenhausen counterexample through the lens of empirical coordination coding. We characterize the region of achievable pairs of costs in thre…
