Ising Model on Locally Tree-like Graphs: Uniqueness of Solutions to Cavity Equations
Qian Yu, Yury Polyanskiy
In the study of Ising models on large locally tree-like graphs, in both rigorous and non-rigorous methods one is often led to understanding the so-called belief propagation distrib…
Likelihood-free hypothesis testing
Patrik Róbert Gerber, Yury Polyanskiy
Consider the problem of binary hypothesis testing. Given coming from either or , to decide between the two with small probability…
Finite-Blocklength Results for the A-channel: Applications to Unsourced Random Access and Group Testing
Alejandro Lancho, Alexander Fengler, Yury Polyanskiy
We present finite-blocklength achievability bounds for the unsourced A-channel. In this multiple-access channel, users noiselessly transmit codewords picked from a common codebook…
Data-Driven Blind Synchronization and Interference Rejection for Digital Communication Signals
Alejandro Lancho, Amir Weiss, Gary C. F. Lee +4
We study the potential of data-driven deep learning methods for separation of two communication signals from an observation of their mixture. In particular, we assume knowledge on…
Optimal empirical Bayes estimation for the Poisson model via minimum-distance methods
Soham Jana, Yury Polyanskiy, Yihong Wu
The Robbins estimator is the most iconic and widely used procedure in the empirical Bayes literature for the Poisson model. On one hand, this method has been recently shown to be m…
Exploiting Temporal Structures of Cyclostationary Signals for Data-Driven Single-Channel Source Separation
Gary C. F. Lee, Amir Weiss, Alejandro Lancho +4
We study the problem of single-channel source separation (SCSS), and focus on cyclostationary signals, which are particularly suitable in a variety of application domains. Unlike c…
