Polar codes for channel and source coding

SB Korada - 2009 - infoscience.epfl.ch
The two central topics of information theory are the compression and the transmission of
data. Shannon, in his seminal work, formalized both these problems and determined their …

Polar codes are optimal for lossy source coding

SB Korada, RL Urbanke - IEEE Transactions on Information …, 2010 - ieeexplore.ieee.org
We consider lossy source compression of a binary symmetric source using polar codes and
a low-complexity successive encoding algorithm. It was recently shown by Arikan that polar …

For many random constraint satisfaction problems, by now there exist asymptotically tight
estimates of the largest constraint density for which solutions exist. At the same time, for …

The algorithmic phase transition of random k-sat for low degree polynomials

G Bresler, B Huang - 2021 IEEE 62nd Annual Symposium on …, 2022 - ieeexplore.ieee.org
Let Φ be a uniformly random k-SAT formula with n variables and m clauses. We study the
algorithmic task of finding a satisfying assignment of Φ. It is known that satisfying …

Sampling from mean-field gibbs measures via diffusion processes

AE Alaoui, A Montanari, M Sellke - arxiv preprint arxiv:2310.08912, 2023 - arxiv.org
We consider Ising mixed $ p $-spin glasses at high-temperature and without external field,

Hard optimization problems have soft edges

R Marino, S Kirkpatrick - Scientific Reports, 2023 - nature.com
Abstract Finding a Maximum Clique is a classic property test from graph theory; find any one
of the largest complete subgraphs in an Erdös-Rényi G (N, p) random graph. We use …
