Approximate Message Passing (AMP): An iterative algorithm inspired by statistical physics, designed to recover signals in high dimensions with performance characterised by a state evolution framework.

Within information theory, they are known as "approximate message passing" algorithms. We study the high-dimensional (large N) behavior of the iterates of F for polynomial functions F, and prove that ...
