Abstract:
Random sparse graphical models appear in a variety of contexts,
ranging from communications to combinatorics and statistical
mechanics. An increasingly sophisticated theory has been
developed to analyze message passing algorithms (such as belief
propagation) in such problems.
This analysis plays a double role: (i) It opens the way to the
design/optimization of these systems; (i) It provides a new array
of proof techniques to deal with difficult mathematical problems.
I will review these developments working out one particular example:
belief propagation-based multi-user detection.
