Reed-Muller codes are among the oldest and best studied families of codes. They have many beautiful and useful properties. Recently they have drawn renewed interest due to their close relationship with Polar codes. This begs the question: Do they achieve capacity?
We discuss two problems related to the general challenge of making accurate inferences about a complex distribution, in the regime in which the amount of data (i.e the sample size) is too small for the empirical distribution of the samples to be an accurate representation of the underlying distri

Characterizing the computational complexity of statistical inference problems is an outstanding open problem.
In many real-world statistical problems, we observe a large number of potentially explanatory variables of which a majority may be irrelevant. For this type of problem, controlling the false discovery rate (FDR) guarantees that most of the discoveries are truly explanatory and thus replicable.
The cut-set bound developed by (Cover and El Gamal, 1979) has since remained the best known upper bound on the capacity of the Gaussian relay channel. We develop a new upper bound on the capacity of the Gaussian primitive relay channel which is tighter than the cut-set bound.
A class of diamond networks is studied where the broadcast component is orthogonal and modeled by two independent bit-pipes. New upper and lower bounds on the capacity are derived.
