Broadcasting on trees near criticality
Yuzhou Gu, Hajir Roozbehani, Yury Polyanskiy
We revisit the problem of broadcasting on -ary trees: starting from a Bernoulli random variable at a root vertex, each vertex forwards its value across binary symme…
Low density majority codes and the problem of graceful degradation
Hajir Roozbehani, Yury Polyanskiy
We study a problem of constructing codes that transform a channel with high bit error rate (BER) into one with low BER (at the expense of rate). Our focus is on obtaining codes wit…

Algebraic Methods of Classifying Directed Graphical Models
Hajir Roozbehani, Yury Polyanskiy
Directed acyclic graphical models (DAGs) are often used to describe common structural properties in a family of probability distributions. This paper addresses the question of clas…
