Persistence of centrality in random growing trees
Varun Jog, Po-Ling Loh
We investigate properties of node centrality in random growing tree models. We focus on a measure of centrality that computes the maximum subtree size of the tree rooted at each no…
Information-theoretic bounds for exact recovery in weighted stochastic block models using the Renyi divergence
Varun Jog, Po-Ling Loh
We derive sharp thresholds for exact recovery of communities in a weighted stochastic block model, where observations are collected in the form of a weighted adjacency matrix, and…
A Geometric Analysis of the AWGN channel with a -Power Constraint
Varun Jog, Venkat Anantharam
In this paper, we consider the AWGN channel with a power constraint called the -power constraint, which is motivated by energy harvesting communication systems. Given a cod…
On model misspecification and KL separation for Gaussian graphical models
Varun Jog, Po-Ling Loh
We establish bounds on the KL divergence between two multivariate Gaussian distributions in terms of the Hamming distance between the edge sets of the corresponding graphical model…
