Intrinsic entropies of log-concave distributions
Varun Jog, Venkat Anantharam
The entropy of a random variable is well-known to equal the exponential growth rate of the volumes of its typical sets. In this paper, we show that for any log-concave random varia…

A Variational Characterization of Rényi Divergences
Venkat Anantharam
Atar, Chowdhary and Dupuis have recently exhibited a variational formula for exponential integrals of bounded measurable functions in terms of Rényi divergences. We develop a varia…
