Minimum--Entropy Couplings and their Applications

Ferdinando Cicalese, Luisa Gargano, Ugo Vaccaro

Given two discrete random variables $X$ and $Y,$ with probability distributions $p = (p_{1}, \dots, p_{n})$ and $q = (q_{1}, \dots, q_{m})$ , respectively, denote by ${\cal C}({…

Maximum Entropy Interval Aggregations

Ferdinando Cicalese, Ugo Vaccaro

Given a probability distribution $p = (p_{1}, \dots, p_{n})$ and an integer $1 \leq m < n$ , we say that $q = (q_{1}, \dots, q_{m})$ is a contiguous $m$ -aggregation of $p$ …

Bounds on the Entropy of a Function of a Random Variable and their Applications

Ferdinando Cicalese, Luisa Gargano, Ugo Vaccaro

It is well known that the entropy $H (X)$ of a discrete random variable $X$ is always greater than or equal to the entropy $H (f (X))$ of a function $f$ of $X$ , with equality if and o…
