Ribbons from Independence Structure: Hypercontractivity, $I^¦$ -Mutual Information, and Matrix $I^¦$ -Entropy

Chenyu Wang, Amin Gohari

We study the hypercontractivity ribbon and the $I^¦$ -ribbon for joint distributions that obey a given independence structure, obtaining tight bounds in some basic regimes. For gener…

On Phi-entropic Dependence Measures and Non-local Correlations

Chenyu Wang, Amin Gohari

We say that a measure of dependence between two random variables $X$ and $Y$ , denoted as $I ¨ (X; Y)$ , satisfies the data processing property if $I ¨ (X; Y) \geq I ¨ (X^{'}; Y^{'})$ for every $X'\…
