Ribbons from Independence Structure: Hypercontractivity, $Φ$ -Mutual Information, and Matrix $Φ$ -Entropy

Chenyu Wang, Amin Gohari

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

On Dependence Measures Based on $f$ -Divergence and $Φ$ -Entropy

Chenyu Wang, Amin Gohari

We study dependence measures induced by $Φ$ -divergence (also known as $f$ -divergence in the literature) for finite random variables. We define conditional $Φ$ -mutual information t…
