Sibson -Mutual Information and Its Variational Representations
Amedeo Roberto Esposito, Michael Gastpar, Ibrahim Issa
Information measures can be constructed from Rényi divergences much like mutual information from Kullback-Leibler divergence. One such information measure is known as Sibson -mu…
Properties of the Strong Data Processing Constant for Rényi Divergence
Lifu Jin, Amedeo Roberto Esposito, Michael Gastpar
Strong data processing inequalities (SDPI) are an important object of study in Information Theory and have been well studied for -divergences. Universal upper and lower bounds h…
Tight Bounds for Linear and Non-Linear Contraction of Divergences via Duality
Amedeo Roberto Esposito, Marco Mondelli
We develop a novel framework for bounding the contraction of information divergences, using duality and associated norms in Orlicz spaces. By working in the dual space, we obtain a…
