Shannon Bounds for Quadratic Rate-Distortion Problems
Michael Gastpar, Erixhen Sula
The Shannon lower bound has been the subject of several important contributions by Berger. This paper surveys Shannon bounds on rate-distortion problems under mean-squared error di…
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…
Simultaneous Computation and Communication over MAC
Matthias Frey, Igor Bjelaković, Michael C. Gastpar +1
We study communication over a Gaussian multiple-access channel (MAC) with two types of transmitters: Digital transmitters hold a message from a discrete set that needs to be commun…
