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…
On Semi-Supervised Estimation of Distributions
H. S. Melihcan Erol, Erixhen Sula, Lizhong Zheng
We study the problem of estimating the joint probability mass function (pmf) over two random variables. In particular, the estimation is based on the observation of samples con…
On the Semi-supervised Expectation Maximization
Erixhen Sula, Lizhong Zheng
The Expectation Maximization (EM) algorithm is widely used as an iterative modification to maximum likelihood estimation when the data is incomplete. We focus on a semi-supervised…
Shannon Bounds on Lossy Gray-Wyner Networks
Erixhen Sula, Michael Gastpar
The Gray-Wyner network subject to a fidelity criterion is studied. Upper and lower bounds for the trade-offs between the private sum-rate and the common rate are obtained for arbit…
Lower bound on Wyner's Common Information
Erixhen Sula, Michael Gastpar
An important notion of common information between two random variables is due to Wyner. In this paper, we derive a lower bound on Wyner's common information for continuous random v…
Common Information Components Analysis
Michael Gastpar, Erixhen Sula
We give an information-theoretic interpretation of Canonical Correlation Analysis (CCA) via (relaxed) Wyner's common information. CCA permits to extract from two high-dimensional d…
