Mutual Information Bounds for Lossy Common Information

Information Theory 2025-12-04 v4 Signal Processing math.IT

Abstract

We show the mutual information between the targets in a Gray-Wyner Network as a bound that separates Wyner's lossy common information and G\'acs-K\"orner lossy common information. The results are a generalization of the lossless case presented by Wyner (1975).
