Multivariate Mutual Information Inspired by Secret-Key Agreement
Proceedings of the IEEE, Volume 103, Issue 10, 2015, Pages 1883-1913.
The capacity for multiterminal secret-key agreement inspires a natural generalization of Shannon's mutual information from two random variables to multiple random variables. Under a general source model without helpers, the capacity is shown to be equal to the normalized divergence from the joint distribution of the random sources to the ...More
