Dual total correlation
From Wikipedia, the free encyclopedia
In information theory, dual total correlation,[1] information rate,[2] excess entropy,[3][4] or binding information[5] is one of several known non-negative generalizations of mutual information. While total correlation is bounded by the sum entropies of the n elements, the dual total correlation is bounded by the joint-entropy of the n elements. Although well behaved, dual total correlation has received much less attention than the total correlation. A measure known as "TSE-complexity" defines a continuum between the total correlation and dual total correlation.[3]
