INDEPENDENCE AND CONDITIONAL DECOMPOSABLE INFORMATION MEASURES

Open publisher page 0 citations

Abstract

We deal with conditional decomposable information measures, directly defined as functions on a suitable set of conditional events satisfying a class of axioms. For these general measures we introduce a notion of independence and study its main properties in order to compare it with classical definitions present in the literature. The particular case of Wiener-Shannon information measure is taken in consideration and the links between the provided independence for information measures and the independence for the underlying probability are analyzed.
