f-发散的联合值域

Joint Range of f-divergences

Peter Harremoës, Igor Vajda

摘要:

我们提供了一个一般的方法来评估的联合范围的f-发散的两个不同的功能f。通过拓扑论证证明了一般分布的联合值域等于二元集合上分布的联合值域的凸包。联合值域技术在信息论和统计学中有着广泛的应用,它提供了不同f-散度之间的重要不等式。

英文摘要:

We provide a general method for evaluation of the joint range of f-divergences for two different functions f. Via topological arguments we prove that the joint range for general distributions equals the convex hull of the joint range achieved by the distributions on a two-element set. The joint range technique provides important inequalities between different f-divergences with various applications in information theory and statistics.
