Abstract In this paper, we present a new refinement of Jensen’s inequality with applications in information theory. The refinement of Jensen’s inequality is obtained based on the general functional in the work of Popescu et al. As the applications in information theory, we provide new tighter bounds for Shannon’s entropy and some f-divergences.

Jensen 不等式的新改进在信息论中的应用

摘要 在本文中,我们提出了 Jensen 不等式在信息论中的应用的新改进。Jensen 不等式的细化是基于 Popescu 等人工作中的一般泛函获得的。作为在信息论中的应用,我们为香农熵和一些 f 散度提供了新的更严格的界限。
