Entropies of sums of independent gamma random variables

Giorgos Chasapis, Salil Singh, Tomasz Tkocz

AI总结:

本文在固定方差下研究独立伽马随机变量加权和的Rényi熵,建立Schur-凸性结果并给出非渐近界,简化并扩展了已有结论。

摘要:

我们在固定方差下,针对独立伽马随机变量的加权和建立了若干Schur-凸性类型的结果,并获得了其Rényi熵的非渐近界。特别地,这涉及Bartczak-Nayar-Zwara以及Bobkov-Naumov-Ulyanov的最新结果,为前者提供了简单证明,并扩展了后者。

英文摘要:

We establish several Schur-convexity type results under fixed variance for weighted sums of independent gamma random variables and obtain nonasymptotic bounds on their Rényi entropies. In particular, this pertains to the recent results by Bartczak-Nayar-Zwara as well as Bobkov-Naumov-Ulyanov, offering simple proofs of the former and extending the latter.
