对数凹下Rényi熵不等式的逆
Reversals of Rényi Entropy Inequalities under Log-Concavity
摘要:
我们建立了一个离散模拟的Rényi熵比较,由于Bobkov和Madiman。对于整数上的对数凹变量,最小熵在通常的香农熵的log e内。此外,我们还研究了Madiman和Kontoyannis研究的熵Rogers-Shephard不等式,并在连续和离散情形下对某些参数建立了一个尖锐的Rényi形式
英文摘要:
We establish a discrete analog of the Rényi entropy comparison due to Bobkov and Madiman. For log-concave variables on the integers, the min entropy is within log e of the usual Shannon entropy. Additionally we investigate the entropic Rogers-Shephard inequality studied by Madiman and Kontoyannis, and establish a sharp Rényi version for certain parameters in both the continuous and discrete cases
