使用反向Young不等式的尖锐版本,以及Fradelizi,Madiman和Wang(2016)的Rényi熵比较结果,当Rényi参数属于[0,1]时,作者推导出对数凹随机向量的Rényi熵幂不等式。此外,估计被证明是尖锐的绝对常数。
Using a sharp version of the reverse Young inequality, and a Rényi entropy comparison result due to Fradelizi, Madiman, and Wang (2016), the authors derive Rényi entropy power inequalities for log-concave random vectors when Rényi parameters belong to [0, 1]. Furthermore, the estimates are shown to be sharp up to absolute constants.
