论文摘要
简短说明的目的是讨论Kullback-Leibler Divergence与总变化距离之间的关系，从著名的Pinsker的不平等问题开始，然后再转变为简单，（可以说）更有用的不平等，显然是由于Bretagnolle和Huber而言，显然不是很有用的不平等。我们还讨论了该界限用于最小值测试下限的应用。
The goal of this short note is to discuss the relation between Kullback--Leibler divergence and total variation distance, starting with the celebrated Pinsker's inequality relating the two, before switching to a simple, yet (arguably) more useful inequality, apparently not as well known, due to Bretagnolle and Huber. We also discuss applications of this bound for minimax testing lower bounds.
