有效地测试分布标识

Testing Distribution Identity Efficiently

Krzysztof Onak

摘要:

我们考虑分布恒等式的检验问题。给定来自大小为n的域上的未知分布的独立样本序列,目标是检查未知分布是否近似等于相同域上的已知分布。Batu,Fortnow,Fischer,Kumar,Rubinfeld,and White(FOCS 2001)证明了该问题的样本复杂度为O~(sqrt(n)* poly(1/n)),而他们的测试程序的运行时间要高得多:O(n)+ O~(sqrt(n)* poly(1/n))。我们修改了他们的测试器,使其运行时间为O~(sqrt(n)* poly(1/n))。

英文摘要:

We consider the problem of testing distribution identity. Given a sequence of independent samples from an unknown distribution on a domain of size n, the goal is to check if the unknown distribution approximately equals a known distribution on the same domain. While Batu, Fortnow, Fischer, Kumar, Rubinfeld, and White (FOCS 2001) proved that the sample complexity of the problem is O~(sqrt(n) * poly(1/epsilon)), the running time of their tester is much higher: O(n) + O~(sqrt(n) * poly(1/epsilon)). We modify their tester to achieve a running time of O~(sqrt(n) * poly(1/epsilon)).
