Shiryaev-Roberts过程的最优性

On Optimality Properties of the Shiryaev-Roberts Procedure

Moshe Pollak, Alexander G. Tartakovsky

摘要:

我们考虑简单的变点问题的设置,观察是独立的,iid前的变化和iid后的变化,与已知的前和后的变化分布。Shiryaev-Roberts检测过程是已知的渐近极小极大的意义上最小化最大预期检测延迟的平均运行长度上的一个绑定到虚警,因为后者走向无穷大。在这里,我们提出了Shiryaev-Roberts过程的其他最优性性质。

英文摘要:

We consider the simple changepoint problem setting, where observations are independent, iid pre-change and iid post-change, with known pre- and post-change distributions. The Shiryaev-Roberts detection procedure is known to be asymptotically minimax in the sense of minimizing maximal expected detection delay subject to a bound on the average run length to false alarm, as the latter goes to infinity. Here we present other optimality properties of the Shiryaev-Roberts procedure.
