不同适应性群体测验的容量

The capacity of non-identical adaptive group testing

Tom Kealy, Oliver Johnson, Robert Piechocki

摘要:

我们考虑的情况下,项目是独立的,但有非常数的概率有缺陷的成组测试问题。我们介绍并分析了一种算法来解决这个问题,通过适当地将项目分组在一起。我们给出的条件下,该算法执行基本上是最佳的意义上的信息理论的能力。我们使用测量结果的集中度来限制该算法需要比预期数量更多的测试的概率。在数据库给出特定频带将被占用的先验信息的情况下,这对认知无线电的频谱分配具有应用。

英文摘要:

We consider the group testing problem, in the case where the items are defective independently but with non-constant probability. We introduce and analyse an algorithm to solve this problem by grouping items together appropriately. We give conditions under which the algorithm performs essentially optimally in the sense of information-theoretic capacity. We use concentration of measure results to bound the probability that this algorithm requires many more tests than the expected number. This has applications to the allocation of spectrum to cognitive radios, in the case where a database gives prior information that a particular band will be occupied.
