Non-adaptive probabilistic group testing with noisy measurements: Near-optimal bounds with efficient algorithms

Chun Lam Chan, Pak Hou Che, Sidharth Jaggi, Venkatesh Saligrama

摘要:

我们考虑通过非自适应“随机池化”组测试从大集合中检测缺陷项的一小部分集的问题。我们考虑的情况下,当测量是无噪声的,和的情况下,当测量是嘈杂的(每个组测试的结果可能是独立的故障概率q)。这些方案的订单最优结果在文献中是已知的。我们给这些问题的查询复杂性的信息理论的下限,并提供相应的计算效率的算法,匹配的下限到一个常数因子。据我们所知,这项工作是第一次明确估计这样一个常数,这些问题的上限和下限之间的差距的特点。

英文摘要:

We consider the problem of detecting a small subset of defective items from a large set via non-adaptive "random pooling" group tests. We consider both the case when the measurements are noiseless, and the case when the measurements are noisy (the outcome of each group test may be independently faulty with probability q). Order-optimal results for these scenarios are known in the literature. We give information-theoretic lower bounds on the query complexity of these problems, and provide corresponding computationally efficient algorithms that match the lower bounds up to a constant factor. To the best of our knowledge this work is the first to explicitly estimate such a constant that characterizes the gap between the upper and lower bounds for these problems.
