高稀释度方案中的分组检测

Group Testing in the High Dilution Regime

Gabriel Arpino, Nicolò Grometto, Afonso S. Bandeira

摘要:

非适应性分组测试是指使用最少数量的同时合并测试从较大的总体中推断稀疏的缺陷集的问题。最近的积极成果,无噪声组测试激励研究的实际噪声模型,一个突出的是稀释噪声。在稀释噪声模型下,测试池中的项目具有i.i.d.被稀释的概率,意味着它们对测试的贡献不起作用。在这种情况下,我们调查的数量,以实现消失的错误概率与现有的算法,并提供了一个算法独立的逆界所需的测试。与其他噪声模型相比,我们还遇到了有趣的现象,即稀释噪声对测试结果可以通过选择一个合适的噪声水平相关的伯努利测试设计来抵消,从而在匹配的可扩展性和逆边界的顺序在高噪声制度。

英文摘要:

Non-adaptive group testing refers to the problem of inferring a sparse set of defectives from a larger population using the minimum number of simultaneous pooled tests. Recent positive results for noiseless group testing have motivated the study of practical noise models, a prominent one being dilution noise. Under the dilution noise model, items in a test pool have an i.i.d. probability of being diluted, meaning their contribution to a test does not take effect. In this setting, we investigate the number of tests required to achieve vanishing error probability with respect to existing algorithms and provide an algorithm-independent converse bound. In contrast to other noise models, we also encounter the interesting phenomenon that dilution noise on the resulting test outcomes can be offset by choosing a suitable noise-level-dependent Bernoulli test design, resulting in matching achievability and converse bounds up to order in the high noise regime.
