Algorithms for Threshold Group Testing
Amin Coja-Oghlan, Remco van der Hofstad, Lena Krieg +3
We study the Threshold Group Testing (TGT) problem without a gap in the noiseless, non-adaptive setting, where the goal is to exactly recover a sparse binary vector from pooled tes…
Noisy Linear Group Testing: Exact Thresholds and Efficient Algorithms
Lukas Hintze, Lena Krieg, Olga Scheftelowitsch +1
In group testing, the task is to identify defective items by testing groups of them together using as few tests as possible. We consider the setting where each item is defective wi…
Bad local minima exist in the stochastic block model
Amin Coja-Oghlan, Lena Krieg, Johannes Christian Lawnik +1
We study the disassortative stochastic block model with three communities, a well-studied model of graph partitioning and Bayesian inference for which detailed predictions based on…
Noisy group testing via spatial coupling
Amin Coja-Oghlan, Max Hahn-Klimroth, Lukas Hintze +4
We study the problem of identifying a small set , , of infected individuals within a large population of size by testing groups of individuals simultaneously.…
Inevitability of Polarization in Geometric Opinion Exchange
Abdou Majeed Alidou, Júlia Baligács, Max Hahn-Klimroth +3
Polarization and unexpected correlations between opinions on diverse topics (including in politics, culture and consumer choices) are an object of sustained attention. However, num…
