Inference and mutual information on random factor graphs

Amin Coja-Oghlan, Max Hahn-Klimroth, Philipp Loick +3

Random factor graphs provide a powerful framework for the study of inference problems such as decoding problems or the stochastic block model. Information-theoretically the key qua…

Optimal group testing

Amin Coja-Oghlan, Oliver Gebhard, Max Hahn-Klimroth +1

In the group testing problem the aim is to identify a small set of infected individuals out of a population size , . We avail ourselves of a test procedure ca…

Information-theoretic and algorithmic thresholds for group testing

Amin Coja-Oghlan, Oliver Gebhard, Max Hahn-Klimroth +1

In the group testing problem we aim to identify a small number of infected individuals within a large population. We avail ourselves to a procedure that can test a group of multipl…

Charting the replica symmetric phase

Amin Coja-Oghlan, Charilaos Efthymiou, Nor Jaafari +2

Diluted mean-field models are spin systems whose geometry of interactions is induced by a sparse random graph or hypergraph. Such models play an eminent role in the statistical mec…

Information-theoretic thresholds from the cavity method

Amin Coja-Oghlan, Florent Krzakala, Will Perkins +1

Vindicating a sophisticated but non-rigorous physics approach called the cavity method, we establish a formula for the mutual information in statistical inference problems induced…

Hypergraph coloring up to condensation

Peter Ayre, Amin Coja-Oghlan, Catherine Greenhill

Improving a result of Dyer, Frieze and Greenhill [Journal of Combinatorial Theory, Series B, 2015], we determine the -colorability threshold in random -uniform hypergraphs up…
