Spectra of Modular Random Graphs
G. Ergun, R. Kuehn
We compute spectra of symmetric random matrices defined on graphs exhibiting a modular structure. Modules are initially introduced as fully connected sub-units of a graph. By contr…
Cavity Approach to the Spectral Density of Sparse Symmetric Random Matrices
Tim Rogers, Koujin Takeda, Isaac Pérez Castillo +1
The spectral density of various ensembles of sparse symmetric random matrices is analyzed using the cavity method. We consider two cases: matrices whose associated graphs are local…
Phase Transitions in Operational Risk
Kartik Anand, Reimer Kühn
In this paper we explore the functional correlation approach to operational risk. We consider networks with heterogeneous a-priori conditional and unconditional failure probability…
Learning with incomplete information - and the mathematical structure behind it
Reimer Kuehn, Ion-Olimpiu Stamatescu
Learning and the ability to learn are important factors in development and evolutionary processes [1]. Depending on the level, the complexity of learning can strongly vary. While a…
