Deterministic sketching for Krylov subspace methods
Kai Bergermann
Randomized sketching is currently introduced into every area of numerical linear algebra. In Krylov subspace methods, it allows runtime savings at the cost of small accuracy reduct…

Gradient flow-based modularity maximization for community detection in multiplex networks
Kai Bergermann, Martin Stoll
We propose two methods for the unsupervised detection of communities in undirected multiplex networks. These networks consist of multiple layers that record different relationships…
