Spectral clustering of time-evolving networks using spatio-temporal random walks

Filip Blašković, Tim O. F. Conrad, Stefan Klus +1

Temporal (or time-evolving) networks provide a natural framework for modeling complex systems with time-dependent interactions, where understanding the evolution of community struc…

Data-driven approximation of Koopman operators and generators: Convergence rates and error bounds

Liam Llamazares-Elias, Samir Llamazares-Elias, Jonas Latz +1

Global information about dynamical systems can be extracted by analysing associated infinite-dimensional transfer operators, such as Perron--Frobenius and Koopman operators as well…

Random walk based snapshot clustering for detecting community dynamics in temporal networks

Filip Blašković, Tim O. F. Conrad, Stefan Klus +1

The evolution of many dynamical systems that describe relationships or interactions between objects can be effectively modeled by temporal networks, which are typically represented…

Clustering Time-Evolving Networks Using the Spatio-Temporal Graph Laplacian

Maia Trower, Nataša Djurdjevac Conrad, Stefan Klus

Time-evolving graphs arise frequently when modeling complex dynamical systems such as social networks, traffic flow, and biological processes. Developing techniques to identify and…

Dynamical systems and complex networks: A Koopman operator perspective

Stefan Klus, Nataša Djurdjevac Conrad

The Koopman operator has entered and transformed many research areas over the last years. Although the underlying concept$\unicode{x2013}$representing highly nonlinear dynamical sy…
