What are higher-order networks?

Understand

Network-based modeling of complex systems and data using the language of graphs has become an essential topic across a range of different disciplines.

• Arguably, this graph-based perspective derives its success from the relative simplicity of graphs: A graph consists of nothing more than a set of vertices and a set of edges, describing relationships between pairs of such vertices.
• This simple combinatorial structure makes graphs interpretable and flexible modeling tools.
• The simplicity of graphs as system models, however, has been scrutinized in the literature recently.
