Reconstructing signed relations from interaction data

no code implementations7 Sep 2022 Georges Andres, Giona Casiraghi, Giacomo Vaccario, Frank Schweitzer

We evaluate the importance of triads in the signed network to study group cohesion.

Should the government reward cooperation? Insights from an agent-based model of wealth redistribution

no code implementations14 Jan 2021 Frank Schweitzer, Luca Verginer, Giacomo Vaccario

The resulting budget is spent to cover administrative costs and to pay a bonus to cooperative agents, which can be identified correctly only with a probability $p$.

Quantifying the importance of firms by means of reputation and network control

no code implementations13 Jan 2021 Yan Zhang, Frank Schweitzer

The reputation of firms is largely channeled through their ownership structure.

Predicting Sequences of Traversed Nodes in Graphs using Network Models with Multiple Higher Orders

no code implementations13 Jul 2020 Christoph Gote, Giona Casiraghi, Frank Schweitzer, Ingo Scholtes

We propose a novel sequence prediction method for sequential data capturing node traversals in graphs.

Detecting Path Anomalies in Time Series Data on Networks

1 code implementation25 May 2019 Timothy LaRock, Vahan Nanumyan, Ingo Scholtes, Giona Casiraghi, Tina Eliassi-Rad, Frank Schweitzer

Anomaly detection has been extensively studied in categorical sequences, however we often have access to time series data that contain paths through networks.

Quantifying Triadic Closure in Multi-Edge Social Networks

1 code implementation8 May 2019 Laurence Brandenberger, Giona Casiraghi, Vahan Nanumyan, Frank Schweitzer

Standard approaches to measure this triadic closure, however, fail for multi-edge networks, because they do not consider that triads can be formed by edges of different multiplicity.

git2net - Mining Time-Stamped Co-Editing Networks from Large git Repositories

1 code implementation25 Mar 2019 Christoph Gote, Ingo Scholtes, Frank Schweitzer

Data from software repositories have become an important foundation for the empirical study of software engineering processes.

From Relational Data to Graphs: Inferring Significant Links using Generalized Hypergeometric Ensembles

1 code implementation14 Jun 2017 Giona Casiraghi, Vahan Nanumyan, Ingo Scholtes, Frank Schweitzer

We show how this framework can be used to assess the significance of links in noisy relational data.

Generalized Hypergeometric Ensembles: Statistical Hypothesis Testing in Complex Networks

1 code implementation8 Jul 2016 Giona Casiraghi, Vahan Nanumyan, Ingo Scholtes, Frank Schweitzer

Studying empirical and synthetic data, we show that our approach provides broad perspectives for model selection and statistical hypothesis testing in data on complex networks.
