Introducing multilayer stream graphs and layer centralities
Pimprenelle Parmentier, Tiphaine Viard, Benjamin Renoust +1
Graphs are commonly used in mathematics to represent some relationships between items. However, as simple objects, they sometimes fail to capture all relevant aspects of real-world…
Degree-based Outlier Detection within IP Traffic Modelled as a Link Stream
Audrey Wilmet, Tiphaine Viard, Matthieu Latapy +1
This paper aims at precisely detecting and identifying anomalous events in IP traffic. To this end, we adopt the link stream formalism which properly captures temporal and structur…
Weighted, Bipartite, or Directed Stream Graphs for the Modeling of Temporal Networks
Matthieu Latapy, Clémence Magnien, Tiphaine Viard
We recently introduced a formalism for the modeling of temporal networks, that we call stream graphs. It emphasizes the streaming nature of data and allows rigorous definitions of…
Movie rating prediction using content-based and link stream features
Tiphaine Viard, Raphaël Fournier-S'niehotta
While graph-based collaborative filtering recommender systems have been introduced several years ago, there are still several shortcomings to deal with, the temporal information be…
Stream Graphs and Link Streams for the Modeling of Interactions over Time
Matthieu Latapy, Tiphaine Viard, Clémence Magnien
Graph theory provides a language for studying the structure of relations, and it is often used to study interactions over time too. However, it poorly captures the both temporal an…
Analysis of the temporal and structural features of threads in a mailing-list
Noé Gaumont, Tiphaine Viard, Raphaël Fournier-S'niehotta +2
A link stream is a collection of triplets indicating that an interaction occurred between and at time . Link streams model many real-world situations like emai…
