Discovering Patterns in Time-Varying Graphs: A Triclustering Approach
Romain Guigourès, Marc Boullé, Fabrice Rossi
This paper introduces a novel technique to track structures in time varying graphs. The method uses a maximum a posteriori approach for adjusting a three-dimensional co-clustering…
Co-Clustering Network-Constrained Trajectory Data
Mohamed Khalil El Mahrsi, Romain Guigourès, Fabrice Rossi +1
Recently, clustering moving object trajectories kept gaining interest from both the data mining and machine learning communities. This problem, however, was studied mainly and exte…
A Study of the Spatio-Temporal Correlations in Mobile Calls Networks
Romain Guigourès, Marc Boullé, Fabrice Rossi
For the last few years, the amount of data has significantly increased in the companies. It is the reason why data analysis methods have to evolve to meet new demands. In this arti…
Nonparametric Hierarchical Clustering of Functional Data
Marc Boullé, Romain Guigourès, Fabrice Rossi
In this paper, we deal with the problem of curves clustering. We propose a nonparametric method which partitions the curves into clusters and discretizes the dimensions of the curv…
