Anomaly detection in the dynamics of web and social networks
Volodymyr Miz, Benjamin Ricaud, Kirell Benzi +1
In this work, we propose a new, fast and scalable method for anomaly detection in large time-evolving graphs. It may be a static graph with dynamic node attributes (e.g. time-serie…
Optimal Window and Lattice in Gabor Transform Application to Audio Analysis
Helene Lachambre, Benjamin Ricaud, Guillaume Stempfel +3
This article deals with the use of optimal lattice and optimal window in Discrete Gabor Transform computation. In the case of a generalized Gaussian window, extending earlier contr…
Analysis and separation of time-frequency components in signals with chaotic behavior
Benjamin Ricaud, Francoise Briolle, F. Clairet
The analysis of chaotic signals with time-frequency methods is considered. For this purpose, two new transformations are presented which consist in the decomposition of a signal on…
