Radial Autoencoders for Enhanced Anomaly Detection
Mihai-Cezar Augustin, Vivien Bonvin, Regis Houssou +2
In classification problems, supervised machine-learning methods outperform traditional algorithms, thanks to the ability of neural networks to learn complex patterns. However, in t…
Generation and Simulation of Synthetic Datasets with Copulas
Regis Houssou, Mihai-Cezar Augustin, Efstratios Rappos +2
This paper proposes a new method to generate synthetic data sets based on copula models. Our goal is to produce surrogate data resembling real data in terms of marginal and joint d…
A Force-Directed Approach for Offline GPS Trajectory Map Matching
Efstratios Rappos, Stephan Robert, Philippe Cudré-Mauroux
We present a novel algorithm to match GPS trajectories onto maps offline (in batch mode) using techniques borrowed from the field of force-directed graph drawing. We consider a sim…
Treatment of Unicode canoncal decomposition among operating systems
Efstratios Rappos
This article shows how the text characters that have multiple representations under the Unicode standard are treated by popular operating systems. Whilst most characters have a uni…
