Improving Network Anomaly Detection via Choquet-Integral-Based Feature Aggregation

Abreu Quevedo, Roger Immich, Giancarlo Lucca, Graçaliz Dimuro, Bruno L. Dalmazo

This work investigates a generalized Choquet-integral-based feature aggregation framework to improve anomaly detection in high-dimensional network traffic data. The approach combines adaptive weighting with incremental feature selection to address feature redundancy. Using Random…

On the Impact of Entropy-based Features

Iuri Mundstock, Abreu Quevedo, Jéferson Campos Nobre, Roben C. Lunardi, Thiago L. T. da Silveira, Bruno L. Dalmazo

Network anomaly detection is increasingly challenging due to the growing diversity and variability of traffic patterns, which are not always well captured by traditional statistical features. In this work, we explore the use of entropy as an additional feature to support supervis…
