Employing Deep Ensemble Learning for Improving the Security of Computer Networks against Adversarial Attacks

no code implementations25 Sep 2022 Ehsan Nowroozi, Mohammadreza Mohammadi, Erkay Savas, Mauro Conti, Yassine Mekdad

In this study, we present a novel architecture based on an ensemble classifier that combines the enhanced security of 1-Class classification (known as 1C) with the high performance of conventional 2-Class classification (known as 2C) in the absence of attacks. Our architecture is referred to as the 1. 5-Class (SPRITZ-1. 5C) classifier and constructed using a final dense classifier, one 2C classifier (i. e., CNNs), and two parallel 1C classifiers (i. e., auto-encoders).
