FADER: Fast Adversarial Example Rejection

no code implementations18 Oct 2020 Francesco Crecchi, Marco Melis, Angelo Sotgiu, Davide Bacciu, Battista Biggio

As a second main contribution of this work, we introduce FADER, a novel technique for speeding up detection-based methods.

Adversarial Robustness

Domain Knowledge Alleviates Adversarial Attacks in Multi-Label Classifiers

no code implementations6 Jun 2020 Stefano Melacci, Gabriele Ciravegna, Angelo Sotgiu, Ambra Demontis, Battista Biggio, Marco Gori, Fabio Roli

Adversarial attacks on machine learning-based classifiers, along with defense mechanisms, have been widely studied in the context of single-label classification problems.

Multi-Label Classification

Deep Neural Rejection against Adversarial Examples

1 code implementation1 Oct 2019 Angelo Sotgiu, Ambra Demontis, Marco Melis, Battista Biggio, Giorgio Fumera, Xiaoyi Feng, Fabio Roli

Despite the impressive performances reported by deep neural networks in different application domains, they remain largely vulnerable to adversarial examples, i. e., input samples that are carefully perturbed to cause misclassification at test time.

IntelliAV: Building an Effective On-Device Android Malware Detector

no code implementations4 Feb 2018 Mansour Ahmadi, Angelo Sotgiu, Giorgio Giacinto

Several anti-malware vendors have claimed and advertised the application of machine learning in their products in which the inference phase is performed on servers and high-performance machines, but the feasibility of such approaches on mobile devices with limited computational resources has not yet been assessed by the research community, vendors still being skeptical.
