A Late Multi-Modal Fusion Model for Detecting Hybrid Spam E-mail

no code implementations26 Oct 2022 Zhibo Zhang, Ernesto Damiani, Hussam Al Hamadi, Chan Yeob Yeun, Fatma Taher

In recent years, spammers are now trying to obfuscate their intents by introducing hybrid spam e-mail combining both image and text parts, which is more challenging to detect in comparison to e-mails containing text or image only.

Poisoning Attacks and Defenses on Artificial Intelligence: A Survey

no code implementations21 Feb 2022 Miguel A. Ramirez, Song-Kyoo Kim, Hussam Al Hamadi, Ernesto Damiani, Young-Ji Byon, Tae-Yeon Kim, Chung-Suk Cho, Chan Yeob Yeun

This survey is conducted with a main intention of highlighting the most relevant information related to security vulnerabilities in the context of machine learning (ML) classifiers; more specifically, directed towards training procedures against data poisoning attacks, representing a type of attack that consists of tampering the data samples fed to the model during the training phase, leading to a degradation in the models accuracy during the inference phase.
