One-Class Classification for Intrusion Detection on Vehicular Networks

no code implementations25 Sep 2023 Jake Guidry, Fahad Sohrab, Raju Gottumukkala, Satya Katragadda, Moncef Gabbouj

Research has been done on the efficacy of these methods, most notably One-Class Support Vector Machine and Support Vector Data Description, but many new extensions of these works have been proposed and have yet to be tested for injection attacks in vehicular networks.

Newton Method-based Subspace Support Vector Data Description

no code implementations25 Sep 2023 Fahad Sohrab, Firas Laakom, Moncef Gabbouj

The objective of S-SVDD is to map the original data to a subspace optimized for one-class classification, and the iterative optimization process of data mapping and description in S-SVDD relies on gradient descent.

Early Myocardial Infarction Detection with One-Class Classification over Multi-view Echocardiography

no code implementations14 Apr 2022 Aysen Degerli, Fahad Sohrab, Serkan Kiranyaz, Moncef Gabbouj

In this study, we propose a framework for early detection of MI over multi-view echocardiography that leverages one-class classification (OCC) techniques.

Boosting rare benthic macroinvertebrates taxa identification with one-class classification

no code implementations12 Feb 2020 Fahad Sohrab, Jenni Raitoharju

One-class classification models are traditionally trained with much fewer samples and they can provide a mechanism to indicate samples potentially belonging to the rare classes for human inspection.
