Detecting and Mitigating DDoS Attacks with AI: A Survey
Alexandru Apostu, Silviu Gheorghe, Andrei Hîji +5
Distributed Denial of Service attacks represent an active cybersecurity research problem. Recent research shifted from static rule-based defenses towards AI-based detection and mit…
Fusing Dictionary Learning and Support Vector Machines for Unsupervised Anomaly Detection
Paul Irofti, Iulian-Andrei Hîji, Andrei Pătraşcu +1
We study in this paper the improvement of one-class support vector machines (OC-SVM) through sparse representation techniques for unsupervised anomaly detection. As Dictionary Lear…
Optimized projections for compressed sensing via rank-constrained nearest correlation matrix
Nicolae Cleju
Optimizing the acquisition matrix is useful for compressed sensing of signals that are sparse in overcomplete dictionaries, because the acquisition matrix can be adapted to the par…
Analysis-based sparse reconstruction with synthesis-based solvers
Nicolae Cleju, Maria G. Jafari, Mark D. Plumbley
Analysis based reconstruction has recently been introduced as an alternative to the well-known synthesis sparsity model used in a variety of signal processing areas. In this paper…
Selection of network coding nodes for minimal playback delay in streaming overlays
Nicolae Cleju, Nikolaos Thomos, Pascal Frossard
Network coding permits to deploy distributed packet delivery algorithms that locally adapt to the network availability in media streaming applications. However, it may also increas…
