Research ArticleOpen accessIn the abstractDesign and Bandwidth Analysis of Fault-Tolerant Multistage Interconnection NetworksR. Aggarwal, L. KaurThe design of a suitable interconnection network for inter-processor communication is one of the key issues of the system performance. In this study a new irregular interconnection network IABN (Irregular Augmented Baseline) has been proposed. IABN is designed by modifying existing ABN (Augmented Baseline Network). ABN is a regular multi-path network with limited fault tolerance. IABN provides three times more … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,835 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparison Study between Different Sampling Strategies for Intrusion Detection System of Active Learning ModelGhofran Mohammad Alqaralleh, Mohammad Aref Alshraideh, Ali AlrodanActive learning aims to train an accurate model with minimum cost by labeling the most informative instances without compromising the model performance. So, choosing an efficient criterion for instance selection is the most important step. Sampling stage is the main issue in active learning for many problems such as intrusion detection system.
