    Internet traffic classification using SVM with flexible feature space by Yaguan QIAN, Xiaohui GUAN, Bensheng YUN, Qiong LOU, Pengfei MA

    Published 2016-05-01
    “…SVM is a typical machine learning algorithm with prefect generalization capacity,which is suitable for the internet traffic classification.At present,there are two approaches,One-Against-All and One-Against-One,proposed for extending SVM to multi-class problem like traffic classification.However,these approaches are both based on a unique feature space.In fact,the separating capacity of a special traffic feature is not similar to different applications.Hence,flexible feature space for extending SVM was proposed,which constructs independent feature space with optimal discriminability for each binary-SVM and trains them under their own feature space.Finally,these trained binary-SVM were ensemble by One-Against-All and One-Against-One approaches.The experiments show that the proposed approach can efficiently improve the precision and callback of the traffic classifier and easily obtain more reasonable optimal separating hyper-plane.…”

    Published 2016-08-01
    “…A modified SVM multi-classification algorithm integrated with discriminant analysis (D-SVM) was pro-posed,which could solve the problem of low detection accuracy and high false alarm rate caused by unbalanced datasets.For a multi-classification problem could be divided into several binary classification problems,D-SVM could not only have the virtue of high detection accuracy,but also have a low false alarm rate even confronted with unbalanced datasets.Experiments based on KDD99 dataset verify the feasibility and validity of the integrated ap-proach.Results show that when confronted with multi-classification problems,D-SVM could achieve a high detec-tion accuracy and low false alarm rate even when SVM alone fails because of the unbalanced datasets.…”

    Performance enhancement scheme for IRS-assisted cognitive backscatter communication network by Bin LYU, Yi CAO, Jian LI, Ting QI

    Published 2021-12-01
    “…In order to achieve the self-sustainable cognitive radio network (CRN) and improve its communication efficiency, an efficient multi-mode switching scheme assisted by the intelligent reflecting surface (IRS) for the overlay scenario was proposed.In particular, the secondary transmitter (ST) could work in either backscatter communication (BackCom) mode or harvest-then-transmit (HTT) mode.The IRS was exploited to enhance the energy harvesting, information backscattering, and information transmission efficiencies at the ST.To maximize the system sum-rate, an optimization problem about the phase shirts at the IRS, time scheduling, and power allocation was formulated.Since the formulated problem was non-convex, an efficient block coordinate descent (BCD) based algorithm was proposed to achieve the sub-optimal solution.Simulation results confirm that the proposed scheme can achieve up to 200% sum-rate gain over the benchmark schemes.…”
