In this paper, a boosting-based incremental hybrid intrusion detection system is introduced. This system combines incremental misuse detection and incremental anomaly detection. We use boosting ensemble of weak classifiers to implement misuse intrusion detection system. It can identify new classes types of intrusions that do not exist in the training dataset for incremental misuse detection. As...

In this paper, we presents a stance detection system for NLPCC-ICCPOL 2016 share task 4. Our Stance Detection System can determinate whether the author of Weibo text is in favor of the given target, against the given target, or neither. We exploit LSTMs model and the average F score of our system is 56.56%. In contrast to the traditional target/aspect sentiment, the given target may not be pres...

the purpose of this study is the fusion of polarimetric sar and hyperspectral images for concealed target detection in forest areas. the proposed method is using the polarimetric and the spectral signatures. a radarsat-2 image and a hyperion image of the city san francisco were chosen for evaluation of the proposed method. the four targets were selected in the forest and the outer areas. three ...

Increasing the popularity of SIP based services (VoIP, IPTV, IMS infrastructure) lead to concerns about its ‎security. The main signaling protocol of next generation networks and VoIP systems is Session Initiation Protocol ‎‎(SIP). Inherent vulnerabilities of SIP, misconfiguration of its related components and also its implementation ‎deficiencies cause some security concerns in SIP based infra...

in this paper, the potential of polarimetric sar data using target decomposition features to detect oil pollutions are evaluated. for this purpose, the values of power, phase and magnitude of all of the polarization channels (hh, vv, hv and vh) and decomposition features i.e. freeman, yamaguchi, vanzyl and krogager are computed. then, to detect oil pollutions, different combinations of these fe...

A combined algorithm for automatic target detection and height estimation, based on amplitude comparison using multipath lobes of three sensors positioned one above the other, and a three-positioned in a plane method, is proposed in this paper. A method for three-positioned radar system base estimation, allowing target height measurement with height probability of detection, is developed and ap...
