Imaging method based on compressed sensing for the cognitive sparse aperture of ISAR by Feng-lian SUN, Qun ZHANG, Ying LUO, Fu-fei GU, Guo-zheng WANG

“…Focused on the problem that different ISAR targets required different measurement dimension and different imaging time when they were imaging with compressed sensing(CS)theory,a cognitive high-resolution imaging method based on CS was proposed.According to the cognition of the sparsity of the radar target,a stochastic measurement matrix was established based on the imaging time and the target’s cross-range sparsity.An evaluate criterion of imaging quality was also present.Based on this,the cognitive high-resolution imaging was realized with the limited radar resource.Simulation results indicate that the proposed method can gain the high quality ISAR imaging with much less transmitted pulses and shorter imaging time compare to traditional imaging radar.…”

Adaptive measurement rate setting method in block compressed sensing of images by Ran LI, Zong-liang GAN, UIZi-guan C, UMing-hu W, HUXiu-chang Z

“…Traditional block compressed sensing (BCS) of images uses the same measurement rate to measure each block,but some blocking artifacts appear in the reconstructed image on accounting of varying spatial characteristics in an image.This problem can be effectively solved by adaptively setting different measurement rate for every block.However,these existing methods require original digital image at the collector,which cannot be realized by using practical compressive imaging (CI) devices.In order to overcome this shortage,an adaptive measurement rate setting method is proposed and it can be easily achieved though hardware equipments.This method uses the CS measurements acquired at the collector to estimate the sample variance of each block directly,and then adaptively sets measurement rate of each block in terms of their sample variances and realize rate control.Experimental results show that proposed method can obtain a better qual-ity of reconstructed image than non-adaptive scheme,but there is a gap between proposed method and the adaptive scheme using the true block sample variance since the sample variance estimated in the measurement domain has some deviations.…”

Global efficiency estimation method of complex network based on fractal property by Sheng ZHANG, Weikai DAI, Feng WU, Wenxiang LAN

“…A method of network efficiency estimation based on fractal property was proposed for solving the problems of high complexity and time-consuming calculation of efficiency in large scale networks.Considering the fractal properties of complex network topology,the relationship between network efficiency and node correlation sum was analyzed,and the global network efficiency was estimated by partial nodes.Besides,to rapidly find the fractal properties of complex networks,a fractal property discrimination method based on node correlation sum was proposed.The experimental analysis in the construction network and the real-world network show that the proposed method can accurately and effectively estimate the global efficiency of the network,which reduces the calculation time by at least 90% compared with the original method.…”

Feature dependence graph based source code loophole detection method by Hongyu YANG, Haiyun YANG, Liang ZHANG, Xiang CHENG

“…Given the problem that the existing source code loophole detection methods did not explicitly maintain the semantic information related to the loophole in the source code, which led to the difficulty of feature extraction of loo-phole statements and the high false positive rate of loophole detection, a source code loophole detection method based on feature dependency graph was proposed.First, extracted the candidate loophole statements in the function slice, and gen-erated the feature dependency graph by analyzing the control dependency chain and data dependency chain of the candi-date loophole statements.Secondly, the word vector model was used to generate the initial node representation vector of the feature dependency graph.Finally, a loophole detection neural network oriented to feature dependence graph was constructed, in which the graph learning network learned the heterogeneous neighbor node information of the feature de-pendency graph and the detection network extracted global features and performed loophole detection.The experimental results show that the recall rate and F1 score of the proposed method are improved by 1.50%～22.32% and 1.86%～16.69% respectively, which is superior to the existing method.…”
