45306 随后将测量值进行分组处理并采用l q -范数（0 Then the solutions of the sparse vector were estimated group by group with a l q -minimization (0 iteratively re-weighted least-squares (IRLS) algorithm.
45307 与传统压缩感知方法相比，所提方法既可成倍减小随机观测矩阵所需的存储空间，又可在保证图像重构质量的前提下，大大提升重构速度。 Compared with traditional compressed sensing methods, the proposed approach outperformed conventional CS in speed of reconstruction and that it also obtained comparable quality in the reconstruction.
45308 验证实验利用了几种不同大小的随机观测矩阵对2 维灰度图像进行了测试，比较其重构图像的峰值信噪比和重构时间。 Numerical experiments were conducted using gray-scale images, the peak signal-to-noise ratio (PSNR) and the reconstruction time of the reconstruction images were compared with the random matrices with different dimensions. Comparisons were also conducted with other low storage techniques.
45309 测试结果表明，利用所提方法在保证重构精度的前提下，可大大减小随机观测矩阵所需的存储空间（当降低为传统方法的14 096时，仍可得到与传统方法一致的重构质量）， Numerical experiment results show that the STP-CS can effectively reduce the storage space of the random measurement matrix to14 096and decrease tow orders of magnitude of time that for conventional CS, while maintaining the reconstruction quality.
45310 同时极大地提升重构的实时性，对于 1 024 像素×1 024 像素大小的图像，其重构时间可提升近 260 倍。 Numerical results also show that the re-construction time can be effectively improved 260 for the image size of 1 024×1 024.
45311 提出了一种聚类和分类算法相结合的恶意域名检测思路， A new malicious domain name detection algorithm was proposed.
45312 首先通过聚类关联，辨识出同一域名生成算法（DGA, domain generation algorithm）或其变体生成的域名， More specifically, the domain names in a cluster belonging to a DGA (domain generation algorithm) or its variants was identified firstly by using cluster correlation.
45313 然后分别提取每一个聚类集合中算法生成域名（AGD,algorithmically generated domain）的 TTL、解析 IP 分布、归属、who is 的更新、完整性及域名的活动历史特征等，利用 SVM 分类器过滤出其中的恶意域名。 Then, these AGD (algorithmically generated domain) names’ TTL, the distribution and attribution of their resolved IP addresses, their who is features and their historical information were extracted and further applied SVM algorithm to identify the malicious domain names.
45314 实验表明，该算法在不需要客户端查询记录信息的情况下即可实现准确率为 98.4%、假阳性为 0.9%的恶意域名检测。 Experimental results demonstrate that it achieves an accuracy rate of 98.4% and the false positive of 0.9% without any client query records.
