Aiming at the high alarm rate and poor robustness in the existing intrusion detection algorithms, this paper proposes a cooperative intrusion detection algorithm based on sparse representation.
针对现有入侵检测算法误报率较高和鲁棒性较差的问题,提出一种基于稀疏表示的协同入侵检测算法。
参考来源 - 基于稀疏表示的协同入侵检测算法The graph in SDA is constructed by sparse representation and incorporate semi-supervised discriminant analysis(SSDA),thus the local structure information is automatically modeled,and with the natural discriminative power of sparse representation,SDA can get better performance only resorting to few extra unlabeled samples.
SDA引入稀疏表述并结合半监督判决分析SSDA,通过稀疏重构处理,获得图像的局部结构信息,且由于稀疏表述本身具有的判决性,SDA只需很少样本就能获得较好的效果。
