• 稀疏表示

  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.
  針對(duì)現(xiàn)有入侵檢測(cè)算法誤報(bào)率較高和魯棒性較差的問(wèn)題，提出一種基于稀疏表示的協(xié)同入侵檢測(cè)算法。

• 稀疏表述

  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引入稀疏表述并結(jié)合半監(jiān)督判決分析SSDA,通過(guò)稀疏重構(gòu)處理,獲得圖像的局部結(jié)構(gòu)信息,且由于稀疏表述本身具有的判決性,SDA只需很少樣本就能獲得較好的效果。
