By analysis of network traffic (packets), frequent user behavior profiles are mined, and then by comparing the profile similarity, system behavior can be detected in real-time.

通过对网络数据包的分析，挖掘出网络系统中频繁发生的行为模式，并运用模式相似度比较对系统的行为进行检测，进而自动建立异常和误用行为的模式库。

To deal with the similarity of spike temporal profile and frequency feature, a method was proposed to represent spike feature using wavelet analysis technique.

考虑到来自不同神经元的动作电位在时域或频域特征上的相似性，引入小波分析在时频域上对动作电位进行特征描述。
