摘要: 将频谱理论的一个结论进行了推广,并巧妙地将其运用于前馈网络的分析中,由此得到一种关于前馈网络未知参数的攻击还原方法。即对于一个前馈网络,在非线性滤波函数和抽头集两个参数均未知的情况下,仅由足够长的前馈输出序列就能够实现这两个参数的求解还原。
关键词: Walsh谱, 前馈序列, 前馈网络, 非线性滤波函数
Abstract: In this paper,a conclusion of spectral theory is generalized and applied to the analysis of feedforward networks skillfully.A method for reverting feedforward network parameters is given.For a feedforward network,if the two parameters,nonlinear filter function and tap set,are not given,we can still revert the two parameters only using feedforward sequences which are long enough.
Key words: walsh spectra, feedforward sequences, feedforward network, nonlinear filter function
