摘要:

为了从输入信号中自适应地对信号的广义主元进行估计,基于Hebbian线性神经元模型,提出了一种新型广义主元分析算法。该算法通过当前时刻的采样值来估计信号的自相关矩阵,有效地降低了算法的计算复杂度。利用 Lyapunov 稳定性定理进行平衡点分析表明:当且仅当神经元权向量收敛到信号的广义主元时,算法到达稳定状态。仿真实验表明:相比一些同类型算法,所提算法具有较快的收敛速度。

关键词: Hebbian规则, 广义主元, 平衡点, 自适应估计

Abstract:

In order to adaptively estimate the generalized principal component from input signals,a novel generalized principal component analysis algorithm was proposed based on the Hebbian linear neuron model.Since the autocorrelation matrices of the signals were estimated directly from the sampled data at the current time,the proposed algorithm had low computation complexity.Trough analyzing all of the equilibrium points by Lyapunov method,it is proven that if and only if the weight vector in the neuron had the same direction with the generalized principal component,the proposed algorithm attains the convergence status.Simulation results shows that compared with some same type algorithms,the proposed algorithm has faster convergence speed.

Key words: Hebbian rule, generalized principal component, equilibrium point, adaptive estimation
