Some linear approaches reported recently without postprocessing to fir system identification are discussed . this paper improves the question of the promulgation of error due to estimating middle parameter frequently in other related methods , and presents a direct algorithm of estimating parameter without estimating middle coefficient . through proper mathematic means , for example , singular value decomposition ( svd ) or total - least squares solution ( tls ) , this algorithm smoothes the noise and improves effectively the estimation performance 和2阶统计量相比,高阶统计量不仅能够有效抑制高斯有色噪声的影响,而且能够揭示随机过程的相位特性,因此,高阶统计量是解决非高斯、非最小相位、非因果系统和有色高斯噪声环境的系统辨识和处理问题的重要分析工具。
Secondly , in respect bayes method is difficult in extracting features and in establishing statistical models , and the capability of no - linear approach is preferably for bp neural netw ork , the method ( bpbayes method ) to combine neural network with subjective bayesian was introduced . in this method , bp neural network was used to replace the experts of relevant domains for applying subjective bayes method 其次,考虑到bayes方法在特征建模上具有较大的难度,而bp神经网络具有较强的非线性逼近能力,为此我们将bp神经网络的输出代替领域专家的知识经验,并用bp神经网络与主观bayes方法结合起来的bpbayes方法对目标进行识别。
