- BP神经网络基本原理概述:这种网络模型利用误差反向传播训练算法模型,能够很好地解决多层网络中隐含层神经元连接权值系数的学习问题,它的特点是信号前向传播、误差反向传播,简称BP(Back Propagation)神经网络。BP学习算法的基本原理是梯度最快下降法,即通过调整权值使网络总误差最小,在信号前向传播阶段,输入信号经输入层处理再经隐含层处理最后传向输出层处理;在误差反向传播阶段,将输出层输出的信号值与期望输出信号值比较得到误差,若误差较大则把误差信号传回隐含层直至输入层,在各层神经元中使用

- 我提供了一个基于FXLMS的单通道前馈有源噪声控制系统的一个小例子. 为了减少噪声,我们使用控制器C(z)产生另一个“噪声”yw(k)。我们希望它破坏性地干扰X(k)。这意味着控制器必须是传播介质P(z)的模型。采用最小均方算法对控制器系数/权重进行调整。 然而,还有流体介质S(Z)留在致动器和传感器之间。我们称之为二次传播路径。所以,为了使解正确,我们需要用SH(z)来补偿调整过程,这是S(z)的估计(I provided him a little example of a single

- 建立水声信道的射线模型在工程应用上有重要的意义。射线声学是把声波的 传播看作是一束无数条垂直于等相位面的射线的传播,每一条射线与等相位面相 垂直,称为声线。声线途经的距离代表波传播的路程,声线经历的时问为波传播 的时间。声线束所携带的能量即为波传播的声能量。与几何光学相似,射线声学 的描述方法给人直观的感觉,在一定的条件下,射线声学的数学运算也比较简捷, 由射线理论给出的声线图可以给声场以直观、形象的理解。 本模型可以准确的衡量声波在海洋中传播路径(Establishing ray
