我们接下来使用LMSER (Least Mean Square Error Reconstruction) 的模型来构造主成分分析的完整版。 1. 降维与重建 一个主成分是一个方差最大的单位向量。多个主成分就是方差最大的几个单位向量张成的子空间(超平面)。 要想找到这个超平面,只需要最小化数据和数据在超平面投影的距离即刻。 投影向量 (ut):ut=(xt...

This paper presents an algorithm based on the Least-Mean-Square Error criterion modified appropriately for location of outages in distribution systems. Under this scheme, analysis of information obtained remotely can be carried out at the control center before dispatching repair crews to the field. ...
aLMS(Least Mean Square) algorithm, based on minimum mean square error, has the advantages of simple structure, fast convergence and low computational complexity among many adaptive filtering algorithms.

The Least Mean Square (LMS) algorithm, introduced by Widrow and Hoff in 1959 [12] is an adaptive algorithm, which uses a gradient-based method of steepest decent [10]. LMS algorithm uses the estimates of the gradient vector from the available data. LMS incorporates an iterative procedure that...
