数据降维（6降为3）

信号从发送者传送到接收者往往受到几种形式的变形而消弱，维纳滤波是一种从接收的原始信号中恢复信号的方法。(signal transmitted from the sender to the receiver is often some form of the deformation and weaken. Wiener filter is a reception from the restoration of the original signal signal method.)

This book is the basic book for C/CPP Programmers.

说明：  建立了一级倒立摆的状态空间模型，并采用LQR实现了稳定控制。(establishment of an inverted pendulum of state space models, and the use of LQR achieve stability control.)

主要讲述jeason反演软件的主要流程，对要学习反演的地震解释人员很有用，希望大家多看看(Main main about jeason inversion software process to study the inversion of the seismic interpretation staff was very useful, hope we see more)

In this demo, I use the EM algorithm with a Rauch-Tung-Striebel smoother and an M step, which I ve recently derived, to train a two-layer perceptron, so as to classify medical data (kindly provided by Steve Roberts and Will Penny from EE, Imperial College). The data and simulations are described in: Nando de Freitas, Mahesan Niranjan and Andrew Gee Nonlinear State Space Estimation with Neural Networks and the EM algorithm After downloading the file, type "tar -xf EMdemo.tar" to uncompress it. This creates the directory EMdemo containing the required m files. Go to this directory, load matlab5 and type "EMtremor". The figures will then show you the simulation results, including ROC curves, likelihood plots, decision boundaries with error bars, etc. WARNING: Do make sure that you monitor the log-likelihood and check that it is increasing. Due to numerical errors, it might show glitches for some data sets.
