EM算法在神经网络中的应用，可以用来进行视频数据分类。(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.)

利用matlab仿真雷达直射波与地面反射波干涉的雷达方向图。（仰角的大小对雷达作用距离的大小的影响）(Using matlab simulation radar direct wave direction of reflection wave interference with the ground radar chart. (the size of the size of the elevation of the radar range))

将电力市场数据使用小波分解成为两个长度相等的低频和高频小波，然后可以用于灰色模型的建模和波形模型建模！(The electricity market data using wavelet decomposition into two equal length low and high frequency wavelet gray model can then be used for modeling and waveform modeling!)

一本关于控制系统仿真的书的程序 1、文件夹1中的程序是书中的一些仿真。 2、文件2中的是最近做的预测控制、PID控制及逻辑控制的对比综合研究。 3、文件夹3中是与maltab通信的数据采集板的设计文件。包括串口设计、USB1.1及USB20设计。这是最新的设计资料，很有参考价值。 (About a control system simulation procedure one book, folders, one in the book are a number of procedural simulation. 2, document 2 are recent to do predictive control, PID control and logic control study Comparative General. 3, folder 3 are maltab communication with data acquisition board design document. Including the serial design, USB1.1 and USB20 Designed. This is the latest design information, useful reference value.)
