data mining agglomerative clustering

Compute symmetric trapezoid region based on its sides and height length.

Delta Rule Matlab code

本程序先生成一个“Blocks”信号，然后加上高斯白噪声，再用 db3 小波进行分解，(The Mr. Cheng Xu as a " Blocks" signal, and then add white Gaussian noise, and then ' db3' wavelet decomposed)

fisher源程序代码，马氏距离源程序代码。结果分析(fisher source code)

語音信號是基於時間軸上的一維數位信號，在這裏主要是對語音信號進行頻域上的分析。在信號分析中，頻域往往包含了更多的資訊。對於頻域來說，大概有8種波形可以讓我們分析：矩形方波，鋸齒波，梯形波，臨界阻尼指數脈衝波形，三角波，餘旋波，余旋平方波，高斯波。對於各種波形，我們都可以用一種方法來分析，就是傅立葉變換：將時域的波形轉化到頻域來分析。(Voice signal is based on the timeline of one-dimensional digital signal, where mainly the speech signal in frequency domain analysis. In signal analysis, frequency domain often contains more information. For the frequency domain for about 8 allows us to analyze waveforms: rectangular square wave, sawtooth, trapezoidal wave, the critical damping index pulse, triangle wave, I spin wave, I spin square wave, Gaussian. For all waveforms, we can analyze in a way that is Fourier transform: the transformation of time domain waveform into the frequency domain to analyze)

视频背景非参数估计论文及matlab实现.matlab代码只实现了灰度图的背景估计，论文利介绍的彩色视频处理方法可以自己看看怎么做。(Background and Foreground Modeling Using Nonparametric Kernel Density Estimation for Visual Surveillance AHMED ELGAMMAL, RAMANI DURAISWAMI, MEMBER, IEEE, DAVID HARWOOD, AND LARRY S. DAVIS, FELLOW, IEEE Invited Paper )

说明：  用MATLAB的神经网络工具箱实现三层BP网络(Using MATLAB)
