文本特征词选择-卡方检验

说明：  bwt源代码，希望对大家有所帮助，基于matlab开发的

说明：  有多个文件 可以根据文件名和注释进行选择 提取算法可以根据嵌入算法 自行写出 提供了较好的抗压缩和抗剪切的效果(a number of documents under the file name and choose Notes extraction algorithm can write their own algorithms embedded mention for a better compression and anti-shear effect)

说明：  6QAM通过带限信道，设码元速率为1000波特，传输信道特性为滚降系数为0.75的滚升余弦频谱的滤波器，试建立测试模型并观察接收信号（等效基带信号）的眼图、星座图和相位转移轨迹图。simulink模型(6QAM through the band-limited channel, located at 1000 baud symbol rate, the transmission channel characteristics for the roll-off factor of 0.75 of spectrum raised cosine filter roll and try to create a test model and observe the received signal (the equivalent baseband signal) of the eye diagram, constellation and phase transfer trajectories. simulink model)

Linear Regression with outlier data

伪近邻法确定相空间重构嵌入维数，内涵已生成的典型混沌信号，可以直接使用。(Pseudo-neighbor method to determine the embedding dimension of phase space reconstruction, connotation typical chaotic signal generated can be used directly.)

从国外网站下载的讲述simulink环境下Power System Blockset模块使用方法的手册。(From abroad website simulink environment on the Power System Blockset modules use the manual.)

说明：  关于小波包分析的图像绘制，小波分析，三次分解，单支重构 故障信号(Image registration algorithms based on piecewise linear interpolators (spatiotemporal gradients or block matching) are analyzed to determine subpixel registration accuracy.)

这是我的项目，我试图钢铁故障由KNN和高斯分类器进行分类。数据取自URI资源库和预处理起。
