text-classification
matlab编写的文本分类的程序，可以对已经分好词的文本进行分类，先自己导入数据，用libsvm中的svm进行分类和预测，特征用tfidf算法，还利用卡方检验进行了特征选择，可自行设定阈值。(matlab prepared text classification program, you can have a good word of text classification, classification and prediction using libsvm in svm, characterized by tfidf algorithm, also used the chi-square test was used for feature selection, you can set thresholds on their own.)

Face_and_Face_exsipression_Recognition
One of Biometrics fields is face recognition & face expression recognition ...
1- In face recognition .. we need to design authentication program by training a neural network ,there are two source codes..one of them is based on Discrete Wavelet Transform with Perceptron Neural Network.. and the other based on Discrete Cosine Transform with Perceptron Neural Network ...
2- In face expression recognition .. we defined the condition of the person (nature,happiness,disgust or anger)
this source code is based on Principle component analysis(PCA) ..
* we need to now about digital image processing
,neural network and PCA...

使用高阶累积量对MPSK信号进行调制识别，效果很好，可以达到很高的识别率，我曾论证了好久，确定它的结果没有问题，确实识别率很高(Modulation recognition of MPSK signals using higher order cumulants good effect, and can achieve a high recognition rate, I have argued for a long time, and its results, is indeed a high recognition rate)
