Matlab7

说明：  两个改进的EM算法，虽然比Matlab自带的运行速度慢，但更易理解算法的原理(Two improved EM algorithm, although more than Matlab s own slow, but easier to understand the principles of algorithm)

LPA是主成分分析算法，用于特征提取和特征空间的降维(LPA code for feature)

说明：  是有关机器学习中讲密度估计的好资料，自己找了很久才找到的，国外人写的很容易懂，乐意分享(Machine learning is related to good information about density estimation, for a long time to find your own, and foreign people to write easy to understand, are willing to share)

this source code is matlab cctime

利用频域滤波消除周期噪声，即用频域带阻滤波器消除图像中的周期噪声。(By using the frequency domain filtering eliminating cycle noise, use frequency domain band-stop filter to eliminate image noise of the cycle.)

用natlab将iris数据聚类为三类。然后将结果与虹膜数据集中的正确结果进行比较，并计算分类精度(You are offered the iris dataset of the UCI dataset. Cluster the data to three categories. Then compare the result with the correct one in iris dataset and compute the classification accuracy.)

说明：  一种新的图像加密方法，把图像看成3位的，来进行3维图像加密。。。。。。。。。。。。。。(A New Approach of Image Encryption Using 3D)
