2类分类高斯混合模型

使用k-means的方法来初始化GMM，

基于EM算法计算出GMM模型参量。

测试GMM模型分别有2个，4个，8个混合成分-2-class classifier with Gaussian Mixture Models. Use the k-means method to initialize the GMM’s

Then improve the GMM models

iteratively based on the EM algo-rithm.

Investigate and report results for GMM s which have 2, 4, 8 mixture components respectively.
