中文说明：最小二乘回归分析算法，通过反复训练模板能有较高的识别率，一种流形学习算法（很好用），可实现对二维数据的聚类，包括回归分析和概率统计，是国外的成品模型。
English Description：
Least squares regression analysis algorithm, through repeated training template has high recognition rate, a manifold learning algorithm (very good), can realize the clustering of the two dimensional data, including regression analysis and the probability statistics is foreign product model.
