时间序列法，通过过去数据来建立相应模型来预测未来数据(Time series, using past data to establish corresponding models to predict future data)

决策树与集成算法，用来分类已知数据种类，希望对编程有帮助(Decision tree and ensemble algorithm are used to classify known data types.)

胡清华邻域粗糙集源码，matlab源代码，方便可用(Hu Qinghua neighborhood rough sets source code, matlab source code, easy to use)

主要利用Python软件，利用KNN算法对垃圾邮件进行分类(This paper mainly uses Python software to classify spam mail by using KNN algorithm)

holt-winters 三次指数平滑算法,时间序列预测算法，带测试数据及Demo(Triple Order Exponential Smoothing, Holt-Winters algorithm, time series prediction algorithm with test data and Demo)

GWR能够实现地理加权回归计算，里面有GWR4操作说明，虽然是英文，但有图片介绍，很容易理解，是GWR模型入门的好工具，适合经济学、数据挖掘等人员使用(GWR can realize geographically weighted regression calculation, including GWR4 operation instructions. Although it is in English, it has pictures to introduce, and is easy to understand. It is a good tool for GWR model entry. It is suitable for personnel such as economics and data mining.)

Java实现Apriori数据挖掘算法,包内还有实例用的数据库 Apriori数据挖掘算法:先找出所有的频集，这些项集出现的频繁性至少和预定义的最小支持度一样。然后由频集产生强关联规则，这些规则必须满足最小支持度和最小可信度。然后使用第1步找到的频集产生期望的规则，产生只包含集合的项的所有规则，其中每一条规则的右部只有一项，这里采用的是中规则的定义。一旦这些规则被生成，那么只有那些大于用户给定的最小可信度的规则才被留下来。为了生成所有频集，使用了递归的方法。 请在jbuilder下编译 配好JDBC驱动 商品如果 买的表示为大写 没买表示为小写的 具体看GetSource.java

通过优化的k-means算法 采用了密度和优化评测函数实现了对Iris等数据集的聚类。 

从数据库获取车辆在一段时间内的所有行驶记录的相关数据，确定所需数据为GPS经纬度坐标和驾驶时长等，QB模型采用MDF的思想,其基本思想为:通过平均直接翻转距离函数定义两条轨迹之间的距离，两条轨迹需要具有相同的经纬度点数，具有相同点数的轨迹最大的优点是对轨迹距离成对计算，且相同轨迹之间具有更高的分辨率，对于轨迹聚类的结果有一定的优化。(Retrieved from the database cars all over a period of time, record the related data, determine the required data for the GPS latitude and longitude coordinates, and the driving time, QB model by adopting the idea of MDF, its basic idea is: flip directly by the average distance function definition of the distance between two trajectories, two tracks will have the same latitude and longitude points, and has the biggest advantages of the same points of trajectory track distance calculation in pairs, and has higher resolution, between the same trajectory for trajectory clustering results have certain optimization.)

基于人工蚁群的的改进Kmeans,进行了改进，效果较好(Based on the improvement of artificial ant colony, Kmeans have been improved and the effect is better)
