spring boot 和spark嵌套的demo(spring boot join with spark)

说明：  GN算法是一种分裂型的社区结构发现算法。该算法根据网络中社区内部高内聚、社区之间低内聚的特点，逐步去除社区之间的边，取得相对内聚的社区结构。(GN algorithm is a divisive community structure discovery algorithm. According to the characteristics of high cohesion within the community and low cohesion between communities, the algorithm gradually removes the edges between the communities and achieves a relatively cohesive community structure.)

基本蚁群算法寻找食物,需要TURBOC2运行环境,在vista下要兼容模式运行()

Matlab程序，为统计降尺度方法的一种，可以进行气候变化分析。(Statistical downscaling method)

给定10000个用户和他们对10000个电影的评价，然后通过协同过滤或梯度下降算法，用训练集训练数据，预测出用户对未看的电影的评分，并与测试集对比验证预测结果的准确性(You can learn Chinese,and read the Chinese introduction.)

说明：  在Weka平台运行的ID3算法，对普通的ID3算法做了一点改进，有四个不同的改进，对应了四个不同的算法，适合实验报告和课程报告。直接可以运行，无需调试。(The ID3 algorithm running on the Weka platform has made a little improvement on the ordinary ID3 algorithm. There are four different improvements, corresponding to four different algorithms, which are suitable for experiment reports and course reports. It can run directly without debugging.)

说明：  通过PYTHON编写的爬虫程序，爬取Geoq的人口密度数据(The population density data of Geoq is crawled by a crawler program written in PYTHON)

电影推荐系统中运用的推荐算法是基于协同过滤算法（Collaborative Filtering Recommendation）。协同过滤是在信息过滤和信息系统中正迅速成为一项很受欢迎的技术。
