聚类-k均值算法
说明: K-means算法是基于划分的思想,因此算法易于理解且实现方法简单易行,但需要人工选择初始的聚类数目即算法是带参数的。类的数目确定往往非常复杂和具有不确定性,因此需要专业的知识和行业经验才能较好的确定。而且因为初始聚类中心的选择是随机的,因此会造成部分初始聚类中心相似或者处于数据边缘,造成算法的迭代次数明显增加,甚至会因为个别数据而造成聚类失败的现象。(K-means algorithm is based on the idea of partitioning, so the algorithm is easy to understand and the implementation method is simple and feasible, but it requires manual selection of the initial number of clusters, that is, the algorithm is with parameters. The number of classes is often very complex and uncertain, so professional knowledge and industry experience are needed to better determine. Moreover, because the selection of initial clustering centers is random, some initial clustering centers will be similar or at the edge of data, resulting in a significant increase in the number of iterations of the algorithm, and even the phenomenon of clustering failure due to individual data.)

Jsp hibernate树形菜单代码
struts+hibernate树形菜单,只是简单的实现树形菜单,有一种业务逻辑没有考虑,就是当类别目录下同时拥有子目录和具体商品的时候只会显示子目录,而具体商品没显示,只需在标签处理类RecursionTag.java中的printAllCategory方法中添加相应的业务逻辑即可实现,有兴趣自行加工。
整个工程的完整源码打包上传,解压后直接用Eclipse导入就可运行,为方便上传下载去除了/WEB-INF/lib目录下的jar文件,自已添加便可。
