Description: 程序说明: Form1.cs是应用聚类算法DBSCAN (Density-Based Spatical Clustering of Application with Noise)的示例,可以通过两个参数EPS和MinPts调节聚类。 DBSCAN.cs是实现文件,聚类算法的进一步信息请参考“数据挖掘”或者相关书籍 聚类示例数据来自于sxdb.mdb,一个Access数据库。 已知问题及进一步改进建议: 问题:dbscan.cs行64,SortedList不支持重复键,因此若两个数据点距离相同则无法加入集合 解决:采用人为减小一个微小量,使数据点距离不同且不影响聚类结果 上一解决方案的问题:减小double.Epsilon微小量无助于使SortedList认为两点距离以及不同 解决:采用一个指数增长的微小量,连续重试直至SortedList认为距离已经不同 进一步改进建议:可能通过double的强制转型为内存中的byte类型(假设double型转为8个byte) 然后最后一个byte减去0x01可比较漂亮的解决问题,但是……呵呵,C#中我不会这个操作 也可以自己实现一个SortedList,支持重复键,当然,这,好像是微软应该做的工作了 ^_^ Eric Guo <http://www.cnblogs.com/ericguo/> -procedures : Form1.cs clustering algorithm is applied DBSCAN (Density-Based Spati cal Clustering of Application with Noise) example, two parameters can EPS and MinPts regulation clustering.

Description: DBSCAN是一种性能优越的基于密度的空间聚类算法.利用基于密度的聚类概念,用户只需输入一个参数,DBSCAN算法就能够发现任意形状的类,并可以有效地处理噪声.这里是用C# 编写的,以兰花数据集作为测试数据的代码。-DBSCAN脢脟脪 禄脰脰脨脭脛脺脫脜脭 陆 渭脛禄 霉脫脷脙脺 露 脠渭脛 驴 脮 录 盲 戮 脹脌脿脣茫 篓 拢 庐 脌没脫脙 禄霉脫脷脙脺 露 脠渭脛 戮 脹脌脿 赂 脜脛卯 拢 卢 脫脙禄 搂 脰 禄脨猫脢盲脠毛脪禄 赂 枚 虏 脦脢媒 拢 卢 DBSCAN脣茫 篓 戮 脥脛脺 鹿 禄垄 脧脰脠脦脪芒脨脦 脳
