FCM 算法用一个Job寻找cluster的中心点。在map的初始化节点,加载初始化(或上一轮迭代的结果)中心点。在map中计算point 和每一个簇的亲和度。在combiner计算同一个cluster的参数,该过程只能计算同一cluster的局部信息。在reduce中首先计算同一个cluster的全局参数,然后计算该cluster是否收敛,输出cluster。...

Problem Description
We have a special convex that all points have the same distance to origin point.
As you know we can get N segments after linking the origin point and the points on the convex. ...
