聚类方法：K-均值
实现语言：java
输入：样本集seed={X1,X2...Xn}
聚类数目：k =3;
过程：
首先用zscore()函数对数据集进行标准化 Xi = (Xi - μ)/σ (μ 为算数均值, σ 为标准差;
从样本中随机抽取k个数据作为初始均值向量{μ1,μ2,...,μk}
repeat:
令Ci =Φ (1 ≤ i ≤ k )
for i=1,2,...,n do
计算样本 Xi 与各均值向量的距离，并把它加入到离它最近的均值向量所在的集合中;
end for
for i =1,2,...,k do
计算每个集合中所有元素的均值向量 μ′i;
if μ′i ≠ μi
μi = μ′i
else
不用更新;
end if
end for
until 当前均值向量均未更新
输出：簇分类 C = {C1,C2,...Ck}
