K-mean Algorithm
Initialisation: set seed points
Assign each object to the cluster with the nearest seed point
Compute seed points as the centroids of the clusters of the current partition (the centroid is the centre, i.e., mean point, of th

K-均值聚类算法,属于无监督机器学习算法,发现给定数据集的k个簇的算法。
首先,随机确定k个初始点作为质心,然后将数据集中的每个点分配到一个簇中,为每个点找距其最近的质心,
将其分配给该质心对应的簇,更新每一个簇的质心,直到质心不在变化。
K-均值聚类算法一个优点是k是用户自定义的参数,用户并不知道是否好,与此同时,K-均值算法收敛但是聚类效果差,
由于算法收敛到了局部最小值,而非全局最小值。
K-均值聚类算法的一个变形是二分K-均值聚类算法,该算法首先将所有点作为一个簇,然
