Otherwise, scikit-learn’s KMeans algorithm … Webb‘k-means++’ : use the k-means++ method to initialize. ‘random’ : responsibilities are initialized randomly. ‘random_from_data’ : initial means are randomly selected data points. Changed in version v1.1: init_params now accepts ‘random_from_data’ and ‘k-means++’ as initialization methods. Webb初始化的方法有三种:k-means++,random,或者是一个数组。 k-means++能智能的选择初始聚类中心进行k均值聚类,加快收敛速度。 random则是从数据中随机的选择k个观测值作为初始的聚类中心。 也可以传递给init一个数组作为初始化的聚类中心,则这个数组的结 … rc cars drive on water
