K-Means Clustering is one of the popular clustering algorithm. The goal of this algorithm is to find groups(clusters) in the given data. In this post we will implement K-Means algorithm using Python from scratch.

Mahout是基于Hadoop用于机器学习的程序开发框架,Mahout封装了3大类的机器学习算法,其中包括聚类算法。kmeans是我们经常会提到用到的聚类算法之一,特别处理未知数据集的时,都会先聚类一下,看看数据集会有一些什么样的规则。 本文主要讲解,基于Mahout程序开发,实现分步式的kmeans算法。
对一组向量执行k-means后形成k个簇。 The k-means algorithm adjusts the classification of the observations intoclustersand updates the cluster centroids until the position of the centroids is stable over successive iterations. In this implementation of the algorithm, the stability of the centroids is ...
