We run the algorithm for different values ofK(say K = 10 to 1) and plot the K values against SSE(Sum of Squared Errors). And select the value of K for the elbow point as shown in the figure. 利用python编写k-means算法,数据样本点数3000,维度为2,如图所示: 数据样本点分布 随机初始化3个...

A modified version of the K-means algorithm with a distance based on cluster symmetry Data mining:有此关键字的文章,更倾向于利用K-means进行数据的预处理或者聚类,目的则是分析实际问题,如 Experimental evaluation of structural features for a speaker-independent voice recognition system The application of ...
K-means remains the most widely used partition clustering algorithm in practice. The algorithm is simple, easily understandable and reasonably scalable.Jamuna, R
1.通过Algorithm design and analysis关键词的增长趋势能分析出,对kmeans算法的改进或者引用数量,一直在增加; 2.通过Image segmentation和Feature extraction这两个关键词的高频,能看出kmeans大量被用在了图像分割与提取各种特征上; 3.其中data mining的变化趋势比较诡异,在2009年达到峰值,后又快速下降;我分析了这些论文...
