K-means 更像是一种数据简化技术。 如果事先不知道真正的标签(如您的情况),则K-Means clustering可以使用 Elbow Criterion 或 Silhouette Coefficient 进行评估。 肘部判据法: elbow 方法背后的想法是在给定数据集上针对一系列 k 值(num_clusters,例如 k=1 到 10)运行 k 均值聚类,并为每个 k 值计算总和平方误...

For using theelbow methodwith fuzzy c-means, what should I do in this case? What would be the inputs to plotScree(X,n). It seems that n is the number of clusters, but, what id X? Thanks. Thanks. 댓글 수: 0 댓글을 달려면 로그인하십시오. ...
