grouped = df.sort_values('Cluster', ascending = True) grouped.to_excel(excel_writer='data/question_by_cluster.xlsx',sheet_name='questions', engine='xlsxwriter',index=False)
Sorry I did not make myself clear. In this cluster analysis, the final groups (1 and 2) have the minimized possible variance within groups and the maximized possible variance between groups (as I understand). I would like to perform a clustering in which the variance between the groups is ...
1.随机初始化K个聚类中心u1,u2,...,uk 2.根据每个样本和各个聚类中心的距离给每个样本打上标签(例如,x(i)与u3的距离最小,则x(i)的标签为3) 3.计算每个类别的样本的中心(通过均值来计算),更新每个聚类中心的位置 4.重复步骤2、3直到收敛 以上的J函数也成为失真函数,是每个样本点到对应中心距离的平方的均...

Clustering in Excel Microsoft Excel has adata miningadd-in for making clusters. The wizard works with Excel tables, ranges or Analysis Survey Queries. This add-in can be customized, unlike the Detect Categories tool. In addition, the Detect Categories tool is limited to data from tables. ...
(i.e., clusters), such that objects within the same cluster are as similar as possible (i.e., highintra-class similarity), whereas objects from different clusters are as dissimilar as possible (i.e., lowinter-class similarity). In k-means clustering, each cluster is represented by its ...
