Hi, Jaganadh, it looks like you ran k-means on a 2-dimensional dataset (i.e., a dataset with 2 feature variables) and k=3. Thus, the results mean that these three cluster centers (or “centroids”) are the centers of the 3 clusters that k-means attempted to discover. Or in other words, there are 3 globular spheres with its center points

Here’s a figure of how it could look like when plotted in a 2D scatterplot, hopefully, it makes it more clear: https://raw.githubusercontent.com/rasbt/mlxtend/master/docs/sources/user_guide/cluster/Kmeans_files/Kmeans_17_0.png Best, Sebastian > On Apr 29, 2016, at 7:59 PM, JAGANADH G <jagana...@gmail.com> wrote: > > Hi , > After performing clustering, the cluster centers can be extracted via > .cluster_centers_. > > A sample result is > > kmeans.cluster_centers_ > array([[ 1.01505989, -0.70632886], > [ 0.33475124, 0.89126382], > [-1.287003 , -0.43512572]]) > > How can I interpret these values. > > Can somebody help me understanding this document bit detail > > cluster_centers_ : array, [n_clusters, n_features] > Coordinates of cluster centers > > -- > ********************************** > JAGANADH G > http://jaganadhg.in > ILUGCBE > http://ilugcbe.org.in > ------------------------------------------------------------------------------ > Find and fix application performance issues faster with Applications Manager > Applications Manager provides deep performance insights into multiple tiers of > your business applications.
