1)] that contains the points where we believe that the final centroids
As a result of this loop we may notice that the k centroids
change their location step by step until no more changes are done.
Actually, in this study, for every pixel in an ear image, each pixel is used as a centroid
to generate the aforementioned white circle.
The proposed method choose initial centroids
in two steps.
Clusters 1 and 3 are both above the grand centroid
Because the data is local information, the initial position of the cluster centroid
often deviates from the cluster centroid
of the original data set.
In the first step, the idea is to consider the first k items in the data set as k initial centroids
, then assigned each of the items to the nearest centroid
, with the characteristic that when performing each assignment coordinates are recalculated new centroid
We investigate the role of the number of clusters inferred by our analysis of the documents and the role of the centroids
in the similarity between the computed clusters.
Concordance with morphology diagnosis when using the LSP centroids
was greatest in the TCGA RNAseq data set (agreement, 91%; 869 of 951), possibly because of the extensive pathology review and accuracy of the histologic diagnosis associated with TCGA samples as compared with other data sets.
corresponds to a nonassigned customer.
The coordinates of the four centroids

Clusters GDP per capita (*) ISOC (*) Cluster 1 76.
Step 1) Select randomly k points as the initial centroids
