case class Cluster (
c :
Int ,
var np :
Int )
The Cluster case class maintains information about clusters, the cluster id, center/centroid, cluster size, and measure of error. Note: the cluster assignment function as an array 'to_c' indicates how points are assigned to clusters.
Value parameters
c
the cluster id
np
the number of points in the cluster (size)
