Sir while taking the centroid which is not given in the question you have assumed it as random or it is having any formate to take that centroids how can we identify it
Sir in today’s question paper they asked this question in part C. It was specified tht k=2 and they gave C1 and C2 but C1 had 3 points ( instead of 1 point ) and C2 had 3 points. How to calculate ?
Every step is same. Usually we assume random centroids for each cluster. But because they gave points in cluster, the mean of those points will be the initial centroid. Rest steps will be same.
consider 5 points (X1,X2,X3,X4/X5) with following coordinates as a 2D sample for clustering X1=(0.5,175), X2 = (1,2), X3=(0.75,0.25) , X4 (4.1) X5 = (6,3) Illustrate the k means clustering algorithm on the above data set the required number of cluster is 2 and initially clusters are formed from the random distribution of samples C1= {X1,X2,X4} , C2={X3,X5} .. sir intha qn la k=2 so no. of Centroids also 2 than .. centroid ah epadi choose pana , random ah choose panalama , illa C1 and C2 vechi find pananuma ?
Number of centroid is 2 only. No need to choose random centroids. As they have already given set of points in first and second cluster. So you need to proceed from computing average only.

consider 5 points (X1,X2,X3,X4/X5)
with following coordinates as a 2D sample for clustering
X1=(0.5,175), X2 = (1,2), X3=(0.75,0.25) , X4 (4.1) X5 = (6,3)
Illustrate the k means clustering algorithm on the above data set the required number of cluster is 2 and initially clusters are formed from the random distribution of samples
