How Do You Select the Centroid in K Means Clustering

Select k centroids. These will be the center point for each segment.Assign data points to nearest centroid.Reassign centroid value to be the calculated mean value for each cluster.Reassign data points to nearest centroid.Repeat until data points stay in the same cluster.

How do you choose the centroid for K-means?

1. Choose k initial centroids.
2. Compute the distance from each pixel to the centroid.
3. Recalculate the centroids after all the pixels have been assigned.
4. Repeat steps 2 and 3 until the same points are assigned to each cluster in consecutive rounds.

What is a cluster centroid?

Cluster centroid The middle of a cluster. A centroid is a vector that contains one number for each variable, where each number is the mean of a variable for the observations in that cluster. The centroid can be thought of as the multi-dimensional average of the cluster.
