Cluster PAM in R - How to Ignore a Column/Variable but Still Keep it The K-Means Plus (KMP) algorithm is an extension of the K-means clustering algorithm that adds new data points to existing clusters when they are too far away from any cluster centroid. The K-Means algorithm, on the other hand, only adds new data points to a new cluster if the point lies within the specified tolerance distance from any cluster centroid.
