K-Means Advantages : 1) If variables are huge, then K-Means most of the times computationally faster than hierarchical clustering, if we keep k smalls. 2) K-Means produce tighter clusters than hierarchical clustering, especially if the clusters are globular.K-Means Disadvantages : 1) Difficult to predict K-Value.2) With global cluster, it didn't work well.)

Find the closest (most similar) pair of clusters and merge them into a single cluster, so that now you have one less cluster. Compute distances (similarities) between the new cluster and each of the old clusters. Repeat steps 2 and 3 until all items are clustered into a single cluster of size N.
