How do you validate K-means clusters?

The way kmeans algorithm works is as follows:

• Specify number of clusters K.
• Initialize centroids by first shuffling the dataset and then randomly selecting K data points for the centroids without replacement.
• Keep iterating until there is no change to the centroids.

How do you do hierarchical clustering in R?

To perform hierarchical clustering in R we can use the agnes () function from the cluster package, which uses the following syntax: data: Name of the dataset. method: The method to use to calculate dissimilarity between clusters.

What are the two types of hierarchical clustering?

Hierarchical clustering is of two types: Divisive Hierarchical clustering: It starts at individual leaves and successfully merge clusters together. Its a Bottom up approach. Agglomerative Hierarchical clustering: It starts at root and recursively split the clusters.

How is internal clustering validation used in cluster analysis?

Internal Clustering Validation Internal clustering validation, which use the internal information of the clustering process to evaluate the goodness of a clustering structure. It can be also used for estimating the number of clusters and the appropriate clustering algorithm.

How is a dendrogram used for hierarchical clustering?

Dendrogram is a hierarchy of clusters in which distances are converted into heights. It clusters n units or objects each with p feature into smaller groups. Units in the same cluster are joined by a horizontal line. The leaves at the bottom represent individual units. It provides a visual representation of clusters.
