How to Form Clusters in Python: Data Clustering Methods

WebNov 17, 2024 · For K = 2, the blue cluster has almost twice the width as compared to the green cluster. This blue cluster gets broken down into 2 sub-clusters for K = 3 and thus forms clusters of uniform size. So, the Silhouette plot approach gives us K = 3 as the optimal value. We should select K = 3 for the final clustering on the Iris dataset. WebJan 30, 2024 · Hierarchical clustering uses two different approaches to create clusters: Agglomerative is a bottom-up approach in which the algorithm starts with taking all data points as single clusters and merging them until one cluster is left.; Divisive is the reverse to the agglomerative algorithm that uses a top-bottom approach (it takes all data points of a …
