Hierarchical clustering is one of the most popular clustering algorithms after partitioning clustering algorithms like k-means clustering. In this article, we will discuss hierarchical clustering for categorical and mixed data types in python. For this, we will implement agglomerative clustering for datasets having categorical data and mixed data types. How to Perform Hierarchical Clustering for…
You might have studied various tutorials on hierarchical clustering that teach how to plot a dendrogram. This article discusses how to find clusters from a dendrogram in Python. What are Dendrograms? In hierarchical clustering, a dendrogram is a visual tool illustrating how each cluster is composed by drawing links between the clusters based on their…
Agglomerative clustering is a hierarchical clustering method of clustering data points into clusters based on their similarity. In this article, we will discuss how to implement Agglomerative Clustering in Python Using the sklearn module. What Is Agglomerative Clustering? It is a bottom-up approach hierarchical clustering approach, in which each data point is initially considered as…

The K-Modes and K-Prototypes clustering algorithms are partitioning clustering algorithms. We need to specify the required number of clusters while clustering datasets using these algorithms. However, we don’t know the optimal number of clusters beforehand. For this, we can use the silhouette coefficient approach. In this article, we will discuss the Silhouette Coefficient approach for…
Deciding the optimal number of clusters while clustering datasets using partition-based clustering algorithms is essential. In this article, we will discuss the silhouette coefficient in python to decide the optimal number of clusters in k-means clustering. What is Silhouette Coefficient? The silhouette coefficient is a measure of cohesion between the data points in the clusters…
Partitioning-based clustering algorithms have a major issue. While implementing these algorithms, we don’t know the exact number of clusters to be formed. In this article, we will discuss the elbow method to find the optimal number of clusters in k-means and k-modes clustering algorithms. We will also implement the entire procedure of finding optimal clusters…
