We present an overview of the clustering methods developed in Symbolic Data Analysis to partition a set of conceptual data into a fixed number of classes. The proposed algorithms are based on a generalization of the classical Dynamical Clustering Algorit
in many cases, the number of clusters is not known in advance. Various methods can be used to estimate the optimal number of clusters, such as the elbow method, silhouette analysis, or gap
The density-based clustering (DBSCAN is a partitioning method that has been introduced in Ester et al. (1996). It can find out clusters of different shapes and sizes from data containing noise and outliers. In this chapter, we’ll describe the DBSCAN algorithm and demonstrate how to compute ...
Cluster analysis provides a data-driven approach to identifying distinct customer groups based on shared characteristics or behaviors. Cluster analysis can contribute to enhancing customer segmentation in the following ways: Providing more personalized products and messaging ...
cgObj = clustergram(data) performs hierarchical clustering analysis on the values in data. The returned clustergram object cgObj contains analysis data and displays a dendrogram and heatmap. example cgObj = clustergram(data,Name,Value) sets the object properties using name-value pairs. For example...

Data reduction: The amount of data available, N, is often very high in several instances, and as a result, its processing becomes very challenging. In order to organize the data into a number of “important” clusters and treat each cluster as a single entity, cluster analysis can be utili...
